摘要: 研究了在电极表面的等效电路为极化电阻Rp与表面电容C并联的情况下由正弦波动电流扫描极化曲线所形成的滞后圈。推导并验证了极化曲线和滞后圈高度的方程式。发现,根据滞后圈高度可以同时测定Rp和C。由于滞后圈高度是在极化电流密度i=0时测定的,溶液电阻不影响测量结果,所以这种方法适用于高电阻率的介质系统。测定了Fe在一次蒸馏水中和长春自来水中的Rp和C。

Abstract：The hysteric ring formed on sine waveform galvanodynamic polarization curve was investigated under the condition that the surface impedance may be represented by a polarization resistance R_p connected parallelly with a boundary capacitance C. Equations for polarization curve and the height of hysteric ring were derived and examined. It was found that R_p and C may be determined simultaneously from the height of hysteric ring. Because the height of hysteric ring was measured at i=0, the measurements were unaffected by solution resistance and thus this method may be used for high resistance system R_p and C of Fe in distilled water and in the tap water in Changchun were determined by the method proposed.
