Abstract
Disclosed is a soap bubble non-polar molecule polarization demonstration instrument which belongs to the field of teaching instruments and relates to a demonstration instrument for simulating the polarization process of a non-polar molecule with a soap bubble. The instrument is composed of a reflecting mirror and a polar plate which are placed on a track in parallel, the polar plate can move along the track, a gas nozzle facing downward is arranged in front of the upper part of the reflecting mirror and is 1-2cm from the reflecting mirror, and the gas nozzle is connected with an inflating ball provided with an adjusting valve. When the instrument is in use, the polar plate is connected with a high-voltage power supply, a soap bubble is blown by the gas nozzle and is adsorbed on the reflecting mirror, the soap bubble remains in a spherical shape after being reflected by the reflecting mirror, and the soap bubble is elongated under the action of an electric field, thereby simulating the polarization process of a non-polar molecule. According to the utility model, the polarization process of a non-polar molecule is simulated by making use of lightness and easy deformation of the soap bubble and the function of the reflecting mirror, thus filling the gap for the demonstration of the polarization of a non-polar molecule.
Description
Technical field
The utility model belongs to the instruments used for education fields, relates to a kind of demonstrator with soap bubble simulation nonpolar molecule polarization process.
Background technology
Polarization of dielectric is content important in electromagnetics teaching.Polarization of dielectric includes utmost point molecular polarization and nonpolar molecule polarization.Wherein the principle demonstration instrument of polar molecule polarization existed already, and the principle demonstration instrument of nonpolar molecule polarization did not also occur, reason is, the material that just can find out distortion by faint electric field force seldom, be exactly in addition such material be generally liquid, it is in bond that but liquid is difficult to outside container, thereby be difficult to see the distortion of its integral body.
Summary of the invention
In order to realize the demonstration of nonpolar molecule polarization, the utility model provides a kind of demonstrator of simulating nonpolar molecule demonstration polarization process that is out of shape with soap bubble under electric field action.
To achieve these goals, the utility model has been taked following technical scheme:
Soap bubble formula nonpolar molecule polarization demonstrator is comprised of catoptron and pole plate, and described catoptron and described pole plate are placed in parallel on track, and the pole plate track-movable; Front on described catoptron top arranges valve, valve down, and with mirror separation 1-2 centimetre, valve connects the inflating ball with variable valve.This device utilizes valve can blow out soap bubble; Utilize catoptron that the soap bubble that is attached on catoptron is presented spherical.
Described pole plate moves by hand leading screw, like this can fine adjustment catoptron and pole plate distance, and when pole plate produced electric field soap bubble is elongated, accommodation reflex mirror and pole plate distance made soap bubble produce distortion and do not pulled open.
Be provided with lighting device before described catoptron, can make like this soap bubble more clear, as described in catoptron edge edge one circle light emitting diode.
The utility model utilizes the effect of the light and handy yielding characteristics of soap bubble and catoptron, has simulated the process of nonpolar molecule polarization, has filled up blank to the demonstration of nonpolar molecule polarization.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the utility model soap bubble formula nonpolar molecule polarization demonstrator.
In figure: 1, pole plate, 2, catoptron, 3, valve, 4, tracheae, 5, hand leading screw, 6, slide rail, 7, the pole plate base, 8, base.
Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment, the utility model is described further.
Pole plate 1 in the present embodiment and catoptron 2 are installed on base 8, are provided with two parallel slide rails 6 in base 8 as track, are provided with hand leading screw 5 between two one slide rails 6.Pole plate 1 and catoptron 2 be arranged in parallel, catoptron 2 is fixed in the end of slide rail 6, pole plate base 7 is set below pole plate 1, described two one slide rails 6 and hand leading screw 5 pass pole plate base 7, pole plate base 7 can slide on two one slide rails 6, and pole plate base 7 is provided with the screw thread that coordinates with hand leading screw 5, rotates hand leading screw 5 and can be with movable plate electrode base 7 to move on slide rail 6.
Valve 3 is installed on catoptron 2 tops, leaves the 1-2 cm distance between valve 3 and catoptron 2.Valve 3 is connected with inflating ball with variable valve by tracheae 4.
When this device used, pole plate 1 was connected with an electrode of high-voltage power supply; Valve 3 is dipped in suds, blow out a soap bubble with inflating ball, because valve is nearer apart from catoptron, soap bubble can be adsorbed on catoptron, and by the reflection of catoptron, soap bubble still presents sphere-like.Make pole plate 1 near catoptron by rotating hand leading screw 5, the soap bubble in catoptron polarization charge occurs at the electric field action lower surface, is attracted by pole plate 1, and soap bubble is elongated, and spherical soap bubble becomes elliposoidal, has simulated the polarized form of nonpolar molecule.
In order to make soap bubble more high-visible, can install lighting device additional between pole plate 1 and catoptron 2, as a circle light emitting diode is set at catoptron 2 edges, when light emitting diode was lighted, soap bubble can be more clear.
