摘　　要：针对电磁场数值分析中较常用的Whitney型和Mur型两类棱边有限元矢量插值函数 ,通过研究目前文献中这两类矢量插值函数的各种形式和它们的性质以及与节点元插值函数的关系 ,指出了虽然Whitney型和Mur型棱单元矢量插值函数形式各异 ,但其导出机理是一致的 。By considering the situation that the use of both Whintey type and Mur type of edge element is widespread,various forms of edge shape function of these types are summarized.The relation ship between edge and nodal shape function is studied in this paper.It is proposed that although various forms of edge shape functions for Whintey type and Mur type of edge element are different for each other,the deriving principles of them are identical.The unified deriving methods of them are given.
