中文摘要	In order to properly evaluate the service lifetime and security status of oil and gas pipelines, the defects should be quantitatively analyzed based on the features of the magnetic flux leakage (MFL) signals. An iterative quantitative analysis method based on radial-basis function (RBF) neutral network was put forward in this paper, and the detailed procedures of the iterative algorithm were introduced. And, by using self-adaptive mechanism to train the network, the convergence time was shortened and the local minimum in the error surface was effectively avoided. The results of simulation show this method has much faster training speed than standard backward propagation (BP) network, and the maximal error of quantification is only 0.26%. This method can be used to increase the quantification accuracy of MFL detection, and provide reliable basis for the security evaluation of oil and gas pipelines.
