几个辐射图解的比较

COMPARISON OF SEVERAL RADIATION CHARTS

中文摘要:

      本文讨论了八种辐射图解的基础方程和计算结果,对不同辐射图解的透射函数跟气压和温度的关系,以及对光谱重迭区内CO₂和水汽的处理也进行了研究,最后比较了不同辐射图解的大气发射能力曲线。通过上述讨论,初步分析了各辐射图解的优缺点和产生不同计算结果的原因。

英文摘要:

      In this work we have discussed the fundamental equations of eight radiation charts.The interrelations of transmission function with pressure and temperature were discussed.We not only investigated the problems of heat radiation which are affected by carbon dioxide and water vapour in spectral overlapping region, but also analysed the errors of carbon dioxide radiation of some charts.Finally, the comparison of various radiation charts for atmospheric emissivity has been made. According to this study, it is possible to find out the reason for the differences in the calculation results with these charts and to estimate,to a certain extent,the advantages and drawbacks of these charts.
