Experimental Study on Measuring Sound Velocities of Jilin Aerolite at High Pressure
-
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42.2~113.2 GPa，得到了吉林陨石的高压声速随冲击压力的变化关系，并由此判断出吉林陨石在约65 GPa时发生相变。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 113.2 GPa 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 65 GPa can be determined.
