摘　　要：构造了一个简单算例来显示在凸域中应用修匀技术也可能产生一个与最优网格相差很大的结果，进而说明在网格几何优化中应用数学规划法的必要性．A simple numerical example is proposed in this paper to show that the application of the smoothing technique can posssibly result in a sub stantial discrepancy markedly different from opti mal mesh in a convex region. This demonstrates the necessity of aPplying mathematical programming to the mesh optimization.
