Hydrophobically associating water-soluble polymer-based synthesis is difficult and not easily characterized, in part to hydrophobic chains connected to the water-soluble polymer, the general use of micellar copolymerization, or the use of the large surfactant monomer to copolymerization, polymer micelles need in the system by adding a large number of surface-active agent, which, after an increase of the complexity of the process.

疏水缔合型水溶性高分子很难合成，且不易表征，把疏水部分连接到水溶性聚合物链上，一般采用胶束共聚合或者使用具有表面活性的大单体进行共聚，胶束聚合需要在体系中加入大量的表面活性剂，这就增加了后处理过程的复杂性。

Data of tooth surface before and after wear were both obtained through laser scan system. The images were then reconstructed by SURFACER software.(2) C language program used of improved iterative closest point algorithms was developed to registrate imagines before and after wear. Standard plan was defined to the overlapped imagines after registration, then wear quantity was measured.￤ear was imitated by tooth brush machine which was made by STOMATOLOGY COLLEGE FORTH MILITARY MEDICAL UNIVERSITY.

应用三维激光扫描仪采集牙模型的表面数据，在计算机中用SURFACER逆向工程软件重建牙表面；②运用最近邻点迭代匹配算法加以改进，编制 C语言程序，配准磨耗前后的三维图像，在确定基准平面后，计算磨耗前后的体积变化量；③用口腔医院自制刷牙机进行模拟磨耗，用传统称重法，通过电子天平测试件的重量变化，用失水法计算测试材料的密度，换算成体积。

Based on the rigorous analysis of the kinetic process of both primary and secondary electrons, the related surface charges were analyzed, and the energy gain of emitted electrons was proportional to the square of the ratio between the tangential and normal component of electric field. In this process, the image force of mirror charges would result in an energy loss. Meanwhile, the effect of field alternation of power frequency ac voltage on electron movement could be ignored.

在前人工作的基础上，进一步严格推导了场致一次发射电子和二次电子的运动方程，分析了电子发射引起的绝缘材料表面带电，表明电子发射后的能量增益正比于场强的切向与法向分量比值 F /// F ^的二次方；同时考虑了在电子发射和运动过程中电荷镜像力的作用，并探讨了交流电压下表面带电的情形，认为当考虑电荷镜像力的作用时，电子的能量增益可能变小，而工频交流电压下电场交变对电子运动的影响可以忽略。

The results show that the dispersity order of phosphates from strong to weak is as follows: sodium hexametaphosphate, sodium pyrophosphate, trisodium phosphate.

结果表明：磷酸盐对这4种矿物分散效果由强至弱的顺序为：六偏磷酸钠，焦磷酸钠，磷酸三钠；六偏磷酸钠增大铝硅酸盐矿物颗粒表面电位的绝对值，从而提高了颗粒间静电排斥作用；同时，六偏磷酸钠吸附于铝硅酸盐矿物表面后，加剧了颗粒之间的空间位阻效应，使颗粒间产生较强的位阻排斥力。

Quantitative analysis of protein adsorption: The PS suspension containing lysozyme was subjected to ultracentrifuge (15 000 r/min) to collect clear aqueous solution. The lysozyme concentration in the clear solution was measured by spectrophotometry at 280 nm. The amount of protein adsorbed on PS surface was calculated based on the decrease in the protein concentration in the supernatant solution.

蛋白吸附定量分析：采用高速离心(15 000 r/min)法从含溶菌酶蛋白的聚苯乙烯悬浮液中分离出上清液，用紫外(280 nm)分光光度法测定经聚苯乙烯微球表面吸附后，液相蛋白质量浓度的下降值，由此推算蛋白在聚苯乙烯表面的吸附量。

Use: suit for polishing different mirror surface of dishware of stainless steel, watchcase, and steel pipe. The mirror surface effect can be finished after polishing the disfigurement of oxidation layer on the metal material surface.

用途：適合不锈钢餐具、手表表壳和不锈钢管材等其他不锈钢工件的研磨及镜面抛光，除去不锈钢板材表面的氧化皮和缺陷，经研磨抛光后的表面可达到镜面的效果。

The results show that microstructure of the surface layer after electron beam irradiation consists of four zones,i.e.surface melting zone,phase transformation hardening zone,transition zone and base alloy.

研究结果表明，Cr12MoV模具钢经电子束表面熔凝处理后的显微组织可以明显地划分为四个区域：表面熔化区、相变硬化区、过渡区及合金的基体。

The adsorptions of SiH_2, SiH_2 with a hydrogen adatom (SiH_2+H) and SiH_2 with two hydrogen adatoms (SiH_2+2H) on the Si (100) surface near SDV structure have been calculated. Three possible sites are found in each case, and the presenting of hydrogen may reverse the relative stability of these sites.

本文首先计算分析了SiH_2、SiH_2+H和SiH_2+2H等硅烷分解后的产物在硅表面的吸附特性，我们发现每种情况都有三个可能吸附的位置，并且表面附着氢原子的出现可以造成这些吸附位置相对稳定性的逆转。

Otherwise, an intermediary allylamine deposition was covalently linked to the oxide layer by glow discharge, the covalent binding of bioactive protein to the free terminal NH2 groups using glutaraldehyde as a coupling agent was followed.

并利用丙烯胺的电浆处理在钛金属表面键结上胺基(-NH2)的官能基，之后再以交链剂戊二醛来固定生物活性胶原蛋白於低温电浆处理后的钛金属表面。

B. Spreads the cloth: Spreads evenly with the highly effective moisture absorption cloth wipes the surface, after skin drying waits with to do the cloth to carry on the antiquing then.

B。 涂布：用高效吸湿布均匀涂抹表面，待表面干燥后用干布进行打光即可。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
