Wavelet analysis on acoustic signal propagation characteristics
Select 7 kinds of different diameter waveguide rod, carried out the breaking-lead experiment on the center of section and the circumference of length with 3.2m,2.5m,2.0m,1.5m,1.0 m. Then concluded the change of P -wave separation and amplitude by the diameter and the length .Advanced the principle for choosing in practice. By analysing the signal timedomain, calculated the speed of the acoustic signal transmitting in the waveguide rod. Put forward that the speed changes, can effect the location. This electronic document is a live template. The various components of your paper title, text, heads, etc. are already defined on the style sheet, as illustrated by the portions given in this document.
