摘要

摘要: 本文报导了利用10 MHz超声脉冲回波重合法，测量非晶碳的声速及其在1 GPa压力以内的变化规律，得到非晶碳的二阶弹性常数（SOEC）、三阶弹性常数（TOCE）及组合的四阶弹性常数（FOEC），从而进一步计算和研究非晶碳的Gruneisen常数，德拜温度D，比热以及在高压下的状态变化。

Abstract: By using the pules echo ultrasonic technique with 10 MHz, the ultrasonic velocities of the amorphous carbon and their pressure dependence have been measured in the pressure up to 1 GPa. We have calculated its second-, third- and combinations of forth-order elastic constants, and have researched its Gruneisen constant, Debye temperature, specific heat and state change under high pressure.
