  • The way the chemical bond arises from physics and certain accidents.
    这些化学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.

  • 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，他们已经表明，这些氨基酸可以相互反应，形成与通常维持三维形状的蛋白质不同的化学键。

    • 原声例句

  • 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，既然提到了共价键，我们应该还可以,给化学键下一个更普遍的定义,那就是告诉我们氢分子能量应该更低,与两个分开的氢的单原子分子相比。

  • So, we're going to start with talking about bonding, and any time we have a chemical bond, basically what we're talking about is having two atoms where the arrangement of their nuclei and their electrons are such that the bonded atoms results in a lower energythan for the separate atoms.
    那么，下面我们将从成键开始讲起，无论什么时候我们有一个化学键，基本上我们所讨论的,都是如何安排两个原子的原子核的位置,与电子的位置使得成键的两个原子,最终比分开时的能量更低。

  • 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.
    关键在于，这种能量与熵之间的平衡,确定了平衡的条件，在化学中能量涉及键能，而熵和无序有关,即有多少可能的不同组合或者形位，二者的平衡会告诉我们平衡态是什么样子。
