松动件定位是核电站一回路松部动监测系统（LPMS）中一个重要的内容，其中时延的精确计算是提高精度的关键。用连续小波变换方法确定碰撞信号的时间延迟，并用三角形定位方法进行了实验，结果表明小波变换对随机噪声有较好的抑制作用，奇异点位置确定比较精确，定位精度有所提高。

Location of the loose parts is a important content in the nuclearloose parts monitoring system. The exact calculation of the time delay is the key step to raise precision. The time delay with continuous wavelet transformation are calculated, and experiment with triangle location is done. The result shows that wavelet transformation can dam the random noise and get the more exact location of the odd point.
