| 摘 要： | 给出了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浓度C随时间变化的曲线,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.

| Abstract: | From the formula of reaction exothermic rate, the differential equation of C(t) in the closed chamber test is given. From the solution of C(t), it shows that the closed tested chamber is a very slowly precess in concentration attenuation and the error caused by C can be ignored. |
