In this thesis, the development of emulsion polymerization theory and related new technologies are comprehensively reviewed, and the synthetic technologies of acrylate latex modified by organosilicon both at home and abroad are also reviewed. based on the current development and research in this field, attentions of this study are focused on three ways for preparing novel acrylate latexes modified by organosilicons, that is, 1 ) the acrylate monomers are copolymerized with unsaturated silicons by emulsion copolymerization ; 2 ) a new latex with microphase separation morphology is synthesized, which shows a core - shell structure character ; 3 ) soap - free polymerization is explored for preparing a higher - performance latex using an unsaturated silicon monomer, different acrylates and a reactive emulsifier. by using techniques of delaying addition of organosilicon monomer and a hydrolysis inhibitor, the hydrolysis and condensation of 3 - ( trimethoxysilyl ) propyl methacrylate during polymerization can be effectively prevented, as a result, organosilicon content in the macromolecular chain is increased

將其解析解與具體的的抗震設防烈度和場地特徵周期結合起來，計算分析了成層地基中單樁的橫向地震響應，得到了以下結論： 1 ）上部結構慣性力對樁的橫向地震響應的影響不可忽略； 2 ）成層地基中的單樁的橫向地震響應主要受地震基本加速度、場地特徵周期、上部結構質量的影響，隨地震基本加速度、上部結構質量的增大而增大；場地特徵頻率越接近樁基自振頻率，樁基地震響應越大，等於自振頻率時，由於發生共振現象，樁基響應幅值最大； 3 ）樁土剛度比越大，樁土之間的相對位移的幅值越大； 4 ）樁頂固接的連接方式，可以有效地降低地震時單樁的橫向地震響應。Because of the resonant interaction between the reb electrons and the wave excitated by the embp instability, the reb electrons cannot transport continuously, but in form of current clumps. the transport velocity is close to the phase velocity of the wave
