摘要
本文讨论溢流曲面的形状优化问题．介绍了如何进一步完善同步迭代法，以求解具有可变区域、流量未知的二维势流的变分问题，在此基础上探讨溢流曲面多目标形状优化和方法。初步应用是成功的，文末给出了示例。
he paper discusses the shape optimization of overflow surface of spillway. There are two main parts: One is a synchronotls iterative method to solve a variational problem with variable domain and unknown discharge for 2--D ideal potential flow; The other concerns an approach to multiobjective optimal design of overflow surface. The primary application is successful and desirable.
