摘　　要：本文报道交流电频率对示波极谱中和滴定终点时示波图变化的影响,指出各种变化方式取决于io/f比。The effect of frequency of alternating current on oscillopolarogram at the end-point of oscillopolarogram neutralization titration was studied. When the frequency is low, the appearance or disappearance of incision is observed. At higher frequency, the change of oscillogram is mainly contraction or expansion, At still higher frequency, a simple position shift of oscillogram at end-point is investigated. The type of change of oscillopolarogram depends on the value of i_0/f.
