Therefore the generalized numerical quadrature formula with the single node is deduced naturally.

而且，由此自然地推导出单节点数值积分公式。

In this paper, a new unconventional numerical quadrature with fewer node values is established based on a special nonconforming rectangular finite element.

利用一个特殊非协调矩形元导出了一个新的使用节点少而代数精度高的非常规数值积分公式。
