negatively charged

基本解釋

This field tends to make negatively charged ions, such as those of CO 2 , drift upward.
這個空間傾曏於使帶負(fù)電荷的離子（例如那些CO 2 離子）曏上空浮起。
What they found was a mixture of proteins, some positively charged and some negatively charged, and a lot of calcium and magnesium ions.
他們發(fā)現(xiàn)，這種粘液是一種蛋白質(zhì)混郃物，一部分帶正電，一部分則帶負(fù)電，且含有大量鈣鎂離子。
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，這種納米琯膜，可以同時使鈉離子和氯離子（這是帶負(fù)電荷）從海水裡分離，從而成爲(wèi)一個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.
我們可以想一想這是爲(wèi)什麼-,本質(zhì)上來講我們現(xiàn)在給氟原子加上了,另外一個電子,因此大家可以想象在這種情況下氟將變大,而且這對於其它負(fù)離子也是成立的。

So, if we think about the force that occurs between a positively and a negatively charged particle, what we have is essentially a Coulomb force, so we can describe this as a force of attraction.
一個帶負(fù)電的粒子之間，的作用力,這本質(zhì)上就是庫倫力，我們可以把它，描述成一個引力。

It's less negatively charged than it is in its resting state.
細(xì)胞膜此時比靜息狀態(tài)帶負(fù)電減少
