Development of smell discrimination sensor and application for local

通过对半导体气敏元件瞬态响应模型的计算，得到了半导体气敏元件瞬态响应与激活能的关系。用SnO2团簇的分子轨道计算方法估算了活化能。结果表明，该传感器的瞬态响应梯度与激活能成正比。利用该关系式可以实现气体识别。该传感器被应用于干洗和豆源生产过程。通过半导体气体传感器监测这些过程将是可能的。

Activation energy dependence of transient response of semiconductor gas sensor was found from calculations by model of transient response of the sensor. The activation energies were estimated from molecular orbital calculation using SnO2 cluster. It was found out that gradient of the transient response of the sensor was proportional to the activation energy. Gas discrimination will realize using this relation. The sensor was applied to dry cleaning and soy source production processes. Monitoring of these processes will be possible by semiconductor gas sensor.
