Van Allen belt

同根派生

In the lower Van Allen Belt, the proton intensity is about 20,000 particles with energy above 30 MeV per second per square centimeter.
在較低的範(fàn)愛(ài)倫帶，質(zhì)子密度是每秒每平方厘米大約20,000個(gè)能量在30兆電子伏以上的粒子。
The Van Allen belts are composed of charged particles trapped by the earth's magnetic field.
範(fàn)阿倫帶由地球磁場(chǎng)俘獲的帶電粒子所組成。
However,on February 21,1963,Telstar I suffered damage caused by the newly discovered Van Allen belts.
然而;1963年2月21日通訊衛(wèi)星1號(hào)被新發(fā)現(xiàn)的範(fàn)艾倫輻射帶損害.
For this reason, extreme radiation hardness and high power/weight ratio solar cells, which can work properly in van Allen belts, must be developed.
因此,爲(wèi)了能使通信衛(wèi)星在van Allen輻射帶正常工作,必須要有一種強(qiáng)抗輻射竝且具有較高重量比功率的太陽(yáng)電池。
Of all the discoveries of the outer atmosphere made possible by rockets and satellites, few equal in importance the revelation of the high radiation belt by Van Allen in 1958.
在使用火箭和衛(wèi)星對(duì)外層大氣取得全部發(fā)現(xiàn)中幾乎沒(méi)有什麼發(fā)現(xiàn)在重要性方麪能與Van Allen在1958年發(fā)現(xiàn)的高空輻射帶相提竝論。
