acoustic wave velocity 中文意思是什麼

acoustic wave velocity 解釋
聲波速度
  • acoustic : adj. 1. 聽覺的；聲學的。2. 助聽的；傳音的。3. 原聲的，不經過電子設備傳聲的。adv. -tically 在聽覺上；在聲學上。
  • wave : n 〈美海軍〉女志願軍人〈見 WAVES 條〉。n 1 波浪；碎浪； 〈the wave（s）〉 〈詩〉海。2 波動；波狀...
  • velocity : n. 1. 迅速；快速。2. 速度，速率。3. 周轉率。
  1. The following results were found, i. e., the water ratio affects obviously the acoustic wave velocity of rock sample ; the wave velocity is higher in saturated rock samples than in unsaturated ones ; and it decreases gradually with the strain of samples during uniaxial compression ; and also with the lengthening holding time at 160 ; when heating the samples the acoustic wave velocity increases slightly in initial stage and comes to the peak value at 60, then decreases gradually with increasing temperature ; meantime, there is a certain temperature effect on rock samples size

    實驗發現含水率對波速影響比較大，飽和巖樣的聲波傳播速度高於不飽和巖樣的聲波傳播速度；人工預制裂紋對聲波傳播速度影響不大；單軸壓縮條件下，聲波傳播速度隨應變增加逐漸降低；在同一溫度（ 160 ）下，波速隨保溫時間的增加而逐漸降低；在對巖樣逐漸加熱情況下，初始加熱階段波速略有升高，當溫度達到60時，巖樣波速達到峰值，之後隨著溫度繼續升高其波速逐漸下降；波速隨溫度變化具有一定的尺寸效應。
