摘要

基于气体的红外吸收原理

研究了一种能在复杂环境下测量甲烷气体体积分数的新方法。这种方法可以有效地减小由于光源的不稳定、环境的变化而引起的测量误差。在这种测量方法中设计了一条参考测量光路

此参考测量光路和测量光路同时随环境的变化而变化

通过对待测量气体光路与参考气体测量光路作对比而得出较为准确的待测甲烷气体体积分数。

Abstract

Based on the infrared absorption mechanism of gas

a new method for measuring methane volume fraction under complex environment.This method can effectively reduce the measurement error caused by the instability of light source and environmental changes.A reference measurement optical path is designed in this measurement method.Both the reference optical path and measuring optical path change with environmental change.More accurate analyte methane gas volume fraction can be derived by the comparison of reference optical path with measuring optical path.
