Meanwhile, the existence of the acousticattenuationcoefficient benefits the axial resolution.
同时,声衰减系数的存在有利于轴向分辨率的提高。
2
Two new medium parameters related to acousticattenuation are introduced and an acoustic propagation coefficient is defined.
本文引入两个与声衰减有关的介质参量,定义了声传播系数;

The rock acoustic parameters in this paper include wave amplitude, spectral amplitude, spectral area, spectral density, wave velocity and attenuationcoefficient etc.
