The required porosities for various cases were obtained through varying the diameter of holes and spacing among the holes 各物理模型通过改变气膜孔径大小和孔间距得到不同的孔阵排列疏密度。
The computational results show that to a certain extent the denser of the distribution of the holes , the higher of the cooling effectiveness 计算结果显示:在一定的范围内,孔阵排列的疏密度越大,冷却效果越好。
Finally , a multi - resolution reconstruction algorithm was proposed for optical tomography . in this algorithm , the delaunay triangulation rules are first used in the generation of the triangular mesh with 该方法首先根据图像的先验信息,利用delaunay三角剖分规则,在整个成像区域形成疏密度不等的网格划分,然后在此网格上实现ot图像的多分辨率重建。
