摘　　要：A transmission-reflection-combined new method is presented for measuring elastic velocities of rocks and minerals at elevated temperature and pressure,which resolves the problems of gradients of temperature and pressure existing in original sample assembly with a pyrophyllite cube.At room temperature and pressure up to 3 GPa,single-crystal quartz and eclogite were used to provide samples under test,respectively.The results of this work agree with the previous measurements very well within the error range.By the use of this new technique,more precise and reasonable data of elastic properties of rocks and minerals at elevated temperature and pressure can be achieved.
