摘　　要：运用矩阵变换方法对已有的无限长矩形条件下的扩散方程的解析解进行了化简,大大提高了计算机模拟的速度。利用给定的人体前臂组织的典型光学参数,给出了扩散方程解析解的模拟计算结果。分析了介质的基本光学特性参数对漫射光子密度的影响,在验证已有的理论基础上,发现该模型下的解析解不适用于漫射系数D较大的情况。The analysis resolution of the diffusion equation under the condition, which is infinite cube, was predigested by using matrix transform method. And the simulation velocity was improved much. Using the presented typical optical parameter of human being＇s forearm tissue, the simulation result of the analysis resolution of the diffusion equation was shown. The influences of the medium＇s basic optical parameter on the photon density wave were analyzed. These results validate the theory that have been provided, and if was found that the analysis resolution is not applicable for the conditions that diffusion coefficient is large.
