溶液电导率的绝对测量方法

ABSOLUTE MEASUREMENT METHODS FOR ELECTROLYTIC CONDUCTIVITY OF SOLUTION

概括论述了三种溶液电导率绝对测量方法 :基于精确测量电导池几何参数的测量方法、基于电容测量的溶液电导率测量方法和基于VanDerPauw方法的溶液电导率测量方法。前一种方法用于许多国家的溶液电导率基准测量 ,后两种方法可发展为溶液电导率测量的基准方法。

Three absolute measurement methods of electrolytic conductivity of solution were described, which were based on methods of the measurement of dimension of the conductivity cell, the measurement of capacitance of conductivity cell and Van Der Pauw theorem. The former method has been used widely as the primary standard of many countries and the later two are the potential primary standard methods.
