| 摘 要： | JONES电导池系统的交流阻抗由电极过程的相关阻抗和电极间溶液的电阻两部分组成，可用适当的等效电路模拟。采用LCR电桥测量JONES电导池中溶液的电阻时需要选择合适的等效电路为模型解析测量的交流阻抗。通过等效电路的分析发现，选择串联电路作为LCR电桥的解析等效电路测量JONES型电导池中溶液的电阻时引入的误差比并联电路小。

| Abstract: | The AC impedance of JONES type cell compose impedance corresponding to the electrodes surface process and the solution resistant between the two electrodes can be simulated by a suitable equal circuit. Parallel circuit or serial circuit must be determined for LCR to calculate the parameters of the measured impedance of JONES type cell. According to the equal circuit modeling JONES type cell, serial circuit servicing as a model to calculate the resistant of solution in JONES type cell, compared with parallel circuit, result in less error. |
