Grinding head on, sliding imports of dual-use system linear guide, two-ball screw drive, to achieve the smooth running speed to eliminate mobile space (displacement).
磨头座、滑动系统采用进口的双直线导轨、双滚珠丝杆传动,以达到运行速度平稳、消除移动间隙(位移)。

In this paper, our aim is to discuss the extension of an extremal monotonic linear functional in the algebraic dualspace of a partially ordered linear space.
讨论了偏序线性空间的代数对偶空间上的端单调线性泛函的延拓性。

In this paper, we show that the isometry between the unit spheres of certain normed space and its dualspace can be extended to a real linear isometry on the whole space.
