van allen radiation 中文意思是什麼
van allen radiation
解釋
范艾倫輻射-
Van allen radiation belt
范艾倫輻射帶 -
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，為了能使通信衛星在vanallen輻射帶正常工作，必須要有一種強抗輻射並且具有較高重量比功率的太陽電池。 -
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
譯為:在所有藉助火箭和衛星才能獲得的對外層大氣的發現中，在重要性方面很少能與范艾倫1958年發現高層輻射帶相比。 -
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，在這個軌道高度上存在所謂vanallen輻射帶，在這里即使是「抗輻射」的si太陽電池也只能正常工作幾天時間。 -
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
雖然地球上的磁場能將環繞地球的帶電荷粒子困於其輻射帶van allen belts ，一般能有效阻擋太陽風，但在猛烈太陽風情況下它可能受影響而變形，導致地磁暴的出現。 -
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
雖然地球上的磁場能將環繞地球的帶電荷粒子困於其輻射帶（ vanallenbelts ） ，一般能有效阻擋太陽風，但在猛烈太陽風情況下它可能受影響而變形，導致地磁暴的出現。 -
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
目前國內外用於航天器上的太陽電池主要為si和gaas太陽電池，但這兩種材料的抗輻射能力較差，其光電轉換效率由於高空輻射衰減很快，因而壽命短，穩定性差，不能滿足用於vanallen強輻射帶的空間應用需要。
