摘　　要：4个岩芯的声-物理力学性质的垂向剖面表明,该海域沉积物的声-物理力学性质的受控因素是复杂的。其突变性质反映了沉积环境的重大变化对物理力学性质有重要影响,对声速的传播也间接发生作用。The vertical profile of acoustic-physicomechanical properties of four drilling cores show there are a few elements influencing the acoustic-physicomechnical properties of the sediments in the shallow waters off the Zhoushan Island lying on the coastal side of the East China Sea. It is revealed that the great variation in sedimentation process would be reflected as abrupt changes in the recorded properties and affect indirectly on the propagation of sound.
