摘要: 氧碘化学激光中的水汽对其运行和性能有着重要的影响。建立了考虑淬灭的单重态氧产额和变截面定常一维流的方程组，编制了程序，采用Radicl的参数进行了计算，研究了碘离解和淬灭对氧碘化学激光气体流动特性的影响，初步分析了变截面的作用和设计考虑。Abstract: The water vapor has great influence on the performance of a chemical oxygeniodine laser. The equations for the O2(1Δ) yield and steady onedimensional flow with area change are set up to take into account the quenching. The code is made to calculate the flow properties of the Radicl device. The effects of iodine dissociation and quenching on the flow properties of a chemical oxygeniodine laser are studied theoretically. The role of area change and the factors in its design are analyzed.
