测量了在实验室清洁空气中加入几种气体（氢气、丙烷、异丙醇和一氧化碳）及其双组分混合物时，热循环Figaro #813气体传感器的电导随时间的响应。输出传感器信号被表示为两个或更多个高斯函数的线性组合。发现这些函数的极大值的位置是气体的特征，为选择性检测易燃或有毒气体提供了一个很好的判据。讨论了高斯函数解卷积法在双组分混合气体定量分析中的应用及其局限性。
The conductance versus time responses of a thermally cycled Figaro #813 gas sensor have been measured for clean laboratory air with the addition of several gases (hydrogen, propane, isopropanol and carbon monoxide) and their bicomponent mixtures. Output sensor signals are represented as linear combinations of two or more Gaussian functions. It is found that the positions of the maxima of these functions are characteristic features of a gas, providing a good criterion for the selective detection of inflammable or poisonous gases. The potential application of sensor signal deconvolution with Gaussian functions for quantitative analysis of two-component gas mixtures and its limitations are demonstrated.
