The intensity is determined by a felicitous arrangement of the atomic energy levels.

这一强度取决于原子能级的适当排列。

As a result, the complex atomic energy levels can be evaluated according to these expressions more easily.

因此按照这些表达式，可以相当容易地计算出复杂原子的能级。

However, lattices come with a price. Their oscillating electromagnetic fields typically and severely distort atomic energy levels.

可是网格造价昂贵，而所需的振荡电磁场严重的扭曲了原子能级。

Now I have lambdas associated with transitions between energy levels in atomic hydrogen.

现在我把波长和,氢原子中的,能级跃迁联系起来。
