研究表明，在阴极保护实际工程应用中，传统的通电12s后断电3s的测量方法并不能得到准确的断电电位数据。IR降的正确测量可以通过专业仪器得到，也可在工程现场用万用表进行简单测量后进行修正得到。另外，在正常情况下，一100mV极化可以将电化学腐蚀速率降低到原来的2％；极端情况下也可以降低到原来的1／7。因此应该重视-100mV的极化标准，并将此准则同样视为阴极保护工程验收的一条重要标准。

The research has shown that, in project application of cathodic protection, the accurate electric potential data can not be got by conventional measures, i.e. measurement after power on for 12 s and power off for 3 s. The correct measurement of IR drop can be obtained by special instrument or by universal meter after correction. In normal conditions, - 100 mY polarization can reduce the electro - chemical corrosion rate to 2% of the original and 1/7 of the original in extreme case. Great attention shall be paid to - 100 mV polarization standard, which shall be regarded as an important standard in the inspection and acceptanee of cathodic protection project.
