Adhesives - testing methods of bonding strength of adhesives - part 4 : guidelines for the surface preparation of adherends excluded metals and plastics 粘合剂.粘合剂粘合强度的测试方法.第4部分:不包括金属和塑料的被粘物表面制备指南
We add the special layer in the outer shell of the glove to prevent slide when use . you can catch the res in the creamy liquor , even the moving fish 手套的触物表面加涂了特殊防滑层，可在滑腻的洗涤液中拿牢洗涤物或可抓牢游动的活鱼。
Instructions : neutral cleaner . it contains special formula and can dissolve and decompose the dirt quickly , thus to achieve the best cleaning result without damage the surfaces 产品说明：该产品为中性外墙面清洁药剂，特殊的配方可以是使被清洗物的污垢迅速溶解和分离。从而达到良好的清洗效果并不破坏被清洗物表面。
It is proved by the simulation that the temperature of samples can be estimated from the thermo - couple placed on the cover glass and the planar temperature distribution of the cryostage is approximately uniform 分析结果表明：可以利用布置在盖玻片上表面的热电偶测量并推算实验样品层的温度；低温台载物表面温度均匀。
As the total negative surface charge of such complexes matches the surrounding charge density of the matrix , the sds - protein complex stops migrating and remains stationary , as typical of steady - state separation techniques 当复合物表面总的负电荷与周围基质的电荷密度一不能致时，与典型的稳态分离技术相似， sds -蛋白复合物则不再迁移而保持固定。
Electromagnetic wave shielding fabric was prepared by in - situ chemical polymerization of aniline in the presence of cotton substrate , using hydrochloric acid as the doping agent and ammonium persulfate as the oxidant 摘要以盐酸为掺杂剂，过硫酸铵为氧化剂，在棉织物表面采用现场吸附聚合法生成一层导电聚苯胺，由此设计出一种具有良好电磁屏蔽效能的织物。
They are widely used in polishing the surface aluminium , copper and iron pressed articles , polishing varieties of metal works , removing hair or stab of pressed articles , and sandblasting or grinding of knives and pressed articles 广泛应用于铝压铸件及铜铁铸件的表面精加工处理，各种金属表面的喷砂打磨，铸造工件的除毛边毛刺，刃物表面锻造制品表面的喷砂打磨等。
Spurt water column not only is a good coupling medium of ultrasonic , but also can get rid of impurity , such as power , vapor and oil film on the surface of the measured object , so this sensor can adapt various environments 因为水柱不仅是超声波传播的良好介质，还可将被测物表面的粉尘、水汽、油膜等杂质吹走，使系统具有良好的环境适应能力。在恶劣环境下进行位移测量时，该传感器具有其他仪器不可比拟的优越性。
Grinding wheel continues with an infinite number of hard , sharp and refractory grits on edge surface at a high speed of swing operation to cut and grind over the surface of work piece , and unceasing self - sharpening grains and pore continue to grind a tool for every kind of material 砂轮是经由高速回转运作中，以其在外缘表面植无数上千万之硬锐耐温之小磨粒连续在工作物表面切削磨除，且不断的自生锐利颗粒与磨屑空隙气孔，继续对各种材料做磨削工作的一种研磨工具。
