For example, just before war broke out, several young women smuggled a portable transmitter disguised as an ordinary car radio into Germany. 例如,在战争爆发前不久,几个年轻妇女把一台手提发射机伪装成普通的汽车收音机偷运进德国。
Mobile Ad hoc Network ( MANET) is a multihop provisional autonomy system that is made up of a group of portable terminals with wireless transmitter, in which mobile nodes communicate with each other without the required intervention of any centralized access point or fixed infrastructure. 移动adhoc网络(移动自组网或MANET)是指由一组带有无线收发装置的移动节点组成的一个多跳的、不需要固定中心接入点或者基站支持的自治系统。
In this paper, the authors mainly deals with laws of MF electromagnetic waves transmitted by a horizontal magnetic dipole in a conductor-free coal seam which provides useful theory and data for further research of underground communications and development of underground portable transmitter and receiver. 本文主要研究由水平磁偶极子天线发射的中频电磁波,在井下无导体煤层中的传播规律。它可为进一步研究井下无线电通信和研制井下便携式无线电收发机,提供可参考的理论和数据。
External wireless-communication controller was designed for interaction, and portable wireless energy transmitter was realized. 体外无线控制器实现交互式遥控器设计,无线能量发射装置完成便携式改装。
