摘　　要：采用比较算法快速寻找数据库中与目标导流系数相匹配的电子枪尺寸,采用缩尺法改变其尺寸到所要求的目标尺寸。考虑电子枪尺寸对注腰半径、导流系数、层流性等参数的影响,建立了评价电子注性能的目标函数,采用单纯形法优化目标函数实现最优的电子层流性,且基于比较算法和单纯形算法的设计方法具有通用性,工作效率高。The dimensions of the electron gun are obtained by means of comparing algorithm to match objective perveance with the data in the database. Objective dimensions is acquired by the reduced scale method. An objective function is introduced, which takes account of perveance, beam waist and laminarity. A simplex method is applied to optimize the objective function to gain better electron laminar flow. The design of electron gun based on comparing algorithm and simplex method is efficient and has general application in electron guns with various properties.
