含钼涂层钨材料在氦等离子体作用下的前期表面形貌演变研究

为了研究纳米绒毛的生成过程及内在的物理机制，采用磁控溅射镀膜的方式在钨片上镀有钼涂层 (Mo-W)。借助微观结构观察的手段分析了钨、钼块材以及钨-钼(Mo-W)样品在773K、1073K氦等离子体作用条件下的表面形貌演变过程。结果表明：钨、钼以及钨-钼(Mo-W)样品在氦等离子体作用下表面形貌演变规律基本一致；纳米绒毛及其珊瑚状前驱体是在尺寸相对较大的锥状结构上演化而来的。     

Order-homomorphisms on fuzzes

In this paper, basic properties of the concept of order-homomorphisms on fuzzes [4], which is a proper generalization of the concept of fuzz functions [1], are studied. Conditions for fuzz functions to be functions of Zadeh's type are obtained. Moreover, the concepts of continuous, closed and open order-homomorphisms are introduced and studied.     

拓扑空间范畴、拓扑FUZZ范畴与拓扑分子格范畴间的反射与余反射

从整体角度出发，证明了拓扑空间范畴Ｔｏｐ分别是拓扑Ｆｕｚｚ范畴ＴｏｐＦｕｚ与拓扑分子格范畴ＴＭＬ的反射与余反射满子范畴，ＴｏｐＦｕｚ是ＴＭＬ的反射与余反射（非满）子范畴．
