The growth of perylene and tetracene on Ag (110) has been studied by the ultraviolet photoemission spectroscopy and low-energy electron diffraction.

Sulfide layer was made on the surface of high speed steel (W6Mo5Cr4V2) by means of low temperature ion sulfurization. The tribological properties of the sulfide layer under dry sliding were investigated on an MM 200 friction and wear test rig. An atomic force microscope and a scanning electron microscope equipped with an energy dispersive spectrometer attachment were adopted to analyze the morphologies and compositions of the original and worn surfaces of the sulfide layer. The phase structure of the sulfide layer was determined by X ray diffraction.

采用低温离子渗硫工艺在 W6 Mo5 Cr4 V2高速钢表面制备了硫化物固体润滑层，在 MM- 2 0 0型摩擦磨损试验机上对渗硫层的摩擦学性能进行了干摩擦试验研究，用原子力显微镜及扫描电子显微镜和 X射线光电子能谱分析渗层表面、截面、磨面的形貌及成分，用 X射线衍射仪分析了渗硫层相结构。

We have epitaxially grown ultrathin Pb and Co films on the Cu(111)surface bymolecular beam exitaxialgrowth technique,and studied in detail the growthand surface alloying of submonolayer Pb on Cu(111),the shift of Pb 5d core levelbinding energy on Cu(111),the surfactant-assisted epitaxial growth of Co on Cu(111)using Pb as a surfactant,and the spin exchange splitting of ultrathin Co films onCu(111)using synchron radiation photoemission spectra as well as Auger electronspectraand low energy electron diffraction.

利用分子束外延生长技术在单晶Cu(111)表面外延生长了超薄Pb和Co膜，并利用同步辐射光电子发射谱，结合俄歇谱和低能电子衍射，详细研究了超薄Pb在Cu(111)表面的生长、表面合金化，Cu(111)表面Pb的5d芯能级位移，以Pb作活性剂时Co膜的活化外延生长，以及超薄Co在Cu(111)表面的自旋交换劈裂，得到了一些有意义的结果。

In an ultrahigh vacuum chamber with a base pressure of 1 x 10-10 torr, we have used Low Energy Electron Diffraction and Temperature Programmed Auger to study the effect of adsorbates on the surface structure of Nb(111). That is, in O/Nb(111) systems, we observe the structure of the surface with LEED to see if any surface reconstruction occurs after annealing and analyze the structure.

在超高真空(约1 x 10-10 torr)的环境下，我们利用了低能量电子绕射(Low Energy Electron Diffraction， LEED)、可程式控温欧杰能谱(Temperature Programmed Auger， TPA)，来研究氧覆盖层对於铌基板的影响，亦即PO/Nb(111)表面系统中，再利用LEED观察是否有任何表面重构的现象发生并详细分析此结构。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
