对于粘性流动在拐角处解的行为，木文提出了一种积分方法．它是用算子的本征函数展开代替离散化，得到一个部分解析解．与边界无法相比，解的精度得到提高．
For the behavior of viscous flow at the corner of the solution, a method of integration is proposed by Wood. It replaces the discretization with the eigenfunction of the operator to obtain a partial analytical solution. Compared with the boundary can not be compared, the accuracy of the solution is improved.
