| 摘要: |
| 使用蒙特卡罗直接模拟法模拟了 300keV 氚束流 T(d，n)4He 中子源发出的中子在球壳屏蔽体介质铁中的输运规律。分析了不同介质厚度的铁对中子的反射性质和吸收性质，这些解释和分析对快中子球壳屏蔽参数的选取具有重要价值。 |

| Abstract: |
| With the Monte Carlo direct simulation method，we simulate the neutron tracks or histories by means of the random nature of the neutron interactions with the medium of shield which is a shell of the sphere made of Iron，and neutrons. are produced by the T(d，n)4He reaction with 300 keV deuteron beam energy. The reflective properties and absorptive properties of neutrons are analysed in the different thickness of the medium of Iron. These explanations and analyses of results have an important value in choosing shield parameters of spheric shell of fast neutron. |
