Abstract: The testing systems of Rayleigh wave both in steady-state and transient-state and the calculating principle of dispersion curves of phase velocity of Rayleigh wave are simply described first. Then, the theoretic presupposition, on which the dispersion curve from SASW method may be equivalent with the result from steady-state method, is pointed out. An optimized coherence-function method, by which the testing effect of SASW method can be improved by means of testing procedure control, is proposed at last.

Key words: rayleigh wave, dispersion curve, equivalence, SASW method, optimized coherence-function.
