They can be expressed as ordered vectors , unordered groups , linked lists , trees , graphs or other forms that the programming language supports 它們可以表示為有序的向量、無序的組、鏈表、樹、圖或編程語言支持的其他形式。
The addition formula of spherical harmonics function of degree n and order 1 is derived using the relations between coordinate varieties after coordinate rotating and the property of the associated legendre polynomial . the relations among the magnetic vector potential , the modified magnetic vector potential and the second - order vector potential ( sovp ) are shown going forward one by one . it is explained that the solutions of electromagnetic fields in different coordinate systems can be transformed and an example having analytical solution is given 利用坐標(biāo)旋轉(zhuǎn)后球坐標(biāo)變量間的關(guān)系和連帶勒讓德多項式的性質(zhì)推導(dǎo)得到了n次1階球諧函數(shù)的加法公式;以遞進的方式說明磁矢量位、修正磁矢量位與二階矢量位的關(guān)系,寫出了引入二階矢量位的過程;以時諧場矢量邊值問題為例,闡明了不同坐標(biāo)系下電磁場解的相互轉(zhuǎn)化原理,給出了一個解析解的轉(zhuǎn)化例子;在球坐標(biāo)下,引入了較球矢量波函數(shù)更普遍的兩類矢量函數(shù),給出了其在球面上的正交關(guān)系。
