| 摘 要： | Variations in elastic wave velocity, low-frequency internal friction and acous-tic emission in granite were experimentally studied as a function of temperature.It is found that the wave velocity and Young‘s modulus tend to decrease with temperature.In association with the α-β transition of quartz a sharp internal friction peak can be recognized accompanied by a drastic drop in wave velocity and modulus and by a second peak of acoustic emission rate.

| Abstract: | Variations in elastic wave velocity, low-frequency internal friction and acoustic emission in granite were experimentally studied as a function of temperature. It is found that the wave velocity and Young’s modulus tend to decrease with temperature. In association with theα — β transition of quartz a sharp internal friction peak can be recognized accompanied by a drastic drop in wave velocity and modulus and by a second peak of acoustic emission rate. |
