Epoxides, episulphides and ethylene imines also polymerize via similar cyclic onium ion mechanisms . 环氧化合物,环硫化合物和乙烯亚胺也可以按类似于环氧离子的机理进行聚合。
It is impossible to have a cyclic machine that completely converts the random molecular energy of heat flow into the ordered motion of mechanical work . 不可能得到一种循环机器能把热流的无序的分子能量完全转变为机械功的有序运动。
