我们已经在高压和高温条件下建立了一个基于AC复合阻抗方法的高压和高温条件的电导率测量系统。使用该系统，我们成功地测量了在高达5 GPA的压力下San Carlos橄榄石的电导率。我们解释了激活焓和激活量的物理含义，并为这些数据提供了值，这将是理解橄榄石的传导机制的重要帮助。
We have set up an electrical conductivity measurement system under high-pressure and high-temperature conditions with a multi-anvil high-pressure apparatus based on an AC complex impedance method. With this system, we have successfully measured the electrical conductivity of San Carlos olivine under pressure up to 5 GPa. We explain the physical meaning of the activation enthalpies and activation volumes and give values for these data, which will be a great help for understanding the conduction mechanism for olivine.
