在这张电镜照片的下半部的毛细血管袢中有2个高电子密度的RBC。
In this electron micrograph, the capillary loop in the lower half contains two electron dense RBC's.
发现在高电子密度下电子会向量子限制较弱的退局域态转移。同时还经由热电子隧穿而跃迁到表面态。
It is found that the electrons may be transferred into delocalized states with high energy and transited to surface states through hot electron tunneling under high electron concentration.
结果:脑缺血再灌注后大鼠脑细胞内出现大量高电子密度中毒颗粒及空泡,线粒体膜崩解、内嵴消失;
RESULTS: Many electron dense toxic granulation and vacuolus in mitochondria were observed in the rat brain of focal cerebral ischemia and reperfusion.
This should make sense because if something has a low ionization energy, that means it's not very electronegative, which means it's going to be a lot happier giving up electron density, which is essentially what you're doing -- when you're forming covalent bonds is you're sharing some of your electron density.
这应该是合理的,因为如果某物的电离能很低,这也就意味着它的电负性也不高,那么它就会更愿意,放弃一定的电子密度,而本质上这正是你在,形成共价键时所需要做的,分享你的一些电子密度。
