【摘要】 考虑参与介质的散射作用,给出三维散射介质中辐射直接交换面积的广义对称性以及以形心距为线索的辐射直接交换面积的简化计算方法,模拟计算了含有散射介质的三维系统辐射直接交换面积.数值模拟结果表明,与忽略介质散射作用的简化描述相比,容积单元-容积单元的辐射直接交换面积增大,表面单元-表面单元的辐射直接交换面积降低.更多还原

【Abstract】 An effective calculation method has been proposed based on the principles of general symmetry of the matrix of direct exchange areas and the equal distances of the geographic center,which can avoid the huge calculation of the direct exchange areas in the regular 3-D system with scattering media.In comparision to the description neglecting the scattering effects of media,the numerical simulation results showed that the direct radiant exchange area between surface and surface zones decreases due to the weakened scattering effect of media,while the one between volume zones increases.更多还原
