| 摘 要： | 本文介绍了一般等效均匀化理论（Ｇ．Ｅ．Ｔ）及其在格林函数方法中的应用，并改编了二维节块格林函数方法程序（ＮＧＦＭ）。为了验证程序的正确性，对ＨＥＮＲＹ－ＷＯＲＬＥＹ沸水堆基准题作了计算。结果表明，在节块方法中采用一般等效均匀化理论可以有效地提高计算精度，极大地改善由于组件均匀化引起的误差。

| Abstract: | In this paper, the general equivalent theory on assembly homogenization (G. E. T.) isintroduced and applied to the nodal Green's function method (NGFM) for the numerical solution of neutron diffusion equations. The Henry-Worley BWR Benchmark problem has been calculated for verification. The numerical results demostrate that the application of G. E. T.significantly improved the accuracy of the core POwer distribution in the nodal method. |
