摘要

IT is very important to measure physical parameters of minerals, rocks, melts and fluids at high pressure and high temperature. The data from these experiments can provide materials for explanation of geophysical observations on large scale, and information of geochemical field. Therefore, we set up measurement methods on elastic wave velocity, electrical conductivity and differential thermal analysis in YJ-3000 ton press fitted with a wedge-type cubic anvil. In the past 10 years, we have upgraded our measurement level and reached the experimental pressure of 10 GPa, temperature of 2 000 deg C by automatizing the temperature and pressure control system of YJ-3000 press and improving the measurement methods. This note reports some achievements of our laboratory by a lot of experimental studies.
