The wear resistance, conductivity and mechatronic reliability of the films were studied by contact atomic force microscope (AFM), electric force microscope (EFM) and conductive AFM. The failure mechanism of pits formed and the reason for conductivity changed of DLC films were examined.展开更多
In this paper, a rigidity theorem of hypersurface in real space form will be given. In addition, we obtain rigidity theorems of submanifold in sphere which improve the result of Hou and Xu.
