摘要: 比较了节块展开法(NEM)、节块格林函数法(NGFM)和节块傅立叶展开法(NFEM)的偏中子通量展开技术,证明了NFEM的精度高于任何有限阶NEM,而与NGFM相当.

关键词: 节块展开法, 节块格林函数法, 节块傅立叶展开法, 展开技术

Abstract: The partial flux expansion techniques are compared and evaluated among the nodal expansion method (NEM),the nodal Green's function method (NGFM),and the nodal Fourier expansion method (NFEM).The numerical results and analyses confirm that the accuracy of NFEM is higher than any finite-order NEM and is comparable with NGFM.

Key words: nodal expansion method, nodal Green's function method, nodal Fourier expansion method, expansion technique
