摘　　要：传统的三角划分不适合许多实际的应用 ,在复杂表面进行三角划分过程中 ,往往会出现局部狭长三角形。通过对传统优化方法的讨论 ,文中提出了局部网格狭长三角形优化的方法 。The traditional triangulation has been unsuitability in many applications. Long-narrow triangular mesh will often appeared among the course of triangulate the complex surface. Discuss with the traditional optimization a local Optimization Algorithm for Long-narrow Triangular Mesh is presented in the text. This algorithm can delete long-narrow shaped triangles effectively, and the triangular mesh will have its good shape.
