【Abstract】 The stability of a series of micro hotplate based gas sensors were investigated and the descriptive methods were discussed in focus. From the point of statistics, the general feature parameters to denote gas sensors’ stability were compared and an optimal parameter set was extracted. The variation coefficient of parameters was adopted to describe the stability. By using this approach, the influences of preheating time on gas sensors’ stability were investigated.更多还原
