S PTFE samples reinforced by different content of carbon fibers ( CFRPTFE) were prepared by cold moulding and green mould sintering, and the mechanical properties, such as friction, wearing resistance and microstructure of the samples were studied.
通过冷压成型和烧结固化工艺制备了不同配方下碳纤维增强聚四氟乙烯（PTFE）试样，并对其进行了机械性能、耐磨损性能测试，用扫描电镜进行了组织结构观察。
The results show that the mechanical properties of alloys decrease with increasing LaF 3 addition, and the ability of anti friction and wear resistance of alloys increases with increasing LaF 3 addition, especially at high temperature.
研究结果表明，合金的力学性能随LaF3添加量的增加而降低，但其减摩耐磨能力随LaF3添加量的增加而提高。
Maglev is very suitable for being put into the tube that will be evacuated, namely vacuum tube. Because both mechanical friction and air resistance are eliminated, the vehicle in such kind of evacuated tube could run much faster than airplane.
这种磁悬浮车辆适合放置于管道中，再把管道中抽成一定真空，由于同时消除机械摩擦和空气阻力，其运行速度能比飞机快许多倍，此即真空管道运输系统。
