    摘要
  • 摘要: 为了实现痕量气体在线测量与分析，设计了光纤环路光腔衰荡多组分气体浓度在线测量系统；基于非线性光腔衰荡技术，利用所设计的系统对气体浓度在线测量并进行了实验分析；得出了同种气体不同浓度时光的吸收程度随时间变化的规律和1ppb的分辨率。实验表明该方法对痕量气体的在线测量是有效的。
    Abstract: In order to realize the trace gas concentration on-line measurement and analysis，a multi-type gas concentration on-line measurement system based on fiber-circled cavity ring-down method was designed and developed. Based on the nonlinear optical cavity ring-down technology, the experimental analysis of the gas concentration in-situ measurement with such system was performed. The gas-to-light absorption characteristics of the same gas with different concentrations changed with time and their relationship was given. The resolution of concentration measurement reaches 1ppb. The experiment proves that the system can be used to measure trace gas concentration effectively.
