曲面边界 meaning in English
surf edge
surface edge
Examples
- Tangency is controlled by the first two control points from a surface boundary , assuming that these points lie in one line
相切是由曲面边界的最初两个控制点控制的（假设这些点在一条线上） 。 - Method of edge curve replacement is used to reach gc0 connection of two surface . method same as bezier gc1 connection is used because qurbs surface has same geometrical property as bezier surface on the boundary

本文根据船体型值表的数据，用nurbs曲面来描述完整船体曲面，对插值曲面边界条件构造及节点矢量计算进行了研究，实现了船体曲线曲面的nurbs表达。 - Then the reconstruction of curved surface of the covering parts was taken for an example , and the emphasis is laid on the identification and extraction method of the characteristic and the boundary , and the reconstruction method of curved surface . meanwhile it was given emphasis to the partition strategy of the data of point cloud , the forward direction design of the process of re , and so on
在此基础上，以覆盖件曲面重构为例，重点研究了点云数据的分块策略、曲面特征的识别和提取方法、曲面边界提取和曲面重构方式，以及反求过程中的正向设计等。 - According to the comparison between simulation results and laboratory measurements , this paper reaches the conclusion that the negative pressure region in convex boundary ( including broken line gradient ) not only caused by boundary layer separation , but also especially caused by centrifugal force which is the result of convex boundary
根据数值计算与模型试验结果的比较，得出具有凸形曲面边界（包括折面底坡）负压区的存在不仅是边界层分离所致，边壁弯曲使过流产生的离心力也是产生负压的重要原因的结论。
