常見例句雙語例句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，金屬錫的電正性沒有二氧化錫的電負(fù)性強(qiáng)，所以無法產(chǎn)生可用的電位差。ecocn.orgThat 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，金屬鉛的電正性沒有古典化學(xué)理論認(rèn)為的那么強(qiáng)（或者說，更為電負(fù)性）——看起來似乎鉛不適合用來做電池。原聲例句So, at any moment, you know in any bond which is the more electropositive.在任何時候，你都能判斷誰是正電性的。麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選Electropositive is down to the left because that is where the metals live.帶正電性的元素常,在左邊因為那里是金屬區(qū)。麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選權(quán)威例句In all groups of chemically similar elements the heaviest are the most electropositive.ECONOMIST: Einstein and car batteriesMetallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.ECONOMIST: Einstein and car batteriesThat 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.ECONOMIST: Einstein and car batteries 返回 electropositive
