The boundary integral equation in homogeneous media was dispersed into algebraic equations through the use of spline function.

采用样条插值函数将均匀介质的边界积分方程离散为代数方程组。

Then the displacement field in homogeneous medium is considered the result of the first iteration, and the displacement field is solved by this integral equation.

然后，在均匀介质中的位移场被认为是在第一次迭代的结果，和由这个积分方程求解的位移场。

It is proved that if the medium is piecewisely homogeneous, the solution of the differential -integral equation satisfies the boundary conditions on boundaries between different media.

证明了在介质为分区均匀的条件下，这个微分-积分方程的解满足不同介质边界面的边界条件。
