The connectedness of the non-empty closed subsets hyperspace with locally finite topology is discussed and a cardinal function called discrete degree is introduced.

讨论了赋予局部有限拓扑的非空闭子集超空间的连通性，还引入了一个对讨论局部有限超拓扑有用的基数函数，称为离散度。

In this paper the local compactness of the nonempty closed subsets hyperspaces with locally finite topology is discussed.

本文讨论了赋予局部有限拓扑的非空闲子集超空间的局部紧性。

Then, by virtue of frequency domain multiplier method, we prove that the closed loop system with both a locally distributed feedback con.

进而利用频域分片乘子方法，在所论梁系统同时具有分布反馈控制和边界反馈控制的条件下，证明其相应的闭环系统能量指数稳定。
