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.
在较低的范爱伦带，质子密度是每秒每平方厘米大约20,000个能量在30兆电子伏以上的粒子。
The Van Allen belts are composed of charged particles trapped by the earth's magnetic field.
范阿伦带由地球磁场俘获的带电粒子所组成。
However,on February 21,1963,Telstar I suffered damage caused by the newly discovered Van Allen belts.
然而;1963年2月21日通讯卫星1号被新发现的范艾伦辐射带损害.
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,为了能使通信卫星在van Allen辐射带正常工作,必须要有一种强抗辐射并且具有较高重量比功率的太阳电池。
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.
在使用火箭和卫星对外层大气取得全部发现中几乎没有什么发现在重要性方面能与Van Allen在1958年发现的高空辐射带相提并论。
