摘要
现场测试结果表明,测量交流干扰电流密度时,不同测试方法(计算法和试片法)得到的测试结果存在差异引起差异的因素主要是:土壤电阻率测试值、试片的极化状态、阴极保护的影响和腐蚀位置区域特点等。
The field test results show that there is some difference in tests results of AC current density （JAC） between calculation and specimen method. The main factors causing the difference are test value of earth resistivity, polarized state of specimens, influence of cathodic protection and characteristics of corrosion area.
