The compositions are used as cavitation erosion- resistant linings of plain bearings that comprises a metal backing of steel, a sinter layer of sintered bronze on the backing, and a bearing of the composition on the sinter for example oil lubricated bearings where low friction is essential as ...
In a flat knitting shaped part with two spaced knitted surfaces, a top surface (22) and an underside (24) zones of the pile threads (6) are arranged form the cushion elements. The pile threads (6) are constructed as monofilament and in the tuck loops of the knitted surfaces (22, 24)...
For a regular curve on a surface in the unit 3-sphere, we have a moving frame along the curve which is called a spherical Darboux frame. We induce two special vector fields along the curve with respect to the spherical Darboux frame and investigate the singularities of extrinsic flat great ...
athe flat surfaces are to be brought in contact with the cells and the crushing is to be continued until an applied force of 13KN is reached.once the maximum force has been obtained it is to be released. 平面将被带来与细胞联系,并且击碎将继续,直到13KN应用的力量是最大力量得到了它将被发布...
The Burlytic® process is highly discriminating in that it is inherently edge-seeking. Not only are burrs quickly removed from edges, but surfaces often result in an improved finish. The process is especially suitable for parts that:
aThe surface grinders are for grinding all kinds of flat work, or work wish plan surfaces which may be operated upon either by the face of a grinding wheel. These machines may have reciprocating or rotating tables. 表面研磨机是为研各种各样也许被管理在二者之一由一个砂轮的面孔的平的工作或者工...
