This has created a tremendous donut-shaped radiation belt around Jupiter, like Earth's Van Allen belts, but far more powerful.

这就在木星周围形成了一个巨大的环状辐射带，就像地球的范艾伦辐射带一样，但远比范艾伦辐射带强大得多。

When the magnetic field is working, these rays are safely herded away from the Earth's surface and into two zones in near space called the Van Allen belts.

如果磁场工作正常，这些射线会被安全地挡在地球表面之外，被赶进近空两个名叫“范艾伦辐射带”的地区。

As part of that magnetic shield that insulates Earth from the solar wind, the Van Allen belts sweep energized particles up and away from us.

作为将地球与太阳风隔离开来的磁屏蔽的一部分，范艾伦带将带电粒子向上扫起并远离我们。
