接触表面

Water rings on the part of the inner surface just tangent with the impeller wheel, water ring coincides with the lower part of the inner surface contacts the top le**es (the le**es in the water in fact h**e a certain ring insertion depth).

水环的上部分内表面恰好与叶轮轮毂相切，水环的下部内表面刚好与叶片顶端接触（实际上叶片在水环内有一定的插入深度）。

And local anesthesia technology improvement: use cotton surface anesthesia first before use surface anaesthetic and advance nasal spray anesthesia astringent, in order to reduce cotton piece table linen of pain, While cotton piece table linen as far as possible when fully contact each all gaps.

局部麻醉技术的改善：使用棉片表面麻醉前应先用表面麻醉剂及收敛剂先行鼻腔喷雾麻醉，以减少棉片表麻时的疼痛感；同时棉片表麻时每次尽量全面接触鼻腔内所有缝隙。

Focal error signal of pickup head is achieved according to the Astigmatical principle, and that the optical non-contact probe system with the measurement ranges of 2um and the measurement uncertainty of 1.1nm is obtained. This probe system is immune to the variation of reflective ratios and curvature on the surfaces of samples via improvement of the signal process method.

其中根据光学象散原理得到激光读取头的聚焦误差信号，从而获得测量范围为2μm，测量不确定度可达1.1nm的光学非接触探头系统，通过改进信号处理方式，此探头系统可不受材料表面反射率变化的影响，并允许样品表面存在一定的曲率变化。

The method is based on the formation and deformation of double-stranded DNA membrane on a gold surface, which can encage reporter molecules between the gold surface and the double-stranded DNA, or keep them away from the gold surface.

致密的双链DNA分子层可以将电化学信号分子禁闭在金表面和双链DNA之间，或者将信号分子与金表面隔离开，使其无法接触裸金面。

The semi-ellipsoidal surface will be replaced by a hemispheroidal surface in the next device design. The required surface roughness of the metallic parts should be as low as ＝0.05μm.

下一阶段的人工椎间盘将以半球形面取代半椭圆球面设计，并且需提出加工制造与抛光处理流程，要求表面粗糙度达到＝0.05μm以下，使表面间有较平顺的接触行为。

To study the activation mode of LFA-1 on the NK cell surfuse, a platform based on optical tweezers was constructed to observe the molecular behavior of LFA-1. According to the results, the adhesion force between an NK cell and a polystyrene microsphere coated with anti-LFA-1 antibody was confirmed to be time-dependent.

我们利用光镊研究了NK细胞表面LAF-1的单分子行为，发现NK细胞与包被了LFA-1抗体的小球之间的结合力随二者接触时间的延长而增强，表明NK细胞表面LFA-1分子可能会受LFA-1抗体影响而发生局部聚集。

WC particles also can make the abrasive particles obtuse ,consequently reduce the cutting of abrasive particles to the coating.(7) The coating surface with unsmoothed units make the abrasive particles change moving direction . They can change the ploughing to rolling and bring light longitudinal vibration contributing to reducing the shearing force when the surface are worn by abrasive particles.

具有非光滑结构单元的复合层表面使参与复合材料磨损的磨粒改变运动方向，使之由滑动变为滚动，产生有利于减小切向力的法向微振动，减少磨粒和复合材料的接触面积和作用时间，从而大大减轻了磨粒对复合材料表面的损伤。

Summing up the reasons for the above situation is that there is the possibility of transformation between the status of two contacts (Cassie state and the Wenzel state) on super-hydrophobic surface, which can be promoted in different external conditions.

观察水在制备的超疏水涂层表面冷凝和蒸发情况，发现液滴可以在极易滚落和被紧紧粘在表面上无法下流，这两种状态之间相互转化，出现上述现象的原因可能在于超疏水表面上的两种接触状态（Cassie态和Wenzel态）之间存在着相互转化的可能性，不同的外界条件可以促使向不同方向的转化。

As the results, the surface with appropriately designed regular concave had better lubrication behavior, otherwise, the lubrication behavior would be worsened if the concaves were too large or small.

给出了一个研究规则凹坑对表面摩擦性能影响的三销环试验方案，考察了面接触下不同尺寸的规则凹坑对表面润滑性能的影响。

RESULTS:① Suspension of bare PS microspheres flocculated in the presence of lysozyme at 37℃ due to protein adsorption, which caused significant decrease in the turbidity of the suspension. Bare PS surface could adsorb 25.5 mg lysozyme per square meter.

结果：①37 ℃下未经预吸附改性的聚苯乙烯微球与溶菌酶接触后，因蛋白在聚苯乙烯表面吸附导致悬浮液发生絮凝、浊度显著下降的现象，原始聚苯乙烯表面蛋白吸附量达25.5 mg/m2。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
