The nano-silica partrcles are organic-modified by E-MA-GMA elastomer through direct solvent process,the organic-modify process mechanism was studied,and the dispersing of modified nano-silica particles in tetrachloroethane solvent and PBT were investigated.FIRT,TEM,SEM results indicated that the epoxy group of E-MA-GMA could react with the hydroxyl groups of silica surface,helped to reduce the interactions of nano-silica particles particles and improve the dispersion of nano-silica on PBT and the interfacia...

surface modification ；溶液法利用功能化弹性体E-MA-GMA对纳米二氧化硅进行表面有机化修饰改性，分析了表面改性过程机理，同时考察了改性后纳米二氧化硅在四氯乙烷溶剂和PBT基体中的分散情况；FIRT、TEM、SEM测试结果表明，E-MA-GMA的环氧基团与纳米SiO_2的—OH基团发生反应，降低纳米二氧化硅粒子间的相互作用力，改善了纳米二氧化硅在PBT基体中的分散，提高复合材料的相容性。

After analysizing the results of SSRFEM and centrifugal model test, someconclusions are drawn that, the depth of slip surface implies that the Bishopssimplied method cannot indicate the true failure mechanism for the slopes reinforcedwith piles. The rate of safety factors decreases with the pile spacing decreasing, andthe salty factor of the slopes is the largest when the reinforced piles are installed in themiddle of the slopes, regardless of pile head confining conditions, and the deflection,maximum bending moment and shear force in the reinforced piles in the criticalcollapse are the biggest meantime. The fixed and hinged head condition of the pilesresults in smaller bending moment in the piles than that in unrotated and free headcondition, therefore the restrained pile head condition is recommended in the design.

3不同特性与工况下抗滑桩与土体相互作用的数值分析与离心模型试验研究表明：采用简化Bishop法计算得到的滑动面不能反映抗滑桩加固边坡的破坏机理，抗滑桩设置在边坡中部和减小桩间距有利于提高边坡稳定安全系数，而此时抗滑桩在边坡临界破坏时的挠度、最大弯矩和最大剪力相对较大；桩头固定、铰接与桩头自由、平移相比，所加固边坡的整体水平位移及边坡临界破坏时抗滑桩的最大弯矩相对较小，而稳定安全系数则较大，因此在进行抗滑桩设计时应尽量选择桩头固定与铰接的型式，或对桩头进行锚固以改善抗滑桩的受力特性，提高边坡的稳定安全性状。

Aluminum/copper clad composite is produced by the method of aluminum/copper clad extrusion.In actual production,the interface between copper and aluminum separated from each other because of the untight bonding.

铜包铝线通常采用铜包覆铝坯料进行挤压生产，但实际生产中常出现因铜、铝固相结合不紧密而导致铜、铝界面分离的现象，为改善产品质量，提出采用低压压铸-冷挤压法加工制备铜包铝线。
