提出了一种基于动态非线性响应的新型气敏系统，用于评价混合气体对传感器响应的影响。对半导体气体传感器施加正弦温度扰动，并利用快速傅里叶变换（FFT）分析了扰动后传感器的电导。传感器的响应，其特征性地改变取决于气体混合物的组成，可以被分为三种类型（增强，抑制，和优先响应）的混合物。为了监测气体反应的进程，通过气相色谱法分析样品气体。通过考虑气体分子在半导体表面上的动力学，从理论上模拟了共存对气体混合物响应的影响。
A novel gas-sensing system based on a dynamic nonlinear response is reported to evaluate the effect of gaseous mixtures on the sensor response. A sinusoidal temperature perturbation was applied to a semiconductor gas sensor and the resulting conductance of the sensor was analyzed by fast Fourier transformation (FFT). The sensor response, which changed characteristically depending on the composition of the gaseous mixture, could be classified into three types (enhanced, suppressed, and preferential responses) by the mixture. To monitor the progress of the reaction of gases, the sample gas was analyzed by gas chromatography. The coexistent effect on the response to gaseous mixtures was theoretically simulated by considering the kinetics of gas molecules on the semiconductor surface.
