The changing of the structure and properties of UHMWPE fibres during super drawing were studied by means of SEM, DSC, WAXD and sound pulsimeter.

还借助扫描电子显微（SEM）、析（DSC）、广角X射线衍射（WAXD）、声速等手段研究了UHMWPE熔纺丝在超拉伸过程结构性能变化。

By means of ballistic pulsimeter operation of recent years, the relative wealth of experimence is accumulated. The better effect in bearing failure detection is obtained simultaneously.

多年对冲击脉冲计使用，积累了较丰验，同时在轴承故障诊断取得了较好效果。
