摘　　要：以电子光学系统中发射系统为实例，从收敛速度、搜索效果、整体收敛性等几个方面，系统地对非线性规划的五种搜索方法在电子光学系统设计中的应用进行分析和比较，得出了一些有价值的结果。计算表明Rosenbrock法是电子光学系统最优化设计中最值得推荐的方法。Five different nonlinear programming techniques used in optimizing electron-optical system were discussed. Major aspets of these techniques in their applications were systematically studied, which include convergence rate,optimal objective function value and global convergence. Our calculation results indicated that Rosenbrock method should be recommended in electron-optical system optimization because of its many technical advantages over other methods.
