摘　　要：用宽带及其修正模型模拟非灰介质的辐射特性，并将它用于区域法模型，计算了非灰气体介质中表面—表面之间的辐射直接交换面积。结果表明：修正的宽带模型对气体辐射特性的描述是比较准确的。Wide band mold and its modification are used to simulate the radiative properties of non gray gases, and they are combined in zone method to calculate the surface surface radiative direct exchange areas for a non gray medium. Results show that the modified wide band model can successfully describe the properties of non gray gases, and can be easily combined with zone method.

关 键 词：宽带模型 辐射直接交换 面积 辐射传热
