用联立法检测还原性气体种类和浓度

Determination of the reductive gas types and their concentration with combination method

本文叙述了利用气敏电阻的工作电流是还原性气体种类和浓度函数的特点,可通过两个不同种类的气敏电阻联立求出空气中只含某一种还原性气体种类和浓度的方法。

This paper described a method that the type of unknown reductive gas contained solely in the air and its concentration can be obtained combiuatively by means of two different type's gas-sensitive resistance. The method is based on the principle that the working current of the gas-sensitive resistance is a function of reductive gas types and their concentrations.
