  1. 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。
  2. One of these patches has normally directed flux ( in the same direction as the overall dipole field in that hemisphere ) ; the other has the opposite, or reversed, flux

    斑塊之一具有正常方向的磁通量（與該半球整體的偶極方向相同） ；另一個斑塊的通量方向則是相反的。
