调和算子 meaning in English

laplacian

In this paper , firstly we present some results about of conventional bem , and multiple reciprocity method ( mrm ) for solving dynamics response of viscoelastic thin plate is given the whole plane expression and boundary integral equation for mrm , next we prove that the solution of the boundary integral equation obtained by mrm is the same as the one derived from the conventional fundamental solution of boundary value problem
本文首先给出了常规边界元方法的一些结果及在laplace变换区域中得到了由重调和算子基本解序列给出了粘弹性薄板动力响应问题的多重互易法( mrm方法) 。并对粘弹性薄板的动力响应问题的mrm方法给出了收敛性分析，证明了mrm方法导出的边界积分方程的解与边值问题基本解导出的常规边界方程的解是相同的。
