摘要 针对目前气体辐射特性计算模型存在的不完善因素 ,本文通过考虑波长、温度、总压以及气体成份对总辐射特性的影响 ,提出用谱线增宽程度和指数宽带参数对现有的混合气体谱带模型进行修正 .并从两个方面对模型的正确性进行了验证 .结果表明 。 Bearing in mind the imperfections of computational model for Non gray gases radiation properties, the modification of a revised band model is proposed to take into consideration, the effect of wavelength, temperature, total pressure and ingredients of gases mixture, and Line broadening degree and index band parameters are presented to justify the computer code. The results obtained by the present method are in good agreement with the experimental results.
