galactic cosmic rays

基本解释

The space particle environment is composed of galactic cosmic rays, solar flares and geomagnetically-trapped particles.
空间高能粒子环境由银河宇宙射线、太阳宇宙射线及地磁捕获粒子组成。
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.
对日球层和它过滤宇宙射线的机制了解的越多，就越有助于评估人类星际航行安全性。
The intensity of Galactic cosmic rays is nearly isotropic because of the influence of magnetic fields in the Milky Way.
由于银河系磁场调制的影响，我们观测到的宇宙线是非常接近各向同性的。

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.
