| 摘 要： | 建立了谱线增益系数与温度、粒子数分布之间及谱线增益系数与谱线强度之间的关系式，对一台燃烧驱动DF激光器的发射光谱进行了测量，利用发射光谱数据计算得到光腔温度为381.4 K，分布在振动态能级1与0，振动能级2与1，振动能级3与2的粒子数之比分别为0.60～0.62, 0.676 4, 0.71～0.74。

| Abstract: | The relational expressions between gain coefficient, intensity of spectral lines and the temperature, population distribution in optical cavity were established, and the emission spectrum of a combustion-driven DF chemical laser was measured, calculation based on spectral data showed that the temperature in optical cavity was 381.4 K, the ratio of population in ν=1 vibration level to ν=0 level, population in ν=2 level to ν=1 level, and population in ν=3 level to ν=2 level were 0.60～0.62, 0.676 4, 0.71～0.74, respectively. |
