Abstract
The invention relates a Doppler effect comprehensive test instrument improved device. A data measuring scale is additionally adopted based an original device. The data measuring scale comprises two parts, namely, a bracket and a calibration board. With the data measuring scale of the invention adopted, the problem of inconvenient data measurement of the original device can be solved. The data measuring scale is simple in operation, beautiful and practical. With the data measuring scale adopted, the probability of making mistakes of student ,in a use process can be reduced, measurement accuracy can be improved, and experimental error caused by man-made negligence can be decreased. The data measuring scale of the invention has the advantages of simple structure, convenient operation, beautiful appearance, high practicality, low cost and convenience in production and use.
Description
Technical field
The present invention is used for Doppler effect experimental apparatus field.
Background technology
In college physical experiment teaching, Experiments of Machanics are important ingredients." Doppler effect Comprehensive Experiment " as the important experiment of terms of mechanics, is physical experiment course in universities generally offering of domestic and international colleges and universities.Current Doppler effect comprehensive test instrument can make preliminary understanding Doppler effect, the Verify Newton Second Law of student, obtain acceleration of gravity, measures the parameters such as simple harmonic motion cycle.Doppler's experiment is theoretical and the most reasonable experiment of actual application, has certain advance, be preferable instruments used for education in physical experiment apparatus.But due to instrument mechanical composition part design not reasonable, result in experimental data measure time inconvenient operation, easily due to human negligence strengthen error.When making a search simple harmonic oscillation experiment, although have scale on guide rail, but owing to guide rail is distant with spring, be difficult to reading, and easily produce error, generally require the elongation being individually equipped with tape measure spring for every instrument.
Summary of the invention
In order to solve the problems referred to above, the present invention devises a kind of Doppler effect comprehensive test apparatus DATA REASONING scale, and newly-increased surveyors' staff is fixed on guide rail, can apply to the experiment of Doppler's comprehensive test instrument research simple harmonic oscillation, facilitates the measurement of experimental data.Put down when needing and measuring and by the left and right screw up-down adjustment that is connected with guide rail to suitable position, can be packed up when not needed, not affect subsequent experimental and carry out.As shown in Figure 1.Present configuration is simple, low cost, it is simple to produces and uses.
Accompanying drawing illustrates:
Fig. 1 apparatus of the present invention schematic diagram；
Fig. 2 detail view of the present invention.
Specific embodiment
Newly-increased surveyors' staff is made up of, as shown in Figure 2 support and scaling board two parts.Support is fixed on guide rail, for the upper-lower position of regulation scale, by two, left and right screw regulation scale position on guide rail.Scaling board is connected on support, and the used time is not packed up and guide rail parallel, is put down vertical with guide rail during measurement.When experiment needs the relative position measuring spring, launch test board, the knob that regulation is fixed on guide rail, make scaling board slide up and down, during regulation, note left-right balance.When need not measure, turning knob 3, packing up scaling board so that it is be parallel to guide rail, carrying out in order to avoid affecting experiment.
Claims (2)
1. Doppler effect comprehensive test apparatus increases DATA REASONING scale newly, it is characterised in that: described surveyors' staff includes support and scaling board two parts.
2. support is wide with guide rail, is advisable can fix on guide rail, each regulation screw about support；Scaling board width is more than half of guide rail width and is less than guide rail width, is advisable close to spring when length is to measure.
