The results indicate that the higherorderelement exhibits better convergence than the lower order element in all cases without imposition of natural boundary conditions.
结果表明，在所有情况下，与低阶元素相比，高阶元素均显出有较好的收敛性。

The stress fields of such structure around the opening were predicted using a three-dimensional, higher-order fast multipole boundary element method.
为精确模拟该结构的应力状况，该文提出一种三维高阶快速多极边界元法。
