摘要: 在激光X光转换规律的研究中必须认真讨论辐射场的计算。本文提出了解电子,离子,光子三温相脱离的能量方程的两种差分格式,即隐式格式的整体迭代求解和分裂格式解法,文中介绍了能量交换项与其它项分开计算的分步方法,并考察了对温度变化的影响。数值计算表明结果是正确有效的

关键词: 激光转换X光, 三温方程, 能量交换项, 分裂格式

Abstract: In order to study physical laws related to laser X-ray conversion, two kinds of difference schemes, i.e.implicit method and splitting scheme, for solving electronic、ionic and photonic temperature equations are presented. The splitting scheme separating the energy exchange term from other terms is introduced and its influence on temperature is also investigated.

Key words: laser x-ray conversion, three temperature equations, energy exchange term, splitting scheme
