摘　　要：本文推荐采用电流积分器和峰值保持(检测)器作为插入单元,以测量积分电量代替峰高测量,改进固体电极上的测量浓度范围。并采用峰值检测器提高记录仪的响应,使之适用于500～1000mV/s扫描速率下的伏安测定。本文以T(Ⅳ)作为例子证明上述优点。A current integrator and a peak height detector are proposed as an interposed unit sothat the readout of stripping coulometry being used instead of the peak current when the latter gives multiple waves, and a peak maximun being kept to ensure good precision of recorder. The determination of telluiium(IV)demonstrates the readout reliablity of recorder on voltammogram being significantly improved.
