compressional wave

基本解釋

For clean sandstone, the acoustic dispersion of compressional wave exists obviously when its porosity is more than 28%.
對純砂巖，當孔隙度大于28％時存在明顯縱波聲頻散。
Creeping wave is a type of compressional wave, which propagates below the surface and is sensitive to surface and near-surface defects.
爬波是一種在材料的表面下傳播的壓縮波，對表面和近表面缺陷非常敏感。
By comparison with other logging data, the amplitude of Stoneley wave and the ratio of Stoneley wave amplitude to compressional wave amplitude are related to formation permeability.
將它們與其它測井資料對比，發(fā)現(xiàn)斯通利波的幅度及其與縱波幅度的比值與地層的滲透性有關。
