摘　　要：通过正交实验和验证实验确定极谱测定苯胺中微量硝基苯的最佳条件,同时对悬汞电极、静态滴汞电极、滴汞电极等3种电极模式以及微分脉冲极谱和经典直流极谱2种极谱类型进行了实验比较,得出相应的结论。The optimum polarographic conditions are obtained by orthogonal test and verification test. Some comparisons a mong three electrodes （HMDE, SMDE, DME） by tests, also some comparisons between differential pulse polarography and classic direct current polarography are carried out, and some concludes are obtained, respectively.
