摘要
在给出涂层电阻率和管/地电位测试方法的基础上,利用实际测试数据,对涂层电阻率进行了推导计算。对采用断电法测试涂层面电阻率的方法提出了不同意见,建议使用阻抗为10MΩ的数字仪表对管/地电位进行测量。
On the basis of given measurement methods of coating resistivity and pipe/soil potential, the author inferably calculates the coating resistivity. For the method to measure the coating surface resistivity with the current-cut-off method,the author puts forward his own concept and suggests that the pipe/soil potential should be measured with 10 MΩ digital meter.
