摘　　要：针对我国当前煤矿瓦斯检测中存在的测量精度低、仪器寿命短等问题,提出了基于红外差分吸收法的煤矿瓦斯浓度检测方法。通过实验证明,该方法可以准确地测量出煤矿瓦斯浓度,而且由于光源采用了发光二极管,故使得仪器寿命大幅延长。In order to solve the problem of low accuracy and short life of equipment used in gas detection, this paper proposed a new method which used infrared differential absorption method to detect the concentration of gas and used LED as light sources. The experimental results show that the method can accurately measure the gas concentration. And using LED as light sources makes a substantial extension of equipment life.
