建立了边界元的全解析敏度分析技术，并将该技术与通用的形状优化设计相结合，在求解最优化问题时，把预测有效约束的方法用于该算法中，用这种新算法对二维的平面应力下的弹性体进行形状优化在优化例题时，用加权求和法处理该例题的多目标问题，最后获得满意的结果 The full analytic sensitivity analysis technique of boundary element is established. Combining this technique with the general shape optimization design, the method of predicting the effective constraint is used to solve the optimization problem. With this new algorithm, Shape optimization of two-dimensional elastic body under plane stress  In the optimization of the example, the weighted summation method to deal with the multi-objective problem of the example, and finally obtain satisfactory results 
