摘　　要：对某吸气/喷气叶栅的复杂的多联通域边界,采用孔斯双参数样条曲面模型,通过一维问题边界条件控制疏密度,选择合理的参数来强调正交性;分别在双参数域和绝对坐标系下求解微分方程,得到二维、三维网格。应用上述方法,为某叶栅叶片前缘和端壁开多排孔方案生成了三维贴体网格,获得了理想的效果。The gr/d orthogonulity was emphasized using the model of Coons two -parameter spline surface, controlling the grid density with 1D problem boundary condition and selecting reasonable parameters for the complicated multiply connected domain boundaries of cooling/bleed cascades. The 2D and 3D gr/ds were obtained by solutions of differentiating equation in the two -parameter region and absolute coordinate system respectively. It was reasonable that 3D body -fitted grids were generated by using this method for the project of opening multi - row holes on the leading edge and endwall. The quality of the computation grid was reasonable.
