本文使用Ansys有限元分析软件，建立三维跑道线圈模型，考虑超导线截面电流密度的非均匀分布特性，计算Bi系高温超导双饼线圈中各区域磁场分布、临界电流分布、电流密度分布和电场分布，从而计算线圈的I～E关系曲线，为超导线圈提供一个更为准确的检验标准，对照线圈的测试结果，用此程序计算的线圈I～E关系曲线与测试曲线吻合的较好．
Considering the inhomogeneous current density distribution inside the Bi-2223 tape, we create a three dimension model of HTS double pancake coil and write an APDL program using Ansys software for calculating distributions of the magnetic field, critical current, current density and electric field in HTS solenoids made of pancakes. By using the program, one can choose his own criteria of the HTS double pancake coil＇s critical current. The double pancake coil was also fabricated and tested, there was little different between the tested and calculated result on the coil＇s I～E character.
