用几何光学方法模拟黑体,得到的数学模拟式,经典,严密,精确,适用,黑体的物理概念明晰。适合于几何光学方法模拟的黑体,其腔体属光壁腔体。这种腔体的腔壁之比辐射率ε_0极低,一般仅0.1左右,但因方法得当,使模拟黑体具有极强的腔体效应,结果亦能使腔体之比辐射率ε近于黑体的1。图1所示腔体是一种典型光壁黑体腔,其ε_0=0.16,ε=0.99999。 Geometry optics method is used to simulate the blackbody, and the mathematical concepts of the classical, rigorous, accurate, applicable and bold are clear. Suitable for the geometric optics method of the blackbody, the cavity is a light wall cavity. The cavity wall emissivity ratio ε_0 extremely low, usually only about 0.1, but due to the method so that the simulated blackbody has a very strong cavity effect, the result can also make the cavity emissivity ε near the black body 1. The cavity shown in Figure 1 is a typical optical wall blackbody cavity with ε_0 = 0.16 and ε = 0.99999.
