余数法 meaning in English

method of residues

Then three schemes of the preconditioned sparse matrix canonical grid ( p - smcg ) method are presented and discussed . the sparse matrix canonical grid method is applied to analyze electromagnetic scattering from three - dimensional random dielectric scatterers in conjunction with the generalized minimal residual ( gmres ) method . in the end , these four schemes are applied to analyze electromagnetic scattering from three - dimensional random dielectric scatterers
论文首先运用smcg方法对随机分布三维介质目标的电磁散射问题进行较为全面的分析和讨论，然后讨论了如何对smcg方法进行预处理，提出了预处理smcg方法的三种方案，接下来又讨论了将smcg方法和广义最小余数法( gmres )结合起来的方案，最后应用上面提出的四种方案对多个随机分布三维介质目标的电磁散射问题进行了分析。
