They lack the ability to delocalize the electron deficiency on oxygen. 它们没有使氧原子上的部分正电荷离域的能力。
And by here, I mean it's net neutral, but the electron deficiency. 我的意思它是电中性的,只是有些缺电子。
But can you see that the centers of electron deficiency lie on a sphere equidistant from the center? 但你看得到么,缺电子的地方分布在,与中心等距的一个球面上?
ATPase location in plasma membrane of phloem cells in lateral veins and major veins was based on Pb precipitate observed with electron microscope. Mg deficiency seemed to inhibit ATPase activity in phloem cells. 叶脉韧皮部细胞膜上ATPase活性在缺镁时较低,电镜下观察到细胞膜上黑色的铅沉淀少;
But the fact that the excess bariums are responsible for electron emission may be reconciled with the deficiency of alkaline earth metals during life by the dynamical surface emission center model. 然而超额钡仍然是发射电子的泉源,可以通过动态表面发射中心模型而与寿命中碱土金属下降统一起来。
