Unlike other radio broadcasts , short-wave transmissions , bouncing off the ionosphere , can connect any two points on earth .

和其他的无线广播不一样，短波传送能从电离层反射回来，连接地球上任何两点。

The ionosphere is distinguished from other layers of earth 's atmosphere because it is electrically charged through exposure to solar radiation .

电离层与地球大气的其他圈层是不一样的，因为它是暴露在太阳的辐射之下，故而带电。

This energy soon showered earth 's upper atmosphere , tearing apart atoms in a region called the ionosphere to a greater depth than an ordinary solar flare and causing them to glow .

这个能量很快显示到地球的外大气层，将在电离层中的原子击开，使它们发出比普通太阳耀斑使它们发的更亮的光。

Though full details have yet to be released , the bbc understands that scientists also observed a " huge " signal in the ionosphere before the magnitude 7.8 earthquake in china on 12 may .

虽然详细的资料尚未公布，按照bbc的理解科学家们也曾观测到中国五月十二日发生7.8级地震前出现在电离层的“巨大”信号。

This extra energy would be funnelled down towards the magnetic poles , so molecules in the ionosphere above these regions could be accelerated enough to escape ( see diagram ) .

这些额外的能量就朝着行星的磁极集中起来，所以在行星磁极上面的电离层里的空气分子可能会加速而逸出地球（见图）。
