双光干涉原理在检测甲烷气体浓度中的应用

Application of the Principle of Two-beam Interference in the Monitoring of Concentration of Gaseous Methane

利用光的干涉原理给出了监测甲烷气体浓度的一种方法．该方法既简单又方便,而且便于实现条纹计算的自动化处理．

A convenient method for monhoring of concentration of gaseous methane by application of the principle of two-beam interference is studied. The result of interference can be analysed automstically.
