摘　　要：构建基于随机共振的气敏传感检测系统,采用双层随机共振算法,根据信噪比最大值之间的差值检测气体浓度,可以准确检测瓦斯气体的浓度,为瓦斯检测提供一种新方法。Builds up a gas-sensing detection system based on the stochastic resonance phenomenon. Using double-layer stochastic resonance algorithm,and detecting the gas concentration by maximum difference of signalto-noise ratio,might accurately detect the gas concentration in the environment. The study provides a new way for gas detection.
