摘　　要：提出了一种在边界推进法基础上的改进算法，该法结合了映射法和非结构化网格划分方法的优点，避开了它们的缺点，实现了曲面网格的快速生成，且保证了网格的质量．?An improved advancing front method is formulated for the triangulation of curved surfaces. It takes the advantages of mapping and non - struetural mesh generation methods,and avoids simultaneously their shortcomings. With the help of the improved method,mesh of high qua1ity can be generated eppiciently.
