摘要
通过对GP -1型光电效应实验仪经常出现问题的分析 ,提出了数字光电效应实验仪的设计原理和具体电路 ,并且利用数字光电效应实验仪测量了相应的实验数据 ,结果表明该设计方案简洁可行。
Byanalyzingthe problems,whichoften appearin the apparatus ofGP-Iphotoemission,the design principle and elecˉtro circuits are put forward and experiment data are measured by using this apparatus.The results showthat the design schedule is concise and available.
