论文摘要
对于血浆密度的静水体剖面,考虑了自我发射氢等热气氛中辐射的热化问题。使用定义给定频率光子的热深度的概率方法。定量结论是关于可以将辐射视为热元频率的光学深度值的值得出的。辐射转移方程的分析和数值解确认了获得的结果。计算了在冷的非磁化和磁化等离子体中,由于单个相互作用引起的光子免费吸收概率的频率依赖性。
The problem of thermalization of radiation within a self-emitting hydrogen isothermal atmosphere is considered for the case of a hydrostatic profile of the plasma density. The probabilistic approach to define the thermalization depth for the photon of a given frequency is used. Quantitative conclusions are made on the value of the optical depth at which the radiation can be viewed as thermalized up to a given frequency. The analytical and numerical solutions of the radiative transfer equation confirm the obtained results. The frequency dependencies of the probability of free-free absorption of a photon due to single interaction in a cold nonmagnetized and magnetized plasma are calculated.
