| 摘 要： | 在主、副气流流量不变的情况下，仅改变氧碘化学激光器中碘喷孔的位置，数值模拟了其混合气体流场特性和小信号增益分布等的变化。计算结果表明，碘喷孔在喷管叶片上的位置沿气流方向往下游移动，混合状况变差，光腔中小信号增益降低，输出功率减小，饱和光强沿气流方向的衰减变得平缓。

| Abstract: | The mixed flowfield performance, small signal gain distribution, and output power are numerically simulated by changing the position of the iodine injector with constant primary and secondary flowrate. This study shows that the mixed flowfield results worse, the magnitude of small signal gain becomes smaller, the output power gets lower, and the decay of laser intensity vs x goes slower while the position of the iodine injector moves forward alone the flow direction. |

| Keywords: | numerical simulation position of the iodine injector small signal gain |
