| 摘 要： | 声学反演方程是声学探测沉积物物理参数的基础方程。基于声学理论和统计理论的声速反演沉积物物理参数的两种模式,运用南海海底沉积物声学物理数据验证、比较了两种反演模式,以反演孔隙度、含水量为例,得出基于双参数经验方程反演模式的适用性较强,但精度有待于提高;基于声速理论的反演模式反演南海海底沉积物物理参数有待于进一步完善。

| Abstract: | The acoustic inversion equationis basic in acoustic measurement of physical parameters of sediments. Two kinds of acoustic inversion models of physical parameters based on acoustic theory and statistical theory are studied. Acoustic and physical measurement values in seabed sediments of the South China Sea shelfare applied to testingand comparing the two models. By instancing the physical parameters of porosity and water content,the inversion model based on double-parameterem pirical equationis well applicable but to be improved ininversion precision. The inversion model inferred by acoustic theory is maturatingininversing physical parameters of seabed sediments in the South China Sea. |
