| 摘 要： | 针对大气污染物之一的二氧化硫气体, 根据其吸收特性, 合理地选择激发波长, 从而避免了大气中其他气体的干扰, 采用Continuum Sunlite EX, 脉宽6 ns, 重复频率10 Hz的激光在实验室内模拟测量了污染气体二氧化硫的激光诱导荧光光谱, 分析计算了大气污染成分二氧化硫浓度. 研究表明, 激光诱导荧光方法可以用于大气中二氧化硫浓度的精确测量.

| Abstract: | The current laser detection method to measure the concentration of sulfur dioxide was discussed. Different concentrations of sulfur dioxide were measured with the technique of laser-induced fluorescence (LIF). The results show that the method mentioned here can be used to measure the concentration of sulfur dioxide in the atmosphere. |
