摘要
详述了气体浓度检测的原理:朗伯-比尔吸收定律和差分吸收技术,并结合笔者设计的红外甲烷检测仪对气体测量仪的结构进行了详细介绍。
The characteristics of infrared absorption spectroscopy are described briefly and the principles of gas monitoring based on Lambert-Beer law and differential absorption are stated in detail. A portable infrared methane monitor has been designed, by which the structure of the gas monitor is also introduced.
