摘　　要：用有限元方法详细分析并计算了HT 7超导托卡马克等离子体实验装置上低杂波天线壁上的涡流分布、感应磁场位形和天线所受电磁力 .针对难以求解的磁场耦合问题 ,采用了新的迭代算法 .具体的分析方法和计算结果对于研究复杂电磁环境下金属板上的涡流及其所受电磁力的分布具有一定的借鉴价值 .It analyzes the eddy current,the distribution of the induced magnetic field and the electromagnetic force on the lower hybrid wave launching antenna on the superconducting tokamak HT 7 by using finite element circuit method.A new iterative algorithm is developed to analyze the coupled magnetic field.The method and results obtained are helpful to study the eddy current and electro magnetic force on metal plate placed in rather complicated electro magnetic environment.
