摘要
对计算等离子体的光辐射不透明度所涉及到的一些物理问题进行了介绍与讨论 ,重点放在束缚 -束缚谱线跃迁与束缚 -自由吸收及自电离共振引起的谱线展宽等物理过程。由于束缚 -束缚谱线吸收中涉及到谱线的各种增宽机制 ,我们对此也进行了讨论。在此基础上系统介绍了使用细致谱项模型计算等离子体的不透明度的理论研究现状 ,并结合涉及到的实验研究结果 ,对理论结果进行了检验。特别是结合我们最近的研究进展 。
The physical problems concerned with the calculations of the radiative opacities of high temperature plasmas are presented, the emphasis being placed on such atomic processes as bound bound transitions, bound free transitions and the autoionization resonance broadening. Various broadening mechanisms related to the calculations of the bound bound absorption are also discussed. The theories of the calculations of the radiative opacities of high temperature plasmas using detailed term accounting (DTA) approximation have been introduced. The theoretical results are compared with the experiments. Emphasis is placed on discussing some of the results we have obtained recently.
