供氮水平 - 引用次数：4
The results showed that the fresh and dry weights of shoot and root,leaf area and root/shoot ratio were significantly increased as N level increasing from 2 to 4 mmol/L , and then decreased as N level further increased.
结果表明，供氮水平由2mmol／L增加到4mmol／L，生菜的地上干鲜重、根干鲜重、叶面积和根冠比显著增加，再增加氮浓度则显著下降。

We'll get to discussing that, but what I want to point out here again is the fact that instead of just being dependent on n, the energy level is dependent on both n and l.
我们将要讨论它，但是我想指出的是事实上能级不只是与n有关,而是与n和l都有关系，而且n不再是。

They're not going to want to add on another electron, because then it'll have to jump a very large energy level go from n equals 2, to n equals 3, and n equals 4, and so on.
它们不愿意增加另外一个电子，因为这会让它们跳到一个非常高的能级上去,依次是，n，等于，2，3，4，等等。
