%X The same results are obtained through different experimental methods on varios rocks saturated with different fluids. The results reveal a common physical characteristic of saturated porous rocks, that is,they have strong dependences on time and temperature. The experimental results also reflect the relaxation progress of thermal activation of rocks. Wave theory of porous media is introduced to this theoretical Biot model. Moreover,the dependences of attenuation on strain amplitude are also obtained.
