| 摘 要： | 实验研究了条纹放电的明条纹和暗条纹中汞原子的谱线强度，然后建立汞原子放电的八能级模型，从求解速率方程得到条纹中各种粒子的浓度和电子温度，从而求得了汞可见谱线强度，计算结果和实验符合较好，计算还表明暗纹之间的电子温度判别较大，在明条纹中Tc=153000K，暗条级中Tc=14400K，条纹的明暗判别主要是电子温度不同造成的。

| Abstract: | The spectrum radiance in bright and dark region of striation discharge is studied experimentally.Then a mercury discharge model with eight energy levels is set up.The solutions of rate equations give the electron temperature,electron density from which the mercury visible spectrum line luminance is obtained.The calculation results are in reasonable agreement with experimental measurement.The electron temperature in bright region of striations is different from that in dark region which is 15 300 K and 14 400 K respectively.The radiance of striation is mainly determined by electron temperature. |
