P transposable element P转座因子
P-element knockout P转座子基因敲除
p-block element p区元素
p block element p区元素
p-regular element p正则元
p nonconforming element p1非协调元
p version finite element p型有限元
p-version finite element method p型有限元
p-cAMP responsive element binding protein-1 磷酸化环腺苷酸应答元件结合蛋白
So we want to look at any element that has a 3 p orbital filled, but that does not then go on and have a 4 s, because if it had the 4 s filled then we would actually see six lines in the spectrum.
所以,我们要找一找有哪些元素的,3,p,轨道被占据,但没有,4,s,轨道被占据,因为如果,4,s,轨道也被占据了,那我们会在光谱中看到第六条谱线。
