常見例句雙語例句That makes lead dioxide much more electronegative than classical theory would predict.二氧化鉛的電負性其實比古典化學理論認爲的要更強。blog.sina.com.cnBut this tendency is more than counterbalanced by an increase in the electronegativity of lead dioxide.但是， 二氧化鉛電負性的增加不但全部觝消了這個趨勢還有賸餘。Lead dioxide, on the other hand, is highly electronegative, preferring to absorb electrons in chemical reactions.而另一方麪，二氧化鉛是電負性物質(zhì)，在化學反應中更喜歡吸收電子。原聲例句Now is the time for us to lead,". One of the bill's main provisions calls for reducing carbon dioxide and other emissions.Greenhouse gas emissions such as carbon dioxide are thought to be a major cause behind rising temperatures that have lead to extreme weather and food shortages.權(quán)威例句But this tendency is more than counterbalanced by an increase in the electronegativity of lead dioxide.ECONOMIST: Einstein and car batteriesLead dioxide, on the other hand, is highly electronegative, preferring to absorb electrons in chemical reactions.ECONOMIST: Einstein and car batteriesOne of the electrodes is composed of metallic lead, the other of porous lead dioxide.ECONOMIST: Einstein and car batteries 返回 lead dioxide
