| Abstract: | The evaluation criterion of external anticorrosive coating degradation for buried gas pipeline was introduced.Taking asphalt anticorrosive coating as an example,by using the theory of an Markov chain,the application of an inverse matrix in prediction for coating degradation was illustrated,which provides a basis for determining the aging distribution of the pipeline's external anticorrosive coating. |

| Keywords: | external anticorrosive coating Markov chain inverse matrix prediction |
