摘要
通过对海洋沉积物声速及其物理-力学参数相关性的初步分析和研究,可以找到估算沉积物压缩波速Vp和切变波速Vs的经验式,最终为海底沉积物的性质进行声学遥测、为发展海底参数声遥感服务。本文给出了7个较为理想的回归方程。沉积物的物理参数与Vp有密切的关系;力学参数对Vs的预报有较大的作用。若增加物理参数作为修正项,其效果更佳。
Recently, a vast amount of data have been obtained by the authors from various physiographic areas of the northern South China Sea. By means of the second order multinomial regression analysis, with physical and mechanical parameters as independent variables and measured velocities as dependent variables, some satisfactory univariate and bi-variate regression equations have been acquired and the results are presented in the present paper.
