近年来,为了建立海洋地声学模型而迫切地需要了解海底浅层沉积物声速与物理性质的相互关系.这种关系和地声学模型对于水声学、海洋沉积学、海洋工程等都是十分必要的.在南海北部大陆架和东海大陆架取得了相当多的海洋沉积物样品和测量资料.本文着重报道声速V_p,V_s和若干项重要的物理参数的关系,并建立相关分析图解试用于预报沉积物性质. In recent years, there is an urgent need to understand the relationship between the sound velocity and the physical properties of the shallow sediments in the seabed in order to establish acoustic models of the oceans, a relationship that is essential for acoustic acoustics, marine sedimentology, and marine engineering A great deal of marine sediment samples and measurements have been obtained in the northern continental shelf of the South China Sea and the continental shelf of the East China Sea.This article focuses on the relationship between the sound velocities V_p and V_s and several important physical parameters and establishes a correlation analysis map for prediction of sediment properties.
