A steel bar is washed and dried, and then put into a glass pipe which is sealed to obtain stirring magneton; a mixed solvent of Gamma-methacrylate oxide propyl trimethoxy silane and methanol is prepared and added with an organic base to obtain a pre-bonding solvent; the stirring magneton is immerged into the pre-bounding solvent, and the outer surface of the glass pipe of the stirring magneton is bonded with a layer of silane substance with alkenyl; a reactive monomer mixture and a pore-forming agent mixed solvent are evenly mixed and then added into a container, the stirring magneton after the pre-bounding is put into the container which is sealed and then put into a water bath; after reaction, the container is removed, the stirring magneton coated with a polymer is taken out and put into a extractor and extracted by using a solvent; or the stir bar is immersed into the solvent till no impurity can be checked in the solvent, thereby obtaining the product.

将铁条清洗干燥，放入玻璃管内，密封得搅拌磁子；配制γ-甲基丙烯酸氧丙基三甲氧基硅烷与甲醇的混合溶液，加入有机碱得预键合溶液，将搅拌磁子浸入预键合溶液，在搅拌磁子的玻璃管外壁键合一层带烯基的硅烷化物质；将反应单体混合剂和致孔剂混合溶液混匀后倒入容器中，将预键合后的搅拌磁子放入容器，密封后置于水浴中，反应后除去容器，取出涂有聚合物的搅拌磁子，置于提取器中，以溶剂提取，或将搅拌棒置于溶剂中浸泡至溶剂中无杂质检出，得产物。

By using three broad distribution standards of polytitanocarbosilane whose number average molecular weights are determined by VPO, the calibration equation of gel permeation chromatography of the preceramic polymer polytitanocarbosilane which generally haslow average molecular weight and high branching degree was established as follows: ln M=

采用以气相渗透法测定了数均分子量的宽分布含钛聚碳硅烷作标样，通过计算机辅助建立了具有较低分子量和较高支化度的陶瓷先驱体聚合物——含钛聚碳硅烷的凝胶渗透色谱校准方程lnM＝20.9－0.843T。

A self-assembled monolayer film of tolane was fabricated in aqueous solution by using silane coupling agent.

用硅烷偶联剂3-氨丙基－三乙氧基硅烷，通过自组装反应在石英基板表面制备了含有二苯乙炔基的自组装单层膜。

The modified surface with a high friction coefficient becomes hydrophilic.The main reason is that: there is a basic photoreaction of oxygen under UV radiation,in which atomic oxygen may highly be generated.Then the oxygen atom reacts with trace amounts of water to form hydroxyl.

其机理为：在紫外照射条件下氧气发生光化学反应形成氧原子，氧原子和微量的水发生反应形成羟基，羟基和烃发生夺氢反应形成硅烷的烃自由基，同时硅烷的烃自由基会发生β-scission裂解形成较短链的自由基。

By comparing of different treating methods of wood-fiber: treated with silane coupling agent, NaOH solution and silane coupling agent, grafted by poly, it can be found that grafted wood-fiber evenly distributed in PVC matrix. Grafted wood-fiber and PVC matrix had a better interfacial compatibility than that of the ungrafted wood fibers, which was verified by scanning electron microscope observation.

比较了硅烷偶联剂处理、氢氧化钠溶液浸泡与硅烷偶联剂双重处理，接枝改性等3种木纤维表面处理方法对木纤维／PVC复合材料界面及性能的影响，通过扫描电镜照片发现接枝改性木纤维在PVC基体中分散更均匀，与PVC界面相容性好。
