摘要
叙述了以透明材料作窗口,用辐射法测量吉林陨石的高压声速的原理、实验技术和实验结果,实验压力范围为42.2~113.2GPa,得到了吉林陨石的高压声速随冲击压力的变化关系。
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.
