| 摘 要： | 根据低频涡流场的特点,本文导出了能直接应用于直角坐标系的矢量渐近边界条件,它有利于有限元模拟具有较大纵横比的导体在外场激励下的涡流问题。在算例中,本文将Ｅ表述（Ｅ－ｆｏｒｍｕ－ｌａｔｉｏｎ）的棱边有限元法计算的结果与其他方法得出的结果进行了比较。

| Abstract: | According to the characteristic of low frequency eddy current field,a vector asymptotic boundary condition(ABC),which can be used directly in the rectangular coordinates and is effective in simulating unbounded eddy current field with external field excitations is derived.In the given examples,the comparison between the results obtained by using E formulation eddy current finite element and those by using other approaches is carried out |
