By low temperature (145K) deposition method, we prepared such flat Pb films on the Si (111) substrate over a wide thickness range (from 10ML to 32ML). The unique growth behaviors were investigated by RHEED, STM and ARPES. A critical thickness of 10ML is established, at which the atomically flat Pb films become stable at room temperature. Between 10ML and 20ML, the growth exhibits a quasi bi-layer growth mode. Above 21ML, a layer-by-layer growth mode was observed.

Sapphire from Shandon and Hainan commonly have the reaction border, we found out this reaction border enriched with Fe,Mg,and K by testing its components; We also studied the inclusion in the sapphire, and found many KC1 crystal grain with variety of size, a melt inclusion enriched with K,Si, is also found, this may suggest an assimilationary-magmatic course; Besides that, another minerl inclusions such as enstenite, magnetite, chromite, zircon are also found.

观察到了山东、海南蓝宝石普遍存在的反应边，并测试了反应边的成分，证实其以富Fe，Mg，和K为特征；研究了蓝宝石里面的包体，发现蓝宝石里面存在着大小不等的KCl的结晶颗粒，还发现了富K富Si的熔浆包裹体，说明其形成过程中有同化混染的贡献；此外还发现了斜方辉石，磁铁矿，铬铁矿，锆石的包体矿物。

The SI unit of transmission rate is the mol /(m2·s).

氧气透过率的SI单位为mol /(m2·s)。

Surface relief caused by the formation of lower bainite in an Fe-C-Si-Mn alloy has been investigated by STM. It was discovered that the subunit which is the lowest structural unit observed by TEM is actually made up of sub-subunits. The surface relief due to the formation of sub-subunit is tent-shaped, and of a non-IPS type, which indicates that the sub-subunit cannot be formed by shear. The height of relief is 60-140nm, and the maximum shape deformation is ca.
