A kind of rigid polymer microsphere with core shell structure was synthesized by multi step composite emulsion polymerization technique.
通过多步复合乳液聚合方法合成了一种具有核壳结构的刚性聚合物微球。
First through a low velocity core, and then through a high velocity shell, where their speed is increased before they are transmitted into the surrounding seawater.
它们首先通过一个低速的核心,然后通过一个高速的外壳,在它们被输送进周围的海水之前,它们的速度提高了。
Plate movements are the surface expressions of motions in the mantle—the thick shell of rock that lies between Earth's crust and its metallic core.
板块运动是地幔运动的表面现象。地幔是位于地壳和金属内核之间的一层厚厚的岩石壳。
So let's do a quick clicker question, and you tell me how many valence electrons does fluorine have? Remember, valence electrons are different from core, they're only the outer-most electrons in the outer-most shell.
那么让我们来做一个小选择题,请大家来告诉我,氟有多少个价电子,要记得,价电子与芯电子不同,它们是在最外壳层的最靠外面的电子。
So what I want to point out when you're kind of looking at these numbers here, what the significance is, look at that huge difference between what the ionization energies are for what we call those valence electrons, -- those outer shell electrons, those are core electrons there.
我在这里想要指出的是,当大家在看这些数字的时候,最重要的是,要看到这些,巨大的差异,看到所谓价电子,即外层电子的电离能与,1,s,轨道,电离能之间的巨大差异。
