摘要： 推导了空间任意形状凹面和相互可视表面的地球红外角系数φ３和地球反照角系数φ２的计算公式３并运用ＭｏｎｔｅＣａｒｌｏ法对半球凹面、抛物凹面、两相互可视的直角平板、平板表面外凸出圆柱表面的地球反照角系数和地球红外角系数进行了计算。运用这种方法，可以计算任意形状凹面和相互可视表面的φ２、φ３．

Abstract: ormulas for calculating albedo Yiew factors φ2, and infrared view factors φ3, of arbitrary concave surfaces and mutually visible surfaces have been devised, and on the basis of Monte Carlo Method, the factors of various surfaces such as hemispheric concave surface,parabolic concave surface, two mutually visible and vertical flat plates and outer cylinder surface on the bottom of which there is a flat plate, haye been calculated.The results shows albedo and infrared view factors of that kind of shapes can be calculated practically by using above method.
