摘要

ＳｎＯ２气敏电阻在含ＣＯ空气中的振荡机理，给出了气敏电阻在含ＣＯ空气中的热学方程式，获得了振荡周期τ的近似表达式，气敏电阻起振的必要条件及振荡周期τ与ＣＯ气体浓度Ｎ、工作电压Ｖ的关系。

Abstract

The oscillation mechanism of self-heating SnO2 sintered sensor in CO gas and air is discussed and the thermal equation of the sensor resistance is given.We have obtained the approximate expression of oscillation period for sensor resistance and the necessary condition of the cause of oscillation.We have also gotten the relationship between the frequency F

the CO concentration N and the working voltage V.
