英文摘要：

Based on the sensitivity of catalytic sensor is different in different temperatures , a new method of analyzing flammable gases with a single catalytic sensor based on thermostatic detection and RBF neural network theory was put forward. A mathematic model of analyzing the diversiform inflammable gases was erected by RBF neural network of dynamic learning algorithm. By the experiment of mixed gases such as firedamp, carbon monoxide and hydrogen, the result showed the possibility to analyze mixed inflammable gases by one catalytic sensor.
