摘要 提出了一种在网格内部采用线性源分布的特征线方法,并且编写了线性源特征线方法程序TCM_L。数值计算结果表明,线性源特征线方法的计算精度高于平源特征线方法和简化线性特征线格式SLC;使用大网格计算的线性源特征线方法在保证计算精度的同时可以节省大量的存储空间和计算时间。 A method of Characteristics with Linear Source Approximation（LSA） is proposed in this paper,and the corresponding code TCM_L is developed.Numerical results show that the LSA MOC can get more accurate results than the Flat Source Approximation（FSA） MOC and SLC MOC,and the LSA MOC code can use less storage and shorter computing time when using large meshes.
