研究了一种快速监测防腐层状况变化的方法，并论述了相应的数学模型及评价方法。在实际应用中，可直接利用阴极保护系统的参数，也可自行布点测试获取数据来评价防腐层状况。在四川某管道上的应用表明该方法快速有效，可实现对防腐层状况的连续跟踪和动态监测，能快速发现防腐层缺陷的位置，降低管道维护成本。
Current coating detection technology and evaluation index are summarized. A method of fast monitoring coating is studied according to the existing coating detection technology, and the relevant mathematical model and evaluation method is discussed. In practice, one can evaluate coating using data of cathode protection system directly or using data from test by himself. The application to one pipeline in Sichuan indicated that the method is fast and valid, which can make the sequential tracking and dynamic monitoring of coating status come true, and the method can locate the coating defects quickly and decrease the maintenance cost of pipeline.
