摘　　要：将描述非灰气体辐射特性的指数宽带模型引入均匀离散射线法，推导了非灰气体参与介质条件下，辐射全交换面积的计算式，并计算了二维封闭体系的辐射全交换面积。结果表明。S\ The uniform deterministic discrete emission method and wide band model are combined to calculate the total radiant exchange areas for a two dimensional enclosure filled with nongray gas.The results show that the uniform discrete deterministic emission method can be used to a nongray medium.At the same samples the uniform discrete deterministic emission method is better than Monte Carlo method.
