【摘要】 介绍了埋地燃气管道外防腐层老化状况评价标准,以沥青外防腐层为例,通过应用马尔可夫链理论,阐述了基于逆阵的外防腐层老化状况预测的方法,从而为确定整条管线外防腐层老化状况分布提供了理论依据。更多还原

【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.更多还原
