当磁场最强，太阳黑子最丰富的时候，它们会聚集在赤道附近。

When the magnetic field is at its strongest, and sunspots at their most plentiful, they cluster close to the equator.

天文学家最终确实发现了太阳黑子与磁场的关系。

Astronomers did eventually figure out what sunspots had to do with magnetic fields.

这是因为磁场降低了施加在内部气体上的压力，使得太阳黑子比太阳表面的其他部分温度更低。

That's because magnetic fields reduce the pressure exerted on the gases inside of them, making the spots cooler than the rest of the Sun's surface.
