摘　　要：概述了主蒸汽管道和注蒸汽管道剩余寿命预测方法的发展状况,主要介绍了主蒸汽管道蠕变曲线逐步外推法和蠕变损伤及裂纹扩展寿命预测法。还对注蒸汽管道灰色预测方法、人工神经网络方法两种腐蚀剩余寿命预测方法进行了探讨。The residual life prediction methods of the steam injection pipeline and main steam pipeline are outlined. The gradual extrapolation method based on creep curves and prediction method of creep damage and crack growth life of the main steam pipeline, as well as, the gray theory forecast method and artificial neural network method of steam injection pipeline are introduced.
