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。
