摘要
给出气敏元件反应放热率Prea的公式,并由此给出在闭室测试中气体浓度C随时间变化的微分方程.通过求解微分方程给出的浓度C随时间变化曲线,表明了气体的浓度衰减很慢,而由此带来的误差一般可以忽略.
The formula of reaction exothermic rate Prea of sensors and the differential equation of closed test chamber gas concentration C varies with t is given. From the solution of differential equation C-t curve, it is proved that the relaxation of gas concentration is rather slow and the errors of clssed chember test can be neglected.
