Description
Technical field
This utility model relates to a kind of computer aided experimental teaching field, is specifically related to a kind of based on computer assisted gas experiment system.
Background technology
Gas experiment law is the important content in calorifics, is study and the basis of research calorifics.This law is an experimental laws, the experimental technique that General Physics and Middle School Physics textbook (people teaches version) are mentioned, and demonstrates these laws roughly.Need experimenter to measure three state parameters of gas when testing the most simultaneously, degree of accuracy, reliability, real-time, degree easy to use are not the most fine, and measure substantial amounts of data, due to experiment for a long time, experimenter can be made tired out and affect experiment effect (therefore many teachers the most do not do this experiment and use the mode made an ineffectual attempt on blackboard to impart knowledge to students, and affect student's grasp to this partial knowledge).
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, a kind of simple in construction is provided, one reasonable in design, easy to use is based on computer assisted gas experiment system, it uses and utilizes sensing technology and computer technology, make gas pressure intensity, temperature, three physical quantitys of volume be simultaneously displayed on screen, and carry out data process in real time, describe response curve image, three experimental laws and the equation for ideal gases of gas can be verified intuitively, there is application value.
For achieving the above object, the technical solution adopted in the utility model is:
One described in the utility model is based on computer assisted gas experiment system, including the gas experiment instrument for operation, for the computer analyzed and amplifying circuit, gas experiment instrument includes air cavity and is arranged on the pitch brace in described air cavity, described gas experiment instrument side is provided with the slide-wire rheostat linked with described pitch brace, the outlet side of described air cavity is installed with gas conduit, described gas conduit end is provided with pressure transducer, described air cavity is also equipped with temperature sensor, described slide-wire rheostat, pressure transducer is all connected with data collecting card with temperature sensor, described data collecting card is connected with described amplifying circuit, described amplifying circuit is connected with described computer.
Further technical scheme, described air cavity is cylinder.
After using said structure, this utility model has the beneficial effect that this utility model, and it uses slide-wire rheostat to link with pitch brace, Length Quantity is converted into electrical quantities, thus the volume V of gas is obtained according to the cross-sectional area of air cavity, pressure P and temperature T are measured in recycling pressure transducer and temperature sensor respectively, through amplifying circuit, the signal of telecommunication is shown in a computer, data process can be carried out in real time, describe response curve image, three experimental laws and the equation for ideal gases of gas can be verified intuitively, there is application value.
