无线电通讯

The purpose of FedSMR is to provide spectrum-efficient trunked radio communications to a number of Federal users that can benefit from multiple talk groups and other features.

FedSMR的目的是为一批联邦用户提供波谱有效的无线电通讯以便能从多重通话小组和其他功能中获益。。

The soft X-ray flux of X class flares increases the ionisation of the upper atmosphere, which can interfere with short-wave radio communication, and can increase the drag on low orbiting satellites, leading to orbital decay.

在软X射线磁通的X级耀斑增加了离子化的高层大气，从而干扰短波无线电通讯，并可以增加拖累低轨道卫星，从而导致轨道衰减。

前项物料区及重要区之建筑强度应在普通住宅强度二倍以上，并应采用防火材料，装设自动火警侦测器、防盗警铃及消防系统，其进出口平常均保持锁住状态，且派管理人员看守外，於重要区周围并应装置夜间照明设备及配置无线电通讯设备。

To enable the reliable operation of the control system, the centers will be linked to more than 90 substations and power stations by over 1300 km of OPGW, ABB FOX 515 multiplexers, ABB ETL 600 Digital Power Line Carrier and radio communications.

为确保控制系统的可靠运行，这些中心将通过1300多千米的光纤复合地线、ABB FOX515多路器、ABB ETL 600 数字电力线载波机及无线电通讯，链接到90多个变电站和发电站。

Still,he could not help thinking that if anything should happen,the neatest could person he could contact by radio,unless there was a ship nearby would be on an island 885 miles away.
