摘要
提出一种用圆柱电极测定人造板电阻率的新方法。该方法利用圆柱电极测出人造板的电阻值，并按电轴法和静电比拟法求出其电阻率。与平板电极测定方法相比，操作简便，对试件破坏小，不易受接触电阻影响。采用两种方法对同一材料进行测试的结果表明，测定值间误差在１％以内。
This paper introduces a new measuring method of electric-resistivity for artificial board. Resistance value is measured with cylindrical electrodes and electric-resistivity is calculated with theory of electric-magnetic field. Comparing with other measuring methods, it has the advantages of easy measuring, little damaging to the tested samples and is not easily affected by the contact situation. The same sample was tested with two different kinds of methods and the deviation between measured results was blow 1% .
