摘　　要：该文针对电磁场有限元计算的特点 ,深入研究了涡流检测系统中电磁场有限元后验误差估计的误差模选择问题 ,并在分析Zienkiewicz -Zhu方法在电磁场有限元后验误差估计应用中存在局限性的基础上 ,提出了一种适合于涡流检测系统中电磁场有限元分析的后验误差估计新方法。在此基础上 ,结合JamesR .Stewart和ThomasJ .R .Hughes所提出的简单实用的有限元算法 。In this paper, aiming at the finite element calculation characteristic of electromagnetic field, the posteriori error estimation of electromagnetic finite element analysis of eddy inspection system is researched deeply. On the basis of pointing out the limitation of Zienkiewicz-Zhu method applied to the posteriori error estimation of electromagnetic finite element, a new method of posteriori error estimation of electromagnetic finite element of eddy inspection system is presented. Based on this method, combining with the simple and practical finite element calculation method presented by James R. Stewart and Thomas J. R. Hughes, a new hp adaptive finite element strategy used for the electromagnetic finite element analysis of eddy inspection system is presented.
