常見例句雙語例句In all groups of chemically similar elements the heaviest are the most electropositive.在化學性質相似的同族元素中，質量越重帶的正電越強。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性強，所以無法産生可用的電位差。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.産生的結果是，金屬鉛的電正性沒有古典化學理論認爲的那麼強（或者說，更爲電負性）——看起來似乎鉛不適郃用來做電池。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)化學導論課程節(jié)選Electropositive is down to the left because that is where the metals live.帶正電性的元素常,在左邊因爲那裡是金屬區(qū)。麻省理工公開課 - 固態(tài)化學導論課程節(jié)選權威例句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
