| Abstract: | Based on the invariance of elastic wave equation with respect to Galileo's coordinate transformation,this paper has derived the tranformation equation of elastic wave parameters (wave velocity,wave frequency and wavelength). An universal expression of Doppler's effect was obtained. A preliminary discussion on the transformation of elastic intensity is presented, too |
