| 摘 要： | 从电化学理论出发，建立了当系统略偏离平衡状态时，矿物－溶液界面的面极化等效电路模型．利用非线性网络理论，分析计算了一般电流激发下等效电路的过电位响应．通过对黄铁矿和石墨两类标本的实验对比，证明该等效电路模型是合理的，所作的分析计算是正确的，为进一步研究激发极化的非线性效应提供了合适的理论模型．

| Abstract: | A new nonlinear equivalent circuit is proposed to describe the mineral-electrolyte interface when the induced current density is not very large.The Volterra/Winner nonlinear system theory is applied to analyse the circuit.A formula is obtained to calculate overvoltage of the circuit,and cathode/anode polarization curves of pyrite and graphite are calculated theoreticaly using the formula.Comparsion of these curves with experiment results shows that the proposed circuit is suitable to describe the nonlinear system,it can be used to study the nonlinear effect of spectral IP. |
