摘　　要：本文分析了四种基于局部量计算的恒定磁场后验误差估计方法。通过对具有解析解的实例计算,研究了各种方法的精度,同时比较了各种方法计算所需的计算机时间、内存和优缺点,从而为自适应有限元过程提供了参考和依据。In this paper, four methods for local error estimation in finite element solution are described and analyzed. Using the analytic solution as a refer- ence, the accuracy, CPU time and computer storage of various methods for a model problem are compared and discussed. Some conclusions which can be acted as the theoretical basis for engineering use are obtained.
