英文摘要	Physical property models of gas hydrate-bearing sediments are studied and the amplitude-versus-angle (AVA) character of bottom simulating reflector are analysed. The relationships between elastic properties and gas hydrate/free gas concentration are presented based on the models of weighted time-average wood's equation, seismic wave propagation in three phases effective medium and elastic modulus. The AVA character of different models are calculated and analyzed. The analysis of AVA character of BSR shows that different reflection coefficient values but similar configurations of AVA curves are given for various combinations of different concentrations of gas hydrate and free gas.
