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
