van allen造句

• 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。
• Van allen radiation belt
  范艾伦辐射带
• Van allen belt
  范艾伦辐射带
• Van allen belts
  范艾伦带
• 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vanallen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 lmportance the revelation of the high radiation belts by van allen in 1958
  译为:在所有借助火箭和卫星才能获得的对外层大气的发现中,在重要性方面很少能与范艾伦1958年发现高层辐射带相比。
• However , there exist the so - called van allen radiation belts at this hight . the solar cells would work there for only several days , even for ‘ radiation hardness ’ si solar cells
  但是,在这个轨道高度上存在所谓vanallen辐射带,在这里即使是“抗辐射”的si太阳电池也只能正常工作几天时间。
• While the magnetic field on the earth which traps charged particles encircling the earth into radiation belts called the van allen belts normally protects our planet from the solar wind , it may be deformed in the event of violent solar wind , resulting in a geomagnetic storm on earth
  虽然地球上的磁场能将环绕地球的带电荷粒子困于其辐射带van allen belts ，一般能有效阻挡太阳风，但在猛烈太阳风情况下它可能受影响而变形，导致地磁暴的出现。
• While the magnetic field on the earth ( which traps charged particles encircling the earth into radiation belts called the van allen belts ) normally protects our planet from the solar wind , it may be deformed in the event of violent solar wind , resulting in a geomagnetic storm on earth
  虽然地球上的磁场能将环绕地球的带电荷粒子困于其辐射带（ vanallenbelts ） ，一般能有效阻挡太阳风，但在猛烈太阳风情况下它可能受影响而变形，导致地磁暴的出现。
• At present , the solar cells used on space aircrafts are still mainly si and gaas solar cells . however , the radiation resistance ability of these two materials is poor . since the photoelectric conversion efficiency attenuates rapidly with the radiation , the lifetime of si and gaas solar cells is short and their stability is not satisfied for space applications at van allen belt
  目前国内外用于航天器上的太阳电池主要为si和gaas太阳电池,但这两种材料的抗辐射能力较差,其光电转换效率由于高空辐射衰减很快,因而寿命短,稳定性差,不能满足用于vanallen强辐射带的空间应用需要。
