Scratch test revealed that the adhesion strength between the GLC film and UHMWPE substrate was as high as 90N. The volume wear rate of GLC coated UHMWPE was 1.6×10^(-17)m^3/, which is 19 times reduced.

结果表明：磁控溅射法制备的GLC薄膜与基体结合力大于90 N，且对表面粗糙度没有影响；表面镀覆GLC薄膜的体积磨损率为1.6×10^(-17)立方公尺/，是UHMWPE的1/19。

The results of Monte Carlo simulation disclose that in large range of nitrogen fugacity the solubility of the interstitial nitrogen in αFe obeys Sievert's law. This range is much larger than that in γFe-N system. The results also show that in order to get the same level of interstitial nitrogen solubility in αFe-N system during solid state nitride, larger nitrogen fugacity is needed at the lower temperature.

该逸度范围比面心立方结构的Fe-N体系中大得多；由模拟计算结果还可知，在固体渗氮过程中，若要使合金含有同样浓度的固溶氮，渗氮温度较低时应保持较高的氮分压。

And the wheel's kick and the wind's song and the white sail's shaking,And a gray mist on the sea's face and a gray dawn breaking.I must go down to the seas again, for the call of the running tideIs a wild call and a clear call that may not be denied;and all I ask is a windy day with the white clouds flying,And the flung spray and the blown spume, and the sea gulls crying.I must go down to the seas again to the vagrant gypsy life,To the gull's way and the whale's way where the wind's like a whetted knife

Due to their applications in magnetic, optical, electronic and catalyst, polynuclear lanthanide clusters are of importance. In this part, a series of nanowheel-shaped nonanuclear lanthanide clusters,〓〓(Ln=Sm~Tm; BA=benzoylacetone), were prepared and characterized. Each complex can exist in three phases, i. e., cubic, tetragonal and triclinic.
