不同温压条件下弹性波在岩石中传播速度的实验研究

EXPERIMENT STUDY ABOUT ELASTIC WAVE VELOCITIES IN ROCKS UNDER DIFFERENT PRESSURE AND TEMPERATURE

对以岩浆岩为主的岩石类型进行了不同温压条件下弹性波传播速度的实验研究，结果表明：（１）岩石的物质组成是决定弹性波传播速度的主要因素。以岩浆岩为例，由酸性到基性波速呈增加趋势；（２）岩石中弹性波的传播速度随环境条件改变而变化。一般说来，随温压条件的升高而升高。

During study on Manzhouli-Suifenhe Global Geoscience Transect(GGT), P.R.China,the authors have done a series of experiments about elastic wave velocities in rocks under various pressure and temperature. The results show that:(1) the composition of rock is a major role in transimitting elastic wave velocity in rocks, for example, the velocity tends. to increase from the acid rock to the basic ;(2) Elastic wave velocities in rocks vary with the pressure and temperature, usually increasing with the increase of pressure and temperature.
