This project will result in the construction of an automated system for measuring elastic constants and sound velocities in minerals at high temperatures up to 1800 K. The design and construction of the apparatus will be carried out in the Mineral Physics Laboratory of the Institute of Geophysics and Planetary Physics at UCLA. The importance of the measurements that will be made possible by the equipment is tied to fact that geophysical models of the structure of the Earth's interior are partly based on estimates of the velocity of propagation of sound waves at in situ temperatures. The measurement of sound velocities with the new instrumentation will be carried out on the class of minerals considered likely to be present in the mantle and will play an important role in testing and refining models of the interior.

该项目将建造一个在1800K以下的高温下测量矿物中弹性常数和声速的自动化系统。该仪器的设计和建造将在加州大学洛杉矶分校地球物理和行星物理研究所的矿物物理实验室进行。该设备将使测量成为可能的重要性与这样一个事实有关，即地球内部结构的地球物理模型在一定程度上是基于对就地温度下声波传播速度的估计。使用新仪器测量声速将在被认为可能存在于地幔中的矿物类别上进行，并将在测试和改进内部模型方面发挥重要作用。
