bond breaking

基本解释

This reaction includes old bond breaking, new bond forming and electron transferring between molecules.
此反应包括旧键断裂，新键生成以及分子间的电子转移。
Actually, quizzing the scholars about the probability of their bond-breaking is akin to asking a pair of newlyweds how likely it is that they will end up divorcing.
向奖学金得主询问毁约的可能性，如同在婚礼上不怀好意询问新人离婚的机率。
The other one of N(4)-C(5) bond-breaking ring rupture has the highest activation barrier of all the three channels and therefore it occurs less often than the former two.
另一条关于N（4）-C（5）键断裂直接开环的途径由于能垒较高，因此发生的几率较小。

If you get some of these in the upper atmosphere, a photon, an ultraviolet photon, has the energy capable of breaking this bond.
如果你把它放到大气层上，一个光子，一个紫外光光子，有能量可以破坏它的化学键。

So in order to rotate a double bond, you have to actually break the pi bond, so essentially what you're doing is breaking the double bond.
为了能够旋转双键，你必须打破一个π键，本质上我们要做的就是打破双键。

So, if we talk about dissociating h 2, we're going from the h 2 molecule, and breaking this bond right in half, so we now have two individual hydrogen atoms here.
那么，如果我们讨论的是离解氢分子，我们将从氢分子开始，使这个键断裂，一分为二，那么就得到了两个分开的氢原子。

断键
Some one defined the "effective reaction region " as a region of the new bond forming and the old bond breaking. This region is delimited on the MEP where the geometrical structure of reaction molecules would change mightily.
成键和断键发生在反应途径上一个较小的区域，该区域构成“有效反应区间”，即反应分子的几何构型发生强烈变化的区间。
