摘　　要：针对WDP-500C型平面光栅单色仪未设有千位数字,致使其报警时不能正确处理的问题,提出了根据滑块的传动距离加长挡光板或将光电报警开关向短波段移动8.0 nm的解决方案,消除了由于单色仪设计问题而产生的故障.There is no kilo-digit in WDP-500C plane grating monochrometer, so it can not alarm correctly. In this paper, two methods are presented to improve it according to the gear distance. One is to lengthen the light obstruction; the other is to move the photoelectric alarming switch to shortwave length side by 8.0 nm. These two methods successfully eliminate the design fault of the monochrometer.
