摘　　要：提出了一种基于相关光谱法的甲烷检测方案,在传统相关光谱法和差分吸收技术的检测理论的基础上,综合两者的优点提出了一种新的实现方案。合理的选择实验器材,构建了一个新的光纤甲烷检测系统。该系统不仅消除了待测气体中干扰气体引起的光强波动,而且也消除了周围环境的影响和光源光谱波动引起的干扰。A method based on correlation spectroscopy and single-wavelength differential absorption technique of methane detection were investigated.A new implementation was proposed which combines the advantages of the traditional correlation spectroscopy and differential absorption technology.A new fiber-optic methane direction system was built up with the test equipments properly chosen.The system not only eliminates the fluctuations in light intensity due to the interference gas in the test gas,but also eliminates the impact of the surrounding environment and light source spectrum.
