free electron
基本解釋
- [物] 自由電子
英漢例句
- This represents the free electron.
這就是自由電子。 - It is a free electron so there is no potential energy to be accounted for.
對(duì)於自由電子,因此沒(méi)有什麼勢(shì)能。 - But we see if we have a free electron, as we do in this dotted line here, that's going to be a higher energy that's less stable.
但是我們看到如果,我們有一個(gè)自由電子,就像虛線(xiàn)所示那樣,那將會(huì)是一個(gè)較高的,不夠穩(wěn)定的能量。 - This should make sense, because if an atom has a very high electron affinity, that means it's really happy taking an electron from another atom, or taking a free electron -- that that's very favorable.
這應(yīng)該是郃理的,因爲(wèi)如果一個(gè)原子有很高的電子親和能,這意味著,它非常樂(lè)意從另外一個(gè)原子那裡奪取一個(gè)電子,或者得到一個(gè)自由電子--這是非常利於發(fā)生的。
