The Mobula also includes four exterior hulls to enable its enormous payload float smoothly on the surface of the water, which not only expands to hold the craft but also deflates to minimize drag during the flight, thanks to the built-in hydrofoils.

该Mobula还包括四个外部船体，使巨大的有效载荷浮法顺利表面的水，这不仅扩大举行工艺，而且还最大限度地减少阻力经济学家谢国忠在飞行，由于内置的水翼。

HIV-1 nef downregulates the expression of cell surface HLA-1 molecule as well as induces cell apoptosis.

HIV-1 nef下调细胞表面的HLA-Ⅰ类分了及诱导细胞凋亡。

The results showed the bacterial supernatant and periplasm containing NKAT2 scFv were able to bind the NKAT2 receptors expressed on cell surface,but NKAT4 scFv failed to bind to NKAT4 receptors.

结果显示，含NKAT2－scFv的细菌上清及胞质提取物均可识别到表达在细胞表面的NKAT2受体分子，但含NKAT4－scFv的细菌上清及胞质提取物均未成功

The photodegradation of PAH on fly ash surfaces follows pseudo first-order kinetics under the irradiation of simulated sunlight with UV-B, whereas inner PAH of fly ash is photostable.

燃烧过程中产生的烟灰中含有一定浓度的PAH，在模拟太阳光中的UV-B部分的照射下，烟灰表面的PAH的光解符合一级动力学方程，而烟灰内部的PAH比较稳定，难以光解。

Because the atomic affinity energy of Ca-O and Be-O is lower than Mg-O,The Ca and Be aggregating on the surface of liquid Mg will priorly combined with O,forming compact oxides of Ca,Be and alloys of elements,which prevent Mg alloys from burning.

由于Ca，Be与氧的原子亲和能低于镁与氧的亲和能，聚集在液体表面的Ca，Be将优先与氧结合，生成致密的镁与合金元素的混合氧化物，阻止镁合金燃烧。

Over the years, Treffert has developed and finetuned the Treff Guard Technology for wood surfaces thus giving optimum protection to wooden floors while preserving the finished products' reparability.

魏尔：多年来，我们开发并调整了应用于木材表面的 Treff Guard 技术，从而为木地板提供了最佳的保护并保留了成品的可修复性。

Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

最后全文结合研究反应后催化剂表面的XPS光电子能谱推断了该体系降解污废水可能的反应机理：在酸性条件下，石墨双阳极产生的O_2被多孔扩散性石墨阴极还原成H_2O_2，并通过扩散传质作用在催化剂的表面活性中心分解为强氧化性中间产物·OH，强氧化性攻击有机物，使其降解为小分子有机物或CO_2和H_2O，催化剂在体系中即起催化作用也起吸附、絮凝作用。

A machine component comprising: an elongated base plate with side edges, a linear actuator assembly having two parts which can move away from and toward each other, first mounting means on said base plate, said mounting means supporting one part of said assembly, a slide plate rectangular in cross-section and having parallel straight side edges, two elongated guide members each having a rectangular slot adapted to slidingly receive the edge of the slide plate, each elongated guide member including a lowerpart and an upper part and means for securing them together, the lower part having means for attachment to the base plate, said rectangular slot having (1) a first side wall adjacent to and parallel with the base plate, said first side wall being definedby a surface of said lower part,(2) a second side wall defined by a surface of said upper part, and (3) a bottom wall defined by a surface of one of said upper and lower parts, the upper and lower parts having oblique mating surfaces such thatlongitudinal meovement of one part with respect to the other causes the parts to separate from or approach each other in a manner to change the width of said slot, and second mounting means establishing a connection between the slide plate and the other part of said assembly.

有一长条形底座与身边的边缘，一个线性驱动器装配有两个部分，可以离开，彼此之间，首批意味着在说底座、说安装方式支持之一说总成，一个矩形截面板、平行直边棱、两种细长的引导会员都有一个矩形槽适应slidingly收到边缘的细长板，每一个lowerpart引导会员包括一个上方和手段，确保他们在一起，下方附件的方式，在底座，说矩形槽有(1)第一次侧墙毗邻，平行底座，一边说：definedby墙表面说下方，(2)第二次侧墙表面的定义，并说上方(3)底壁由一个表面的上部和下部零件，说上部和下部阀部件表面的thatlongitudinal拥有斜meovement这样的一部分的原因部分可以分离或接近对方的方式来改变宽度的槽，第二次安装方式，建立连接板之间，另一部分说总成。

The native oxides on CdSe surface could be reduced to elemental Selenium by a HF etching process. Bombardment using 100eV Ar〓 ions with a dosage of about 1×10〓 ions/cm〓 could remove all the elemental Selenium, which results in a normal stoichiometrical surface CdSe.

实验观测到HF刻蚀可以将CdSe半导体表面的Se氧化物还原为元素Se.100eV的Ar〓离子轰击可以除去HF刻蚀后在表面还原生成的元素Se，从而清洁样品表面，保证了表面CdSe的化学计量比。

The Ag adsorbed on TiO2 nanoparticles could be eluted completely by mixed solution of nitric acid(1 mol/L) and sulfourea(2 g/L).
