摘要
对于半平面问题，在进行数值计算时，如果不考虑无限远处对近场的影响，则计算精度会受到一定的影响。本文在前人工作的基础上构造无限边界单元，可以在不增加大量单元的基础上考虑无限远处的影响，这样能更好地模拟实际问题，为数值计算带来方便和有效的数值结果。
In regard of the problems on semi plane, when the calculation of its numerical value proceeds, the calculation accuracy will come under influence if the effectiveness of the infinite far place on the nearby sites are not considered. Based on the working results gained by predecessors, an infinitely boundary element construction is proposed in the paper, with consideration taken of the influence upon the infinite far place, without increasing a large number of elements. By doing so ,much better modeling paractical problems can be carried out ,which will result in convenience and efficience in the calculation of the numerical value.
