预处理的铂电极对一系列金属离子Ｍ２＋活度阶梯变化的响应都是非单一突跃型瞬 时信号。提出了离子交换反应历程，认为离子水合吉氏自由能 相当于离子交换 反应的活化能。用离子交换过程面 与西 之差合理地解释了不同离子瞬时信 号峰高的次序、证明电极瞬时电位不是决定于离子扩散速度而是决定于离子交换速度。
The response of the pretreated platinum electrode to a series of metal ion M2 + activity steps is a non-single transient type transient signal. The ion exchange reaction process is proposed, and the Gibbs free energy of ion hydration is equivalent to the activation energy of ion exchange reaction. Using the difference between the ion exchange process and the west, the order of the peaks of different ion transient signals is reasonably explained. It is proved that the electrode transient potential is not determined by the ion diffusion rate but by the ion exchange rate.
