The reactions such as excitation, dissociation, decomposition occur for mutual collision, and generating active specy, (such as ultraviolet light, hydroxyl radical free radical, oxygen atom are free
Base, ozone, hydrogen peroxide etc.).Electron collision is the most important source of active specy, when electron and molecule collides, only electronics
When energy is higher than the Chemical bond energy of molecule, molecule can be acted.Therefore the premise that active specy generates is to generate
