摘要: 介绍了差分吸收激光雷达测量大气中物质成份及浓度的测量原理，并利用差分吸收激光雷达测量了3.5 km内NO2的浓度分布，测量结果表明，使用双通道可调谐的Ti:Sapphire激光器的一组波长（448.2 nm和446.8 nm）可以获得比较精确的NO2的浓度随距离的分布。

Abstract: Measurement principle of ingredient and concentration of matter with difference absorption lidar (DIAL) is introduced. The distribution of NO2 concentration within 3.5 km range is measured with the DIAL. The result shows that very accurate concentration distance distribution of NO2 can be acquired by use of two wavelength (448.2 nm and 446.8 nm) of wavelength tunable Ti:sapphire laser ． -
