The formed long and linear chain alkyl benzene changes into benzene methyl and alkene through - scission and monomolecular homolysis , and then benzene methyl shifts to the position of - carbon in the long chain alkyl benzene through h - transfers 已形成的长直链烷基苯通过分裂、单分子均裂形成苯甲基、烯烃，苯甲基通过氢转移到长链烷基苯的碳上，烯烃再与碳结合形成带支链的烷基苯。
Studies on the biomineralization of calcium oxalate crystals were performed in vitro using monolayer film and langmuir - blodgett film as templet . sem , esem , tem , afm , xrd and ft - ir were used to characterize calcium oxalate crystals obtained from a series of experiments 以单分子膜和lb膜作为模板，用sem ， esem ， tem ， afm ， xrd和ft - ir等表征方法，在体外研究了草酸钙晶体的生物矿化过程。
The phytic acid has the function of complexing with metal . it easily forms a protection film of single molecular on the metal surface to obscure the contact of oxygen with the metal and prevent magnesium alloy from corrosion in the process of electroplating 添加剂植酸与金属配合后,易在金属表面形成一层致密的单分子保护膜,能有效地阻止氧气与金属基体接触,从而可以防止镁合金基体在电镀过程中的腐蚀。
At last , chromatin structure is formed . with the development of single moleculer manipulation . much research work has been done on dna by optical tweezer , magnetic tweezer , micropipe , and so on . all these work has opened a new area in molecuer biology 随着单分子操作的实验技术的发展，人们通过光镊、磁镊、微吸管等等，研究dna分子的力学性质，探索dna与蛋白质的相互作用，为分子生物学的研究开辟了新的天地。
The organized assemble of the cds nanoparticles on the surface of the polydiacetylene film and its influence on the polydiacetylene film : the results of uv - vis spectra showed that when cds nanoparticles were assembled on the surface of the polydiacetylene film , the changing speed of cr became fast Uv - vis的结果表明硫化镉纳米粒子与聚双炔及其甘露糖衍射衍生物混合单分子层的复合后，单分子层对细菌的比色检测值变化的速度明显加快。
Results revealed that there are strong interactions between spreading molecules and pei soft cushion , and pei ' s existing made the microstructure of the monolayers very different from that of the films deposited from pure water subph ase , and surface patterned topography formed 结果发现成膜分子与软垫之间存在着强烈的相互作用， pei的存在使得单分子膜的存在状态与纯水亚相上的单分子膜相比发生了很大的变化，形成了图案化的拓扑结构。
