The authors analysed 340,000 years of oxygen and hydrogen isotope data from three ice core sites across East Antarctica, alongside isotope-enabled general circulation model results.

科学家们分析了340，000年的横跨东南极洲的三个冰芯地址的氢氧同位素数据，并与同位素启用整体循环模式系统得出的结果。

In general, the heavier atoms in the atmosphere sink and the light ones remain at the surface, which is why some white dwarfs, for example, have mostly pure hydrogen or helium atmospheres.

总体来说，较重的原子在大气圈中沉积，而较轻的原子则存在于大气圈表面，这也是一些白矮星具有较纯净的氢和氦大气圈的原因。

And what you see when we see it with our eye, which is all the wavelengths, of course, mixed together, is whichever those wavelengths is most intense. So, when we looked at the individual neon lines, it was the orange colors that was most intense, which is why we were seeing kind of a general orange glow with the neon, which is different from what we see with the hydrogen.

当你们用眼睛看时，当然看到的是全波长，是混在一起来，看到的是最强的那些波长，当我们看单个氖谱线时，橙色是最强的,所以我们看氖光整体是橙色的,这和氢气是不一样的。
