摘　　要：为提高化学氧碘激光的性能,用五氧化二磷(P2O5)和硫酸(H2SO4)射流进行了单重态氧气流中的水汽脱除实验。实验结果表明:在约4kPa压力、20m/s流速和5ms停留时间的气流状态下,P2O5和H2SO4射流可将水汽含量分别降低至原来的约1/5和1/16,发烟硫酸甚至可降至约原来的1/90,而且对单重态氧的猝灭很小。P2O5和H2SO4都是极佳的常温射流除水剂。To improve the per[ormances of chemical oxygen iodine laser （COIL）, experiments were conducted for the removal of water vapor in singlet oxygen gas flows by using phosphorous pentoxide （P2O5） and sulphurie acid （H2SO4） jets. Ex per/mental results show that P2O5 and H2 SO4 jets reduce water vapor content to about 1/5 and 1/16 of its initial value respective ly, for oleum even to about 1/90, in the gas flow state of the pressure of about 4 kPa, velocity of 20 m/s and resident time of 5 ms; moreover, their quenching effects on singlet oxygen are rather small. Both P2O5 and H2 SO4 are excellent ambient tempera ture-iet dehvdrating agents.
