摘　　要：提出了求解二维梯度折射率介质内各向异性散射辐射传递的积分矩方法。通过散射相函数的处理和辐射强度矩的定义,将原始的积分微分控制方程转化为微分方程,并用积分方法求解。将积分矩方法的计算结果和文献中的数据进行了比较,两者符合得很好。The integral moment method is presented to solve radiative heat transfer in two dimensional anisotropic medium with graded index.Original integral-differential governing equation is transformed into differential equation,which is solved by using integral method,through deduction of the scattering phase function and definition of the radiative intensity moment.The results of present method are compared with those in references and it can be seen that they have a good agreement.
