辐射可固化涂层在空气中进行紫外光照射，其固化速率随光引发剂组份的增加开始近似线性增大，到某一点后出现突跃．通过对氧气存在下的聚合机理的研究，认为上述现象与氧气引起的自由基终止以及固化过程中的氧气消耗速率有关．根据文中推导的关系式作出的示意图与实验数据基本吻合．
Radiation-curable coatings are irradiated with UV light in air and their curing rate increases approximately linearly with increasing photoinitiator composition, with a jump after a certain point. By studying the mechanism of polymerization in the presence of oxygen, the above phenomenon is believed to be related to the termination of oxygen-induced free radicals and the oxygen consumption rate during curing. According to the text derived from the relationship between the schematic and experimental data are basically consistent.
