chemical bond
常見例句
- The way the chemical bond arises from physics and certain accidents.
這些化學(xué)作用源于物理和特定的意外因素。 - What makes the new amino acids especially interesting is that they react with each other to form a different kind of chemical bond from those that usually hold proteins together.
更新奇的是，這兩個(gè)非天然氨基酸通過相互作用形成了一種特殊的化學(xué)鍵，這種化學(xué)鍵有別于通常情況下是蛋白質(zhì)亞基結(jié)合在一起的化學(xué)鍵。 - What's more, they've shown that these amino acids can react with each other to form a different kind of chemical bond to those which usually hold proteins together in their three-dimensional shape.
更重要的是，他們已經(jīng)表明，這些氨基酸可以相互反應(yīng)，形成與通常維持三維形狀的蛋白質(zhì)不同的化學(xué)鍵。 - So, in talking about covalent bonds, we should be able to still apply a more general definition of a chemical bond, which should tell us that the h 2 molecule is going to be lower in energy than if we looked at 2 separate hydrogen atom molecules.
那么，既然提到了共價(jià)鍵，我們應(yīng)該還可以,給化學(xué)鍵下一個(gè)更普遍的定義,那就是告訴我們氫分子能量應(yīng)該更低,與兩個(gè)分開的氫的單原子分子相比。

那么，下面我們將從成鍵開始講起，無論什么時(shí)候我們有一個(gè)化學(xué)鍵，基本上我們所討論的,都是如何安排兩個(gè)原子的原子核的位置,與電子的位置使得成鍵的兩個(gè)原子,最終比分開時(shí)的能量更低。
麻省理工公開課 - 化學(xué)原理課程節(jié)選 - So the point is, this balance between energy thatyou could think of as say bond energies in chemical reactions, and entropy that you can think of in terms of disorder, how many different possible combinations or configurations of something wrong, will dictate where the equilibrium lies.
關(guān)鍵在于，這種能量與熵之間的平衡,確定了平衡的條件，在化學(xué)中能量涉及鍵能，而熵和無序有關(guān),即有多少可能的不同組合或者形位，二者的平衡會(huì)告訴我們平衡態(tài)是什么樣子。

ECONOMIST: Schumpeter - One photon in a million comes away with a different frequency from the one that it arrived with because it changes the structure of a chemical bond in one of the plastic's molecules.
ECONOMIST: Recycling - For example, two firms, Mitsubishi Gas Chemical and Hitachi Chemical, control about 90% of the market for a specialty resin used to bond parts of microchips that go in to smartphones and other devices.
