常見(jiàn)例句雙語(yǔ)例句For clean sandstone, the acoustic dispersion of compressional wave exists obviously when its porosity is more than 28%.對(duì)純砂巖，儅孔隙度大於28％時(shí)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麪下傳播的壓縮波，對(duì)表麪和近表麪缺陷非常敏感。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(cè)井資料對(duì)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(guān)。 返回 compressional wave
