First, the principle produced by whole circuit diagram.

The present invention is, as active part, there is 4 independent analog switches, crosstalk very little inside electronic relay CD4066 with the integrated circuit of electronic relay class, and each analog switch has control end and two contacts, and the two contacts are respectively input and output end（If being high-order input termination, when control end has signal, output is a high position, and when input is low level, when control end has signal, output is low level）, as an elementary cell, this elementary cell is connected to the exportable high-order new elementary cell with the element of low level output property by single on-off function.This new basic cell structure is to use input end grounding line, with output end by resistant series to system power supply.Its principle is that two switch contacts disconnect, and at this moment output end can export a high position because being connected to source resistance when control end is low level.When control end is for a high position, two switch contacts closure, at this moment output end outputs low level because being connected with ground wire, and now output end is because when connecting ground wire, the source resistance that output end is connected turns into isolation resistance, so power supply will not be with earth short.Wherein the contact control end of elementary cell, is referred to as controlled end, or control end in the present invention.Such base unit is used, multiple independent logic units are devised, overall system of knowing clearly then is designed to by logic unit again.

2nd, explanation in atypical complementation oscillation circuit unit.

Atypical complementation oscillation circuit unit is by complementation vibration Unit one（In Fig. 1 2.1）, complementary vibration Unit two（In Fig. 1 2.2）, complementary vibration Unit one source resistance（In Fig. 1 2.11）, vibration isolated location（In Fig. 1 2.3）, vibrate adjustable protective resistance（In Fig. 1 2.4）, vibration adjustable resistance（In Fig. 1 2.5）, oscillating capacitance（In Fig. 1 2.6）, vibration isolated location earth resistance（In Fig. 1 2.31）, vibration isolation resistance（In Fig. 1 2.7）, complementary vibration output earth resistance（In Fig. 1 2.8）Composition.

The line feature of formation is：It is made up of two units, it is the situation for exporting low level to be connected into during for the closing of contact by complementation vibration Unit one, and it is the high-order situation of output to be connected into during for the closing of contact by complementation vibration Unit two.

During energization,When the control end of the complementation vibration output of Unit one is connected with oscillating capacitance,It is low to be unable to transition,Output end is a high position,So two unit control ends of complementary vibration are a high position,Output end is a high position,It is all high-order situation to form two complementary oscillating unit output ends,Form the first half cycle of vibration,Complementation two unit control ends of vibration are a high position,It is high-order by one unit control end of complementary vibration after oscillating capacitance time delay,Its output end is changed into low level,Two unit control ends of complementation vibration are simultaneously low level,Output end is low,Two complementary contacts of oscillating unit two are changed into low level simultaneously,Form the later half cycle of vibration,Such rule is repeated later,It is two complementary oscillating unit output ends while exporting a high position,The situation of low level is exported simultaneously,Form the abnormal type complementation oscillating circuit of " abnormal type " property,It is the oscillator circuit being made up of the integrated circuit of electronic relay.

In foregoing circuit, oscillating capacitance acts as double effect with oscillation resistance, one is that the control terminal voltage of complementary vibration Unit one and the output voltage of complementary vibration Unit two have certain time delay, this becomes the necessary condition of vibration, two is that oscillating capacitance constitutes duration of oscillation constant with oscillation resistance, the time constant determines line oscillation frequency, so adjustment oscillation resistance can adjust frequency of oscillation.

In foregoing circuit, in order that vibration starting of oscillation is easily, oscillatory process is reliable and stable, designer has made following innovation, and one is to be designed as the oscillating capacitance in circuit electrodeless, is to be formed with two capacitances in series, the electric leakage composition of electric capacity is which reduced, the Q values of electric capacity are substantially increased., two is the resistance to earth that make use of one unit control end of complementary vibration, is formed by two resistant series, a conduct vibration adjustable resistance, and another fixed resistance is used as adjustable limitation.Three be complementary vibration Unit two should not resistance to earth, to simplify circuit, improve reliability.Experiment shows that the circuit is worked good with entirety circuit, with it is very strong can implementation type.

Using such circuit, major advantage is as follows：One is line oscillation reliability, stabilization, good as test power source performance.Two is, as experimental line, to describe a kind of outstanding oscillating circuit, Expand Thinking.

3rd, the explanation of contact switch.

Contact is switched by 1.0, button switch（In Fig. 1 1.0）, switch the first elementary cell（In Fig. 1 1.1）, switch the second elementary cell（In Fig. 1 1.2）, switch the first elementary cell state instruction（In Fig. 1 1.11）, switch the first elementary cell source resistance（In Fig. 1 1.12）, switch guiding electric capacity one（In Fig. 1 1.13）, switch boot-strap resistor one（In Fig. 1 1.14）, switch steering diode one（In Fig. 1 1.15）, switch the first elementary cell earth resistance（In Fig. 1 1.16）, switch the second elementary cell state instruction（In Fig. 1 1.21）, switch the second elementary cell source resistance（In Fig. 1 1.22）, switch guiding electric capacity two（In Fig. 1 1.23）, switch boot-strap resistor two（In Fig. 1 1.24）, switch steering diode two（In Fig. 1 1.25）, switch the second elementary cell earth resistance（In Fig. 1 1.26）, switch input resistance（In Fig. 1 1.5）, switch output diode（In Fig. 1 1.8）Composition.

Its main purpose is the working condition of the atypical complementation oscillation circuit unit of control, atypical complementation oscillation circuit unit is set to turn into the test source for having frequency, or as the dc source that frequency is zero, allow beholder understand resistance element in the case of both power supplys, physical phenomenon.So as to disclose the relation of resistance element and frequency.

Switch is to the control logic of atypical complementation oscillation circuit unit, the output end for switching the second elementary cell is logic control end, the control end of vibration isolated location is connected to by switching output diode, when contact switch is output as low level, switch output diode is back biased, on connected part without influence, vibration isolated location is by the excitation rule normal work for vibrating.So being output as the pulse power of frequency, when the output end of contact switch is for a high position, the switch output diode for being connected is forward bias, thus makes vibration isolated location control end for a high position, and output end is high-order（Because the input for vibrating isolated location is connected to system power supply, therefore when control end has signal for a high position, output end is connected with system power supply）, it is direct current.

Switching the principle for being formed is, the first elementary cell is switched to be connected into for a kind of positive-feedback circuit by what is intersected with switch elementary cell two, if being that the first elementary cell output end of switch is height, then switch elementary cell two output end is low, if instead the first elementary cell output end of switch is low, then it is height to switch the second elementary cell output end.The resistance that the output end of Unit two is connected with power supply is served both functions, and one is when contact is connected with ground wire and isolated from power, is not short circuit, two is when guiding electric capacity into negative pressure, the control signal that steering diode positive pole is connected, takes away with power supply, will not short circuit.

Button switch and boot-strap resistor three, constitute the button circuit of high-order low-end trim in switch, wherein connection turret terminal is button line output, the principle of formation is, when button switch is off-state, because one end of switch input resistance is connected to system power supply, the other end is a high position.When button switch is closure state, because the end of switch output resistance is connected to ground wire, low level is output as.

When being powered, if the output end of the second elementary cell of switch is a high position, the output end for switching the first elementary cell is low level, and when button switch is not pressed, to disconnect, guide line output end is a high position to button switch normally opened contact.Now the output end with guiding electric capacity one, boot-strap resistor one, the first elementary cell of switch is formed charge circuit by switch input resistance.And the output end for switching the second elementary cell with two boot-strap resistor of guiding electric capacity two forms open circuit.When button switch normally opened contact is for closure, button circuit output is low level, and guiding electric capacity one is because being unable to its negative pole of transition as negative pressure state.By the transmission of steering diode one.It is negative to switch the first elementary cell control signal, so that it is a high position to switch the second elementary cell output end, realizes upset.

When button normally opened contact is again off, boot-strap resistor three forms charge circuit with the output end of guiding electric capacity two, boot-strap resistor two, the second elementary cell of switch.And form open circuit with the output end of guiding electric capacity one, boot-strap resistor one, the first elementary cell of switch.When button normally opened contact is for closure, button line output is low level, and guiding electric capacity two is because being unable to its negative pole of transition as negative pressure state.By the transmission of steering diode two.It is low to switch the second elementary cell input, so that it is a high position to switch the second elementary cell output end, upset is realized again, and later inversion principle is the same.

Using mainly there is benefit following prominent after electronic switch, one is that button is that one kind touches button, while also allowing for installment state instruction.It is overall high-grade, benefit from, two is that button belongs to a kind of common components, it is easy to bought.Three is that button switch does not produce fly line in production, directly can produce and contact with printed panel, while circuit reduction, thus product quality can be further ensured that.Four be as make experimental line be conducive to expand teenager's thinking.

4th, the explanation of double amplifying units.

The line feature one of this part is that the oscillating unit of Part I has been collectively constituted using atypical complementation oscillation circuit unit, and two is to lift elementary cell by two of this part（5.3 and 5.5 in Fig. 1）, commutation diode（5.0 in Fig. 1）, one-level electric capacity（5.01 in Fig. 1）, two-stage hoisting diode（5.1 in Fig. 1）, two-stage hoisting electric capacity（5.11 in Fig. 1）, three-level lifting diode（5.2 in Fig. 1）, three-level lifting electric capacity（5.21 in Fig. 1）, one-level lifting elementary cell earth resistance（5.31 in Fig. 1）, one-level lifting elementary cell source resistance（5.32 in Fig. 1）, penetrate with triggering resistance（5.7 in Fig. 1）, penetrate with amplifier tube（5.8 in Fig. 1）Part II is collectively constituted.

The main purpose of the unit is that the voltage of atypical complementation oscillation circuit unit can produce the situation of voltage decline after frequency element is testing capacitor, inductance（Because there is a capacitive reactance, or induction reactance pressure drop）, after lifting circuit behind the part, energy has been lifted, thus is more explicit display effect.

The circuit must have two characteristics of weight, and one is that, with good amplification characteristic, two is when lifting the input no signal of circuit, to export no signal, is that output does not produce additional static current potential.

The principle of formation is, two inputs of elementary cell that the oscillating unit signal of Part I has been passed in this grade, so the two the elementary cell output ends in this grade are respectively the output state of low state high, and capacitance connection is lifted in the output end of the two elementary cells, so the state change of height can occur therewith.

After demonstration element connects circuit, DC voltage is filled with one-level electric capacity after over commutation, when the first elementary cell of voltage increase output end is low, one-level lifts electric capacity and charged to two-stage hoisting electric capacity by two-stage hoisting diode, as one times of voltage.

When the first elementary cell output end is for a high position, the voltage of one-level electric capacity turns into double voltage through the lifting elementary cell output end superposition of overvoltage one-level, when two-stage hoisting elementary cell output end voltage is low level, two times of voltages charge on three-level lifting electric capacity, when two-stage hoisting elementary cell output end voltage is high-order, two times of voltages are superimposed the voltage that trebles by the output end voltage, are consequently formed lifting circuit.

The present invention using two elementary cell three times voltage lifting circuits have the advantages that five it is prominent：

One is the one-level lifting electric capacity when no signal is input into, no-voltage, so output can not possibly produce multiplication of voltage effect.It is zero volt, the output for being the circuit does not produce additional static current potential.

Two is that it is of special importance that the voltage on one-level lifting electric capacity is based on the voltage after test resistance element step-down, resistance is of different sizes, and the magnitude of voltage of generation is also different, so the booster tension quantity for producing also differs not sample.That is to say that the basis of three times voltage depends on the voltage after resistance element step-down, output and the electric capacity capacitive reactance tested of lifting circuit have direct relation.

Three because employ two elementary cell three times voltage lifting circuits of double amplifications, efficiency high, required time is relatively few, so sensitivity is higher.

Four is that the output of the circuit and diode-type partial pressure unit have emitter follower to make to isolate, so the circuit has good load capacity.

Five is as Part I, as enjoying jointly, and to be only used as isolation with two lifting elementary cells of this part with atypical complementation oscillation circuit unit, simplifies circuit, has positive meaning to improving reliability, production.

5th, the explanation of diode-type partial pressure unit.

Diode-type partial pressure unit by Multilevel partial-pressure diode, Multilevel partial-pressure resistance, multi-stage initialization device composition partially partially under diode, partial pressure under aisle resistance, partial pressure over the ground.

It is characterized in：Every grade of partial pressure diode by two Diode series into, every grade of partial pressure Diode series, its series connection point connects partial pressure aisle resistance over the ground, each series connection point turns into a partial pressure output point, because the parameter of each diode is equal, so as to from input to earth terminal, form the stepped-up voltage output of voltage.When input terminal voltage is high, then the quantity of the partial pressure diode that can puncture is more.Then have the output point of high-order output many, when the voltage of the output of each output point, higher than connected preset device door when, the closing of contact of preset device two, output end connection system power supply output is high-order, and paired display unit is energized, so as to display occur.

The unit is made up of multiple preset devices, and the input of each preset device is connected to system power supply, and the startup of each preset device is required for the partial pressure output point output of partial pressure level high-order, thus ensure display unit will not malfunction.

6th, in light display level display driver element explanation.

Due to being made up of three display driver elements in each light display level.Signal is stronger, and the display unit of excitation is more, and shown luminous instruction is more.It is luminous to indicate the bright state feature to be：As continuous-flow type.It is luminous to indicate bright to be innervation.Luminous instruction is bright must be more remote, and its whole night is that abstract electric current is likened into current.

So during diode-type partial pressure unit output point no-voltage, all equal no-voltages of preset device input for being connected, the luminous instruction of display unit does not work, so not working.When the partial pressure output point of diode-type partial pressure unit is into a high position, the preset device output end for being connected is height, and power supply and the system power supply of display driver element are connected, so display driver element turns into working condition, lighting, it is glittering to indicate.

The line construction of each display unit is the same.So only with the first display unit explanation.

A feature in display unit circuit is that each display unit has an independent live wire,（It is VCC2 in figure）With system power supply line（VCC）It is not attached to, with box indicating, each display driver, the power end of discoloration driver need the power end being connected to connect together to each display unit with unit line in display unit, are in the accompanying drawings（VCC2）, the output end of the point and corresponding preset device is connected.Therefore when preset device output end is for a high position, the independent live wire of display unit（It is VCC2 in Fig. 2）With system power supply（VCC）It is connected, the cell operation.Conversely, when the output end of preset device is low level, independent live wire is not connected with system power supply, and the live wire of display unit does not work without electricity.

At steady state, specific the first bright rule of luminous instruction is：After circuit stability, the luminous instruction of the first display driver institute band was bright before this, and the luminous instruction of second and third display driver is put out, and was afterwards that the luminous instruction of display driver is bright, and first puts out with the luminous instruction of three display drivers.Third for the luminous instruction of the 3rd display driver is bright, the luminous instruction of first and second display driver is put out.Then circulate.

The reason for forming glittering driving be：Because three display drivers（In Fig. 2 9.111,9.112,9.113）In design, inclined resistance is inconsistent with other two in first display driver control end, two contacts for easily causing the first display driver first close, and output end is first low level, and the luminous instruction of the display driver institute band is bright, because the first commissure capacitance voltage now between the first display driver output end and the second display driver is unable to transition, into negative pressure, output end is a high position to second display driver control signal, and institute's band is luminous to be designated as putting out.Inclined resistance in second display driver control end（In Fig. 2 9.1123）Charged to the first commissure electric capacity, when voltage controls terminal voltage more than the second display driver, second display driver output end is low level, the luminous instruction of the second display driver institute band is bright, the second commissure capacitance voltage between 3rd display driver control end and the second display driver output end is unable to transition, into negative pressure, output end is a high position to 3rd display driver control end, and institute's band is luminous to be designated as putting out.Now inclined resistance in the 3rd display driver control end（In Fig. 2 9.1133）Charged to the second commissure electric capacity, when voltage is more than the 3rd display driver control end threshold voltage, 3rd display driver output end is low level, the luminous instruction of the 3rd display driver institute band is bright, because now the output end of the 3rd display driver is unable to transition with the 3rd commissure capacitance voltage of the first display driver control end, into negative pressure, output end is a high position to first display driver control end, and institute's band is luminous to be designated as putting out.Now inclined resistance charges to the 3rd commissure electric capacity in the display driver control end, and to after threshold voltage, the first display driver output end is low, and the luminous instruction of institute's band is bright again, as circulation.

6th, the explanation of discoloration driver element.

Each discoloration driver element by two discoloration drivers, two discoloration driver guiding electric capacity, two discoloration driver boot-strap resistor, two discoloration driver earth resistance, two discoloration drivers source resistance and differential circuit constitute, line feature is, two anodes of common cathode luminous tube respectively connect a discoloration driver element in each luminous instruction, and the power supply of two discoloration driver elements links together, so two discoloration driver element synchronous workings.

The Main Function of the unit is to make display luminous tube reveal two kinds of colors of rule to carry out flashing for continuous-flow type, the flowing as water.

Specifically rule is：Luminous instruction is that the first colour light emitting flashes first, after last display driver starts, new endless form presses second color, and circulation is flashed forward with what original mode carried out continuous-flow type, after last display driver starts, the endless form of third time presses the first color again, and what original mode carried out continuous-flow type flashes forward circulation, then by such endless form, circulation is gone down forever, and prime will not be equally with this color.

The reason for producing two kinds of color variations rules.

Two output ends of two discoloration drivers in discoloration driver element are connected to two anodes of common cathode luminous tube respectively, and the characteristic of common-anode luminous tube is, when the first anode is for a high position, it is a kind of color, when second plate is for a high position, it is then second color, is the third color when two anodes are all a high position.

Discoloration driver is collectively constituted by first and second discoloration driver and peripheral element, wherein the control end of the second discoloration driver is connected with differential capacitance.The tie point of two guiding electric capacity is input in discoloration driver.The input has been connected to the output end of last display driver.The control end of the second discoloration driver is connected with differential circuit, and the control end is first a high position when energized, and output end is low level.The output end of the first discoloration driver is a high position.Ensure that the color of starting.

When the output end of last display driver is for a high position, at this moment can be with the low order end of the second discoloration driver, the guiding electric capacity of the second discoloration driver, the boot-strap resistor of the second discoloration driver forms charge circuit, when the output end of last display driver is low level, finished because the guiding electric capacity of the second discoloration driver has charged, it is unable to transition, its negative pole turns into negative pressure, by the transmission of steering diode, the output of the second discoloration driver is changed into high-order from low level, because the second discoloration driver and the output of the first discoloration driver are connected to feedback with control end, so when the second discoloration driver is output as a high position, first discoloration driver is output as low level, form upset.When the output end of last display driver is for a high position, at this moment the low order end again with the first discoloration driver forms charge circuit, is consequently formed circulation.

So luminous indicate when circulating first time, the two-color diode first anode is a high position, and during circulation, luminous tube is flashed with the circulation that the first color makees continuous-flow type.When being triggered again, discoloration driver upset, common cathode luminous tube second plate is a high position, and it is a high position that the first anode is constantly pressed later, and then second plate is bit map high, and color change is constantly carried out with this rule, and this color will not be identical with last time color.

7th, music sound explanation.

When the second discoloration driver output end is high, musical film has direct current channel, so sending music.

Have the advantages that after implementation following prominent：

First, there are following characteristics as a kind of science popularization scope：

1st, electricity is important content in physics.And for beginner, understand relatively easy to galvanic, and the influence to the electric current with frequency to circuit element can feel abstract.And the demonstration of this instrument can make the abstract concept of beginner become actual.Therefore there is positive effect to studying electricity in depth.Concrete condition have it is following some：

（1）, because this demonstrator in abnormal type complementation oscillation source can contact switch switching under, the pulse power can be changed into, it is also possible to be changed into direct current, it is possible to clearly demonstrate out resistance element（Such as electric capacity, or inductance）In the situation that frequency is zero（It is direct current）, it is entirely different with the physical phenomenon in the case of the pulse current with frequency.

Such as electric capacity（Electric capacity its construction is two pieces of disjunct conductive materials planes）, this special construction under DC state, is being only possible to the disposable charging in transient state ground, finally as off state（Show as display portion luminous tube transient state it is bright once, then put out entirely）.But under the pulse power of frequency, theatrical change is but there occurs, because this disjunct two sides can be smoothly through electric current.

It is a good good conductor if inductance is under DC state,（The luminous tube for showing as display portion is always bright state, into flowing water shape, and from the beginning to the end）But in the pulse current by frequency, but under the pulse power of frequency, theatrical change is but there occurs, because this end to end wire but has resistance to electric current, its physical characteristic changes completely.（The luminous tube for showing as display portion only manifests the bright state of part, is reduced into flowing water shape, i.e. light brighten the hair pipe）.

（2）, the atypical complementation oscillation circuit unit of the present invention frequency-adjustable.Can demonstrate out that frequency is higher, the impact effect to frequency element is bigger, such as same parameters electric capacity, frequency is higher, and conduction is better,（The luminous tube for showing as display portion manifests the bright state of part, and into flowing water shape, light brighten the hair pipe increases）.

And for example same parameters inductance coil, frequency is higher, and the resistance that it is presented is bigger.（The luminous tube for showing as display portion manifests the bright state of part, is reduced into flowing water shape, but light brighten the hair pipe）.

（3）, can demonstrate out, under same voltage, electric capacity is bigger, and capacitive reactance is smaller, is smaller to the resistance of electric current, and inductance is bigger, then induction reactance is bigger, is bigger to the resistance of electric current.（The luminous tube for showing as display portion manifests the bright state of part, and into flowing water shape, light brighten the hair pipe increases）.

（4）, the main inside reason of the size that capacitive reactance is presented in electric capacity can be demonstrated out, disjunct two conducting surface in inside of such as electric capacity is bigger, then capacitive reactance is smaller, and the insulating barrier between two conducting surfaces is thicker, then capacitive reactance is smaller.（The luminous tube for showing as display portion manifests the bright state of part, and into flowing water shape, light brighten the hair pipe increases）.

（5）, the main inside reason of the size that induction reactance is presented in inductance can be demonstrated out, the diameter of such as coil is bigger, then induction reactance is bigger, otherwise induction reactance is fewer,.（The luminous tube for showing as display portion manifests the bright state of part, and into flowing water shape, light brighten the hair pipe increases）.

（6）Whether induction reactance also has permeability magnetic material relevant with coil, and relevant with the property of permeability magnetic material.

2nd, excellent performance master be now embodied in it is following some：

（1）, due to having display driver element and discoloration driver element in light display level, two kinds of units have collectively constituted the function of uniqueness, and what this unique function formd two kinds of rules flashes instruction, and novel and unique can not be looked into circuit, and one is.Signal is stronger, and shown junior unit is more, and luminous tube is bright must be more remote.Two is luminous tube bright to after termination, can produce loop cycle, and the tube light that lights is innervation.As a kind of gradual, continuous-flow type, three is every time that new circulation is different with previous color, is shown in light, and entertaining is full of in demonstration.This circuit being made up of this logic element does not have data introduction.

（2）, presentation process light and sound show and deposit, when glittering luminous tube periodically sends transient state music in a timing.Delight effect is increased, beholder teaches through lively activities.

（3）, contact switching manipulation be button, have benefit following prominent, one is that button is that one kind touches button, good hand touch.Two be often by a state transformation once, it is easy to operate.Three can be clearly show be current control state, DC state in this way, at this moment indicator lamp is a kind of color, in this way the frequency power source of pulse, again can be overall high-grade in clear Chu Ming Liao into another place's color.Four is that button switch does not produce fly line in production, directly can produce and contact with printed panel, thus can be further ensured that product quality.Five is that button belongs to a kind of common components, it is easy to bought.These advantages, also allow for hookup purchase.

（4 ）, display quantification effect it is good, the range of components of demonstration is wide, circuit stabilization.One because double amplifying units, in the absence of initial potential, as long as be prime without input signal, diode-type partial pressure unit exports each output point and does not export a high position, and display portion does not show.Hereby it is ensured that display is accurate.Two because double amplifying units of this instrument thus have sensitivity higher, and to when capacitive reactance is larger, can also clearly show that, three is the amplifying circuit has amplification in pulse condition and DC state.More flexibility.Adaptive surface is wide.

（5）, the concept of resistance, insulator, electric current can be demonstrated out, demonstrate out when the timing of voltage one, the relation between electric current and resistance.Resistance is bigger, the smaller visual effect of electric current.More basic electricity knowledge is set up with the student for making the age smaller.

（6）, the elementary cell made of present invention electronic relay, dependable performance, the contact between constituent parts rationally, so overall circuit logic is strong, science.

3rd, because above-mentioned some reason, while this instrument of institute belongs to the popular demonstrator of primary.Adapt to wide, primary school and middle school and Popular Science Education are all well suited for, have much room the need for society.Good social benefit can be produced.

4th, the active part of this instrument is in addition to only one triode, entirely a kind of integrated circuit of model, and this is to buying, plug-in unit, all very easily, so easily production.

5th, debug simple, without high end equipment, be easy to minitype enterprise to produce.

6th, had the advantage that and feature as a kind of experimental self-control circuit.

Circuit of the present invention is simplified, and each unit contact science, operability is very strong, therefore can be conigenous row experiment installation with heuristics, by self-control, can further improve students ' practical ability and practical level, and this has positive meaning to improving students ' quality.And the present invention there are following characteristics in self-control, thus it is very suitable for self-control.

1st, active part is in addition to a triode, all electronic integrated circuit relay groups into elementary cell combination form, therefore it is easy to beginner to the understanding of the adhesive integrated circuit, due to active part single varieties, give prominence to the key points, beginner is conducive to learn, it is to avoid numerous and be weary of studying, or not rotten situation of grasping too much.And this script only has the device of on-off function, it is high-order with low most basic logic element that can constitute with output end, followed by and various basic logic circuits can be formed, various functions of series can be developed into again, beginner's positive thinking thus can be guided, imagination space is expanded, is conducive to education of improving the quality.

2nd, each several part independence, partly can check for unit is powered.And each is partially filled with certain interest.（The display concrete condition of its light and sound is as previously described）.

3rd, between each several part between connect science, will not substantially produce failure, thus complete part debug after, so that it may complete overall work.
