1) near-field preconditioner
近场预条件
1.
Based on the "physical neighbor",a novel near-field preconditioner is proposed which improves greatly the convergence of BiCGStab(l).
为了在有限计算机资源条件下快速分析电大平台中的天线辐射特性,基于混合场积分方程实现了自动分层的多层快速多极子方法,采用结合GMRES(l)和BiCG优点的BiCGStab(l)进行求解,给出了一种新的基于"物理邻居"的近场预条件技术,该预条件能将矩量法单元之间的主要作用量考虑在内,有效提高了BiCGStab(l)的收敛速度。
2) the near-field preconditioner
近场预条件技术
1.
In this paper, the near-field preconditioner and incomplete LU (ILU) preconditioner are adopted to dramatically reduce the iteration count of the iterative solvers for solving the sparse matrix equations, arising from the MOT scheme of the time-domain integral equations.
本文将近场预条件技术和不完全LU分解(ILU)预条件技术用于时域积分方程时间步进算法。
5) Prediction of Near-Field
近场预测
6) near-axial condition
近轴条件
1.
In this paper,we analyse the interference of two light waves,which points out that the near-axial condition is very important,and prove that this condition has a good result in practice.
在分析双光束干涉时,近轴条件是一个很重要的前提条件。
