These amine substituted acid may polymenze in an analogous manner to unsubstituted oxo-anions . 这些胺取代酸可以与未取代的氧络阴离子相类似方式聚合。
In the polymerization systems studied, segmental rearrangement is the important rate-determining phenomenon . 在已研究过的聚合体系中链段重排是重要的速度决定步骤。
With large amounts of monomer, bulk polymerization often takes very turbulent and even explosive form . 用大量的单体进行本体聚合,其反应常是十分激烈甚至是爆炸式的。
Elsewhere, two plates may shift toward each other and converge along a deepsea trench and island arc . 在别的地方,两块板块又可能相向移动而沿着深海沟和岛弧逐渐聚合。
In nuclear fusion, a pair of light nuclei unite (or fuse) together, form a nucleus of a heavier atom . 在核聚变的情况下,一对轻核合并(或聚合)在一起,形成一个较重的原子核。
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。
Impurities that promote deterioration of polymers can be foreign materials, such as residues from polymerization catalysts . 促使聚合物劣化的杂质可能是外加的物质,如残存的聚合用催化剂。
Another distinction often made in the literature of numerical taxonomy is that between divisive and agglomerative approaches . 在文献的版值分类方法中,还存在另一个区别,即划分法和聚合法。
The process of fusion of two identical images taken from different angles can be accomplished by the naked eye or instruments . 以不同角度拍摄的两个相同影象聚合的过程,可用肉眼或仪器完成。
