【Abstract】 Based on Van der Pauw equation, a new measurement method is developedfor the determination of the conductivity of ionic solution or melt, i.e., the me-thod using four squarel y-arranged electrodes .The calculation formula is derivedtherefore and a relevant conductometer type of DC- lis designed and made up. Acompetitive experiment shows the reliability of the new method with ease.更多还原
