| 中文摘要: |
| 针对金属跌落零件碰撞金属板产生的冲击信号，比较了时域初始过零点法和能量比法两种时间延迟估计方法；比较了三角形定位法和线性陈列法两种定位方法．最后分析了存在的问题，并提出了改进途径。 |
| 英文摘要: |
| On the problem of estimating the time delay of the impact signal causedby the loosened metallic parts, the comparison of the Initial Cross Zereo Method withthe Energy Ratio Method deveIoped had been done. On the localization, the TrianularMethod and Linear Array Method had been applied, some friut results had been gotten. |
