  1. Firstly, in spherical coordinate system, the sovp formulation for the time - harmonic electromagnetic fields of the current dipole in conductive infinite - space is derived, using reciprocity theorem and transforming relations between special functions. then, selecting appropriate coordinate system, using superposition principle, the boundary - value problem of modified magnetic vector potential on the problem of a time - harmonic current dipole in spherical conductor is solved and analytical solution is obtained. finally, by means of the addition formulas of legendre polynomial and spherical harmonics function of degree n and order 1, the analytical solution in spherical coordinate system specially located is transformed into that in spherical coordinate system arbitrarily located

    首先利用特殊函數間的轉化關系和互易定理推導得到了無限大導體空間中球坐標下時諧電流元電磁場的二階矢量位形式：然後利用疊加原理，選擇合適坐標系，求解了導體球中時諧電流元的修正磁矢量位邊值問題，得到了問題的解析解；最後依據不同坐標系下電磁場解的轉化原理，藉助勒讓德多項式和n次1階球諧函數的加法公式，將坐標系特殊安放時的電磁場解析解變換到坐標系一般安放時的解析解，給出了球內電場和球外磁場的並矢格林函數。
  2. For a x - directed line current with lengh much smaller than a wave length, the e - field pattern on coordinate planes in 3 - d space in the region from much smaller than line length to one or two wave length, the synthesized pattern by summation of the field of many line segments of hertz dipoles is independent of the number of segments, i. e. same field as a single hertz dipole

    以水平面上三角形甚小於波長線電流為例，分割為若干小段之赫芝偶極所加總合成在三度空間任意座標平面上距離從甚大於線長到一兩個波長區域之電場場型與分割小段數量無關，即等同於一單一赫芝偶極之場型。
