为了得到一些信息，史密斯先生打开了电池供电的收音机。
In order to get some information, Mr. Smith turned on the battery powered radio.
这些收音机采用手摇式，由太阳能而不是电池供电。
The radios are powered by solar energy and hand cranks instead of batteries, a potentially helpful asset in a nation short on basic supplies.
麻省理工学院的马克·艾伦在介绍该成果时说：“如果把这种电池织入衣物，它们就能为一系列高科技设备，如手提收音机、GPS装置以及个人数字设备提供电源。”
The batteries, once woven into clothing, could provide power for a range of high-tech devices, including handheld radios, GPS devices and personal digital assistants.
