摘要： 采用蒙特卡罗（ＭｏｎｔｅＣａｒｌｏ）方法，进行了平板、半球面、抛物面的地球反照角系数和地球红外角系数计算，通过与文献数据的比较，证明了由此方法所编程序的可靠性和实用性。利用这种方法，可以计算空间任意形状凸表面的轨道空间外热流。

Abstract: On the basis of Monte Carlo method,have the results of albedo and infrared view factors of flat plate, hemispherical surface and parabolic surface. Compared with the data of view factors handbook t17, the results show that the program based on Monte Carlo method can be used to calculate orbital heat fluxes of arbitrary shaped convex surfaces of a spacecraft practically and reliably.
