电激励O2（1△g）发生器的理论模拟研究

 建立了基于分子反应动力学的氧等离子体化学反应模型，该模型包括了电子与氧分子，以及氧原子与氧分子的碰撞反应过程。利用反应动力学理论计算并讨论了电激励O₂(¹△)发生器的放电参数，发现电子能量应小于2.5eV。电子浓度对O₂(¹△)产率的影响不大，当放电压力与气体线流速一定时，存在最佳的电子平均能量。     

横向射流式单重态氧发生器的性能实验研究

 对氧碘化学激光器的单重态氧发生器（SOG）进行了改进，采用横向射流方式，并对该横向射流式单重态氧发生器的性能进行了检测。实验中过氧化氢碱溶液温度控制在－16℃左右,氯气流量为530mmol/s，He与氯气的流量比为3;采用PS法测量单重态氧分子的产率,吸收法测量氯气的利用率和相对水含量。得出如下结论:在不使用冷阱和分离器的情况下，最高单重态氧分子产率达到58%, 氯气利用率在80%以上,相对水含量小于等于0.5;气体达到最大流量时,发生器仍然能稳定地工作。
