v.使无色；使消色
The influence of input beam size on the maximum intensity in the focus of singlet lens and achromat was compared. 比较了消色差透镜及单透镜中脉冲初始光腰尺寸对聚焦的影响.
The results of antidazzling test showed that the part of discolor was able to finish the process of staining,achromatizing and photochromisming automatically,rapidly and reliable. 防眩实验结果表明:变色部分能够自动完成着色、消色和光致变色过程,工作稳定可靠;控制部分动作准确、运行良好。
