摘　　要：采用交流阻抗法测定了部分电解质溶液的复阻抗特性，结果表明，常规交流电桥法所采用的1-4kHz测试频率，较好地测定电解质溶液的真实电阻，并能有效地避免高频下电感的可能影响。The electric impedance of electrolyte solutions have been measured by using alternating Current impedance method. The results showed that the testing frequency at 1-4kHz adopted in regular alternating current bridge method could be used to measure the resistance of electrolyte solutions, and the possible influence of electrical inductance in higher frequency could be avoided effectively.
