一、引言双水内冷发电机空芯铜导线缓蚀剂的研究是一项很有实际意义的研究课题。双水内冷发电机空芯铜导线的冷却水是低电导介质(<10μs/cm),通常的电化学方法如塔菲尔直线外推法、线性极化法等极化测量方法已不适合于低电导介质体系的研究,而交 I. INTRODUCTION The research on corrosion inhibitor of hollow copper conductor of double water internal cooling generator is a very significant research topic. The cooling water of hollow copper conductor of double water internal cooling generator is low conductivity medium (<10μs / cm). The usual electrochemical methods such as Tafel linear extrapolation and linear polarization are not suitable In low conductivity medium system research, and pay
