| 摘要: |
| 本文试图通过对快中子在氕化锂球中产氚率的计算来验证自行制作的18群常数的合理性和正确性。利用改进迁移近似方程和与之配套的18群中子群常数对两种模型中快中子的产氚率的计算表明，本文的计算结果在 3% 的精度内与其他研究者用不同的中子输运方程和不同的群常数对同样模型中的中子造氚率的计算结果符合。这说明改进迁移近似方程可以较好地描述快中子在轻材料中的输运行为，我们制作的与之配套的18群中子群常数是合理的，可信的。 |

| Abstract: |
| Using the modified transport approximation，the authors calculated and obtained 18-group neutron constants. In this paper，the authors try to examine the validity of these 18-group neutron constants by calculating the Tritium production rate of fast neutron in LID spheres. The modified transport approximation equation and its matched 18-group neutron constants are used to calculate the Tritium production rate of fast neutrons in two different models. The results are in good agreement with those obtaind by other authors using different transport equation and group constants，the relative errors are within 3%. The calculatied results and the comparison show that the modified transport approximation equation and its matched 18-group neutron constants can be used to describe the transport behavior of fast neutrons in light material，and the 18-group neutron constants obtained by the authors are reliable and rational. |
