极光的出现缘于太阳风离子与高层大气中的氧氮原子的碰撞。

Auroras happen when ions in the solar wind collide with atoms of oxygen and nitrogen in the upper atmosphere.

但最新的研究显示太阳风中氧氮同位素比例与地球、月球或是火星上的比例并不相同。

But the new study shows that the ratio of oxygen and nitrogen isotopes found in the solar wind is different from the ratio here on earth, or on the moon or Mars.

由于钢中氧氮对钢的性能和质量有明显影响，准确测定氧氮的含量对改进工艺控制、改善钢的性能、提高钢的质量具有重要意义。

It is important to accurately determinate the contents of oxygen and nitrogen in steel to improve process control, properties and quality of steel.

So between b e, and b, between n and o, magnesium and aluminum, and then phosphorous and sulfur, what we see here is that we're kind of going down, or quite specifically, we are going down.

比如从铍到硼，从氮到氧，从镁到铝，从磷到硫，我们在这些地方看到有点下降，或者可以明确地说，我们确实在下降。

So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.

那么，在这种情况下，我们看到氮的形式电荷是负的，而在这种情况下，氧的是负的。

So that explains one of our glitches here, but we have another glitch, and that second glitch comes between nitrogen and oxygen.

那么我们的第一种小偏差已经解释清楚了，但是我们还有另外一种，它在氮和氧之间发生。
