采用蒙特卡罗法获得了离散坐标方程的不含任何假散射的高精度解 ,其基本思路是 :当采用一个离散坐标格式来计算一个漫射表面的热辐射时 ,就意味着用有限个离散方向去“代表”2π立体空间上的无穷多个方向 .因此 ,不妨假定存在着这样一个虚拟表面 :该表面的确只沿着该离散坐标格式的离散方向上发射热辐射 ,并且在每个方向上的热流也完全遵循离散坐标方程 .然后将蒙特卡罗法应用于此虚拟表面 ,由此所获得的解即为此虚拟表面的高精度解 ,不言而喻它也等效于离散坐标方程的高精度解 .在此基础上 ,分析了离散坐标法的假散射对计算结果的影响
The Monte Carlo method is used to obtain a high-resolution solution of the discrete coordinate equation without any pseudo-scattering. The basic idea is that when a discrete coordinate format is used to calculate the thermal radiation of a diffuse surface, it means to use a finite number of discrete directions Go to “represent” an infinite number of directions in the 2π stereoscopic space, so it may be assumed that there is a virtual surface that emits thermal radiation only in the discrete direction of the discrete coordinate format, and that in each direction The heat flow also follows the discrete coordinate equation completely, and then the Monte-Carlo method is applied to the virtual surface, and the solution obtained is the high-precision solution of the virtual surface. It goes without saying that it is also equivalent to the discrete coordinate equation Based on this, the influence of the discrete scattering method on the calculation results is analyzed
