用丝绸摩擦过的玻璃棒所带的电荷叫做正电荷,质子是正电荷,而正电荷不一定是质子,对应的电子即是负电荷,或多或少表现出的带正电或带负电,世间万物大多为电中性 物体由原子而来,原子又由电子和原子核(中子和质子组成)而来。

DABCO can extract dianion from the aqueous containing monoanion and dianion. The basic reason is that DABCO possesses two positive charges, which make up double identification center that shows special identifiable ability.
双季铵盐DABCO专一地将二价阴离子从含有一价、二价阴离子的水溶液中捕入有机相中,其根本原因是双季铵盐有两个正电荷,构成了对二价阴离子具有特殊识别能力的双识别中心。

然后上升气流将轻盈的、带正电荷的冰晶带到云的顶部。
Then updraft wind currents carry the light, positively charged ice crystals up to the top of the cloud.
在暴风云的形成过程中,带正电荷的粒子与带负电荷的粒子相互分离。
The separation of positively and negatively charged particles takes place during the development of the storm cloud.
我要说的是,完全相反,正电荷集中在中心,在一个非常非常小的体积内。
I'm going to say, quite to the contrary, the positive charge is concentrated at the center in a tiny, tiny, tiny volume.
I'm going to say, quite to the contrary, the positive charge is concentrated at the center in a tiny, tiny, tiny volume.
我要说的是,完全相反,正电荷集中在中心,在一个非常非常小的体积内。
If the atom is fixed mass, the electron is tiny, It must be the positives have all the mass.
如果是原子质量一定,电子很小,带正电荷的部分几乎占据了全部质量。
So we can do this for any final charge we have, if we have a molecule that has a charge of plus 2, then all of the formal charges should add up to plus 2 and so on.
对于任意净电荷的情况,我们都可以这样做,比如假设我们有一个带两个正电荷的分子,那么所有的形式电荷加起来应该等于正二,等等。
