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镜（SEM）、热分析（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中结构性能的变化。
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. 经多年对冲击脉冲计的使用，积累了较丰富的经验，同时在轴承的故障诊断中取得了较好的效果。
