Abstract:In accordance with both the energy density function of complex signal and the energy distribution in time-frequency domain,author researched into two equivalent relations:(1) equivalent relation between the instantaneous frequency (or instantaneous phase) of sei-smic reflection wave group at delay place and the dominant frequency(or dominant phase),and (2) equivalent relation between instan-taneous frequency of reflection at any time and the real part of ba-rycenter frequency of wave-energy density function, In light of therelations.
