| Abstract: | The theory,technology and results of measuring sound velocity of Jilin aerolite at high pressure by using radiometry and using transparent material as the window in the pressure range from 42.2 to 113.2GPa are described in this paper.According to the relation between sound velocity of Jilin aerolite and shock pressure the phase transition of Jilin aerolite near 65GPa can be determined. |
