波函数

Based on the Betti-Rayleigh dynamic reciprocal theorem, the reciprocal property of the Green function is demonstrated; and the analytical solution of soil vibration subjected to moving loads is deduced. By means of double Fourier integral transform, the problem is firstly transformed into wave number-frequency domain, which makes it very convenient to derive the solution and furthermore to analyze the frequency characteristics of soil vibration.

The curve of third harmonic sound pressure level(SPL3)is alsoa "periodic function".The period length is about"first resonancefrequency" of the tube Δf=f0=c0/(2L).The magnitude of SPL3 canbe predicted by Coppens theory(with one of the parameters modified).
