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。

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。
In other words, they flipped a switch, which allowed them to change the electrical conductivity of the silicon without making or breaking a single chemical bond within the surface.
或者说，他们扳动了一个开关，改变了硅的电导率，而不需破坏表面上的任何化学键。
In femtochemistry, we describe the application of femtosecond lasers to studies of chemical reaction processes, isomerization, breaking and forming of the bond, and the dynamics of transition states.
