| Abstract: | In order to solve the influence of heat-inertia that results in the thermistor's resistance and temperature doesn't transfer in-phase,a measurement system was designed by LabVIEW.By this system and a voltage-divided circuit,we can transfer thermistor's resistance and temperature in-phase and improve the accuracy of measurement.It's a new idea of measurement and it is a typical example of applying virtual technology into physics experiment. |
