光干涉法实现CH_4浓度的直读式测量

Realization of the Measurement Directly Reading the CH 4 Concentration Using the Optical Interferometry

讨论了如何利用现代电子技术把矿用光干涉ＣＨ４检测仪变成为直读式测量仪表的原理和设计方法，从而使老仪表焕发青春。

It is discussed in this paper the principle and design method of the directly reading instrument and how to use the modern electronic technique into the CH 4 mike interferometer.
