摘　　要：为提高化学氧碘激光性能,分别使用-117℃乙醇、-110℃氟里昂和-45℃质量分数为50%过氧化氢冷射流进行单重态氧气流中的水汽脱除实验。实验结果表明:这3种冷射流的除水效果并不显著,乙醇基本上没有任何脱水效果,氟里昂和过氧化氢仅可以将水汽含量分别降低至原来的约1/5和1/4;乙醇和氟里昂因极易挥发而对气流产生严重干扰,并不适合用于除水;只有难挥发的过氧化氢才是合适的候选。To improve the performances of chemical oxygen iodine laser（COIL）,experiments were done for the removal of water vapor content in singlet oxygen gas flows by using-117 ℃ ethanol（C2H5OH）,-110 ℃ freon（CCl3F） and-45 ℃,50% hydrogen peroxide（H2O2） cold jets respectively.Experimental results show that dehydration effects of the three cold jets are not so remarkable： C2H5OH has scarcely any dehydration effect,and CCl3F and H2O2 can only reduce water vapor contents to about 1/5 and 1/4 of the initial values respectively.C2H5OH and CCl3F are so readily volatilized that they would produce severe interference in the gas flows and are not applicable to the removal of water vapor.Only the nonvolatile H2O2 is the suitable candidate.
