PTC电阻热耗实验仪研制

Develop Heat Rate Instrument About the Thermal Resistor of PTC

本文阐述了ＰＴＣ电阻热耗散实险仪的结构和原理。实验结果表明，该实验仪可以调控ＰＴＣ电阻在机油中的运动速度，当ＰＴＣ电阻速度增加时，通过ＰＴＣ电阻的电流则按指数规律增加。

This paper set forth structurre and principal about the heat rate instrument of thermal resistor PTC.The results show that the instrument is able to control motion speed in engine oil of PTC thermal resistor,and the current of PTC resister increases by index law for increase of motion speed about PTC resistor.
