为了研究扩展无网格伽辽金法（X-EFG）对实际问题的适用性，将X-EFG应用于复合介质材料的静电问题。数值实验表明，X-EFG得到的静电势在介质复合材料中是自然分布的，其数值解的精度与标准EFG（S-EFG）几乎相同。此外，X-EFG生成的线性系统的系数矩阵的条件数比S-EFG少得多。
To investigate applicability of the eXtended Element-Free Galerkin method (X-EFG) to realistic problems, the X-EFG has been applied to an electrostatic problem in a dielectric composite material. Numerical experiments show that the electrostatic potential obtained by the X-EFG is naturally distributed in the dielectric composite material, and the accuracy of the numerical solution obtained by the X-EFG is almost the same as that of the Standard EFG (S-EFG). In addition, the condition numbers of the coefficient matrices of the linear systems generated by the X-EFG are considerably less than those of the S-EFG.
