用优化法根据模拟的电子束轨迹设计了用于制造条状彩色荧光屏的校正透镜．通过计算机模拟曝光，证明了所设计的校正透镜使着屏偏差得到了充分的校正． The optimization method is used to design the correction lens used to fabricate the strip color phosphor screen based on the simulated electron beam trajectory. By computer simulation of exposure, it proves that the designed correction lens has fully corrected the screen deviation.
