negatively charged

常见例句

This field tends to make negatively charged ions, such as those of CO 2 , drift upward.
这个空间倾向于使带负电荷的离子（例如那些CO 2 离子）向上空浮起。

So a nanotube membrane that allows both sodium and chloride ions (which are negatively charged) to flow out of seawater could become a cheaper way to desalinate water.
因此，这种纳米管膜，可以同时使钠离子和氯离子（这是带负电荷）从海水里分离，从而成为一个淡化海水的便宜方式。

- And we can think about why -- essentially we have fluorine and now we're adding another electron. So you can picture that fluorine is going to get larger in this case And that would be true for all of the negatively charged ions.
我们可以想一想这是为什么-,本质上来讲我们现在给氟原子加上了,另外一个电子,因此大家可以想象在这种情况下氟将变大,而且这对于其它负离子也是成立的。
