摘要: 采取突然加压的方法，测量在施压过程中产生的温度变化，从而直接决定物质的格留乃森（Grneisen）参数。第一次在固体传压介质中进行该种实验，并在高达3.5 GPa的压力范围内，直接测量了铝的格留乃森参数随压力的变化。

Abstract: Using a quasi-adiabatic method, and measuring the temperature change in the compressive process, we can directly determine the Grneisen parameter in various materials. In the world, only one laboratory had performed such a technique in the high pressure system in which the liquid transmit medium was used. In the present work, we report the results of determination of the Grneisen parameters of Al up to 3.5 GPa. It is the first time to carry out such a measurement in a high pressure system with solid pressure transmission medium.
