galactic cosmic rays

基本解释

The space particle environment is composed of galactic cosmic rays, solar flares and geomagnetically-trapped particles.
空間高能粒子環境由銀河宇宙射線、太陽宇宙射線及地磁捕獲粒子組成。
Understanding more about the heliosphere and its ability to filter out galactic cosmic rays could be critical for assessing the safety of human space travel, Schwadron notes.
對日球層和它過濾宇宙射線的機制了解的越多，就越有助於評估人類星際航行安全性。
The intensity of Galactic cosmic rays is nearly isotropic because of the influence of magnetic fields in the Milky Way.
由於銀河系磁場調制的影響，我們觀測到的宇宙線是非常接近各曏同性的。

As plans for deep space exploration ramp up, radiation is a big concern — from high-energy galactic cosmic rays spewed by distant supernova explosions to sporadic bursts of charged particles hurled by the sun.
