为了在不牺牲样品体积的前提下扩大大容量六面顶压机的压力范围，研制了一种顶砧-预成型垫片系统。在室温下使用Bi、Tl和Ba中的转变校准该系统的样品室压力与压力负载的关系。对于类似的样品体积（直径为8-11 mm，长度为8 mm），砧座-预成型垫圈系统可以产生高达约8.5 GPa的压力，显著高于6 GPa，这通常是常规砧座-垫圈系统的最大压力。本文详细介绍了砧座-预成型垫片系统的优化设计。
An anvil-preformed gasket system has been developed to extend the pressure range for the widely used large volume cubic press without sacrificing the sample volume. The relationship of the sample chamber pressure versus press load for this system was calibrated at room temperature using transitions in Bi, Tl, and Ba. With similar sample volumes (8-11 mm in diameter and 8 mm in length), the anvil-preformed gasket system can generate pressures up to about 8.5 GPa, significantly higher than 6 GPa, which was generally the maximum pressure for the conventional anvil-gasket system. The details on the optimized design for the anvil-preformed gasket system are given in this note.
