用离散座标求解输运方程的S_N方法是堆物理和堆屏蔽计算中常用的较精确方法,ANISN程序是国际上广泛使用的,用FORTRAN语言编写的计算中子和光子输运的一维S_N程序。它的计算结果通常可用为比较其它S_N计算的准则。该程序经引进,已
The S_N method for solving transport equations with discrete coordinates is a more accurate method commonly used in heap physics and heap shielding calculations. The ANISN program is widely used in the world. The one-dimensional S_N for calculating neutron and photon transport written in FORTRAN program. Its computational results are usually available as a guideline for comparing other S_N calculations. The program has been introduced, already
