中波通信
  • medium : n （pl dia ）1 媒介物；傳導體；媒質，基質，介質，介體；中間物；環境、生活情形。2 手段，方法；媒介...
  • wave : n 〈美海軍〉女志願軍人〈見 WAVES 條〉。n 1 波浪；碎浪； 〈the wave（s）〉 〈詩〉海。2 波動；波狀...
  • communication : n. 1. 通訊，通知；交換；信息；書信，口信，通報。2. 傳達，傳授；傳播；傳染。3. 交通，交通機關；聯系，連絡（設備）。4. 【宗教】接受聖餐。
  1. Short wave is used for wireless communication which the wavelength is from 10m - 100m. in fact, the high frequency part of medium wave usually belongs to short - wave band. so many short wave communication equipments ’ band was extended to 1. 5 - 20mhz

    實際上，許多人也把中波的高頻段（ 1 . 5 - 3mhz ）歸到短波波段去，所以現有的許多短波通信設備，其波段往往擴展到1 . 5 - 20mhz 。
  2. Standards for protective space between medium and short wave radio emission stations and cablecarrier communication systems

    中短波廣播發射臺與電纜載波通信系統的防護間距標準
  3. With these three calculated parameters, the attenuation factor value of the radio wave propagation in the earth ' s crust is calculated by the ways of plane wave method and communication formula method, and the value of the leakage on the ground is also calculated by the inhomogeneous medium ' s field analysis method

    據此三種參數，利用平面波法和通信公式法計算出電波在地殼中傳播的衰減因子值，以及利用非均勻介質的場分析法計算出地面場強泄露衰減因子值。
