摘　　要：针对采用化学式碘发生器的氧碘激光器稳定出光时间较短的情况,通过热力学和化学动力学方面的实验和分析进行了化学式碘发生装置供碘稳定性的研究。分析了物料转化率和反应速率随反应初始温度及反应时间的变化,得到了固相产物的灰层扩散是该反应控制步骤的结论,明确了实验中CuI要大大过量,用氯气量控制碘量的原则,同时确定了适宜的起始反应温度。优化后,在近15s时间内碘流量变化小于15%,显示出了较好的供碘稳定性,此时CuI的转化率为23%。The experiments and analysis about thermodynamics and kinetics have been conducted to improve the stability of chemical iodine generator for COIL.The change of conversion rate and reaction velocity with reaction temperature and time was researched.The results show that the ash layer diffuseness of the solid production is the control procedure of reaction and the suitable temperature is about 410 K.They also indicate CuI should be excessive in experiments,and the iodine flow rate should be controlled by chlorine flow rate.The change of iodine flow rate is less than 15% in nearly 15 safter optimizing the generator structure and experimental condition.And the CuI conversion rate is 23%.
