| 摘 要： | 通过半解析法求解由孤立点源产生的未碰撞中子源项，进而求出首次碰撞源分布，以将孤立的源分布到更广的范围中，从而减轻由离散纵标法计算产生的射线效应。编制了适应于三维离散纵标计算程序CTDOS的射线效应减轻程序REM3D，与Kobayashi三维基准题的结果进行比对，证明了射线效应减弱的正确性与本程序的可行性。

| Abstract: | The uncollision neutron source was calculated from isolated source by semi-analytic method, and distribution of first collision source for the models was achieved. In this way, the theory to mitigate ray effect of SN theory by distributing the isolated source into range area was established, and the corresponding code REM3D for three-dimensional discrete ordinate code CTDOS was also developed. The results on Kobayashi benchmark indicate that this theory is appropriate and this program is correct. |
