fictitious boundary meaning in Chinese
假想边界
Examples
- The fbc for connecting the subdomains on fictitious boundary is developed according to the actual field distribution in the waveguide to ensure the propagation of waves between adjacent subdomains . the relaxed algorithm is introduced to improve the iterative convergence
文中从实际场分布出发，在划分区域的虚拟边界上给出了连接子域的吸收虚拟边界条件，并通过引入松弛算法，构建了一种能够用于分析波导问题的松弛迭代区域分解法。 - Secondly , the physical nature of divergence of iterative ddm based on the schwarz alternating method in treating waveguide problems is given in this paper . also an absorbing fictitious boundary condition ( fbc ) is presented to generate an iterative ddm for waveguide problems
其次，针对helmholtz方程微分算子的系数矩阵非正定，基于schwarz交替法的迭代区域分解法，在分析波导问题时迭代不收敛的困难，探讨了产生这一问题的物理本质。 - So it is necessary to reflect the inner reality physical field ' s numerical number analogy method to analysis and improve the magnetic field and the computing accuracy of the cable ' s eddy - current detection . Ｔ his affords helping for the researching of biased cable instrument in the future . first open domain electric magnetic problem ' s breaking method is done with , which supposing fictitious boundary far away from the region . second breaking the infinite region into the finite region and supposing the electric magnetic is too small to be ignored
通过采用目前处理开域电磁场问题的截断法，人为地设定一个远离待求区域的虚拟边界，将无限区域截断为有限区域，且认为在该边界外面的电磁场已衰减得足够小，小到可以忽略不计，从而令边界上的电磁场场量为零，在此有限区域内采用较为成熟的Ａ ， Ａ法，并且并入库仑规范建立数学模型。
