electropositive

基本解釋

In all groups of chemically similar elements the heaviest are the most electropositive.
在化學(xué)性質(zhì)相似的同族元素中，質(zhì)量越重帶的正電越強(qiáng)。
Metallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.
比起鉛來(lái)，金屬錫的電正性沒(méi)有二氧化錫的電負(fù)性強(qiáng)，所以無(wú)法產(chǎn)生可用的電位差。

That has the effect of making metallic lead less electropositive (ie, more electronegative) than classical theory indicates it should be—which would tend to make the battery worse.
產(chǎn)生的結(jié)果是，金屬鉛的電正性沒(méi)有古典化學(xué)理論認(rèn)為的那么強(qiáng)（或者說(shuō)，更為電負(fù)性）——看起來(lái)似乎鉛不適合用來(lái)做電池。

So, at any moment, you know in any bond which is the more electropositive.
在任何時(shí)候，你都能判斷誰(shuí)是正電性的。
