摘　　要：水汽的含量是化学法单重态氧发生器（ＳＯＧ）的重要性能参数之一，因为它不仅对Ｏ＿２（￣１△）有猝灭作用，而且在氧碘化学激光器（ＣＯＩＬ）光腔中对Ｉ￣＊也有严重猝灭作用。因此测控ＳＯＧ出口处的水汽含量有重要意义。本实验采用光谱强度比较法测量ＳＯＧ中的水汽含量，利用ＯＭＡ－３的二维扫描积累功能，可对不同测点的光谱进行同时扫描积累，从而可以对ＳＯＧ的数个测点同时进行水汽含量测定。测试精度可达±１０％。Water vapor content is one of the important parameter of a Sin-glet Oxygen Generator (SOG) in researching of ChemicaI Oxygen-Iodine Laser(COIL).The water vapor will not only quench the O_2(￣1△),but also it will seriously quench the exited I￣* in COIL cavity. Evidently, the water vapor content at the exit of SOG must be measured and controlled. A spectrometric method can successfully meas-ure the water vapor content in SOG by using the special function of OMA-3(optical multichannel analyzer) to finish scanning and accumulating for spectra in differ-ent measuring points at the same time. The measuring precision is about ±10%.
