magnetosphere

The energy of the particles and the fields in the magnetosphere can vary by large amounts.

带电粒子的能量大小与磁气圈中的磁场的大小变化极大。

The movie almost gets this one right—Earth’s magnetosphere does protect us from blasts of subatomic particles from the sun.

影片在这点上倒是说对了，地球的磁气圈确实保护我们免受太阳风中亚原子颗粒的直击。

The rate at which the solar wind transfers energy to the magnetosphere can vary widely, but what determines the rate of energy transfer is unclear.

太阳风将能量转化至磁气圈的速率变化很大。 但是目前为止，我们仍不清楚到底是什么在决定着这种传送速率。
