音标发音

The first critical step is to understand how the energy gets transferred from the solar wind to the magnetosphere.
首要的问题是，我们得搞清楚能量是如何从太阳风转化到磁气圈中去的。
Unlike the symmetrical pattern of the iron filings and magnet, the magnetosphere is pushed in on the side facing the Sun and stretched out in the Earth's wake.
与铁屑和磁棒对称整齐的磁场模式不同，地球磁层面向太阳的一面被向内推，在相反的方向上延伸出磁场的轨迹。
When the charged electrical particles approach the Earth, they carve out a highly magnetized region —the magnetosphere —which surrounds and protects the Earth.
当这些带电粒子接近地球时，便形成一个很强的磁场区--磁气圈--包围着地球并对地球起一定的保护作用。

Normally, the Earth's magnetosphere acts as a shield from these harmful particles and protects the environment.

Sometimes these plasma clouds are directed at Earth, and can deposit a large amount of energy into the planet's magnetosphere.

For the plasma to leak into the magnetosphere is quite an accomplishment.
ECONOMIST: Hot stuff

the region surrounding a planet, such as the earth, in which the behaviour of charged particles is controlled by the planet's magnetic field
