| 摘 要： | 本文介绍了一侧为半透明、另一侧为非透明界面时一维半透明介质的辐射强度计算式。采用辐射与导热复合换热模型计算半透明介质内温度场。利用已知的温度场求半透明介质的辐射强度一正问题计算。将此辐射强度代入辐射反问题计算模型，引入测量误差，采用Ｃｈａｈｉｎｅ方法及演半透明介质内温度场一反问题计算。数值模拟表明，本文所采用的辐射反演法具有较高的精度及稳定性。

| Abstract: | An one dimensional radiation intensity equation in semi-transparent medium is introduced with one side semi-transparent and the other opaque. The temperature field in semi-transparent medium is analyzed with the aid of combined radiation-conduction model.The direct problem is to calculate radiative intensities in semi-transparent medium from known temperature field. Inserting these radiation intensities plus some measurement errors in inverse radiation model to estimate the temperature field by use of the Chahine method is the inverse problem. Numerical simulation shows this inverse radiation method has better accuracy and stability. |
