常見例句雙語例句So really, you can not ever rotate a double bond, it makes your molecule very rigid.實(shí)際上，你不能轉(zhuǎn)動(dòng)一個(gè)雙鍵，它使得你的分子很堅(jiān)固。So if we look at its length, it's actually shorter than a single bond, but longer than a double bond.因此如果我們看它的鍵長(zhǎng)的話，它實(shí)際上比單鍵更短，卻比雙鍵更長(zhǎng)。Electrons can cause this double bond to rotate, which places part of the wheel in close proximity to a bulky side-molecule attached to the hub.電子可以使這個(gè)雙拼接口鏇轉(zhuǎn)，使得輪子的一部分緊靠連接輪轂的一個(gè)大型從屬分子上。原聲例句So if we look at its length, it's actually shorter than a single bond, but longer than a double bond.因此如果我們看它的鍵長(zhǎng)的話，它實(shí)際上比單鍵更短，卻比雙鍵更長(zhǎng)。麻省理工公開課 - 化學(xué)原理課程節(jié)選And we find the same thing for these two atoms here, it's not actually a double bond, it's somewhere between a single bond and a double bond.而且我們發(fā)現(xiàn)這兩個(gè)原子的情況是一樣的，它其實(shí)不是一個(gè)雙鍵，而是介於單鍵與雙鍵之間的。麻省理工公開課 - 化學(xué)原理課程節(jié)選And something that we'll see later on is that triple bonds, for example, are going to be stronger than a corresponding double bond or a corresponding single bond.而我們以後還會(huì)看到三鍵，擧例來說，應(yīng)該更強(qiáng)，相較於相應(yīng)的雙鍵,或者相應(yīng)的單鍵來說。麻省理工公開課 - 化學(xué)原理課程節(jié)選權(quán)威例句The citral molecule has a double bond in its tail, which, when it comes into contact with acid, forms a circular structure.FORBES: Magazine ArticleAcitral, according to Turin, has no double bond and lasts longer.FORBES: Magazine ArticleNot exactly a subtle cover for Shlomo Bond, Double-Oy-Seven.FORBES: Did Anonymous Hack Israel's Mossad Spy Agency? 返回 double bond
