The polarization measurement with exponentially decaying current is a transient electrochemical testing technique.
指数律衰减电流极化是一种暂态电化学测量技术，已发表的数据处理方法或者比较繁琐，或者引入了近似。
The appearance of critical point of the potential-time response of exponentially decaying current was ensured from theoretical analysis, and this has constituted the theoretical foundation of the critical point method for the measurement of corrosion current of metals.
本文为适应腐蚀体系中受力试样的腐蚀速度快速测定,对指数律衰减电流的电位响应进行了研究,从理论上导出指数律衰减电流极化的电位响应曲线上有极值点存在,这是用指数律衰减电流极化极值法测定金属腐蚀速度的理论基础。
