| 摘 要： | 从辐射传输最基本的原理出发，给出了描述辐射传热的一个控制微分方程，该方程克服了目前用来求解辐射传热所用方法的一些缺陷，反映了辐射传热空间全方位性的特点，而且利用该方法求解辐射传热，大大节省了计算机的内存及时间，提高了计算精度。十分容易与其它传输方程耦合在一起进行数值求解。

| Abstract: | On the basis of the fundamental principle of heat transfer by radiation,a kind of control differential equation describing heat transfer by radiation is given. It overcomes some faults of the present methods used to solve heat transfer by radiation ,and reveal the three dimensional characteristic features of radiation process. When the equation is used to solve radiative transport problem,it can save a lot of computer memory,CPU time and improve calculating precision. It is easily coupled to other transport equations to get numerical solution. |
