将样品装入一个长3.81 cm、直径1.27 cm的装有液体的钢胶囊中，再将其放入通常用作2000吨六面体压机样品室的叶蜡石立方体中。当以正常方式施加压力时，它通过异戊烷和戊烷的1：1混合物传递到封闭的样品。利用六个电引线到样品区域的成功测量已经完成。一个锰铜压力计到60 kbar的演示和用于研究以前未观察到的时间依赖性的压力变化归因于叶蜡石流在固体介质装置。
A sample is enclosed in a liquid‐containing steel capsule 3.81 cm in length and 1.27 cm in diameter, which in turn is placed in the pyrophyllite cube normally used as the sample chamber of a 2000‐ton hexahedral press. When pressure is applied in the normal manner, it is transmitted to the enclosed sample by a 1:1 mixture of isopentane and pentane. Successful measurements utilizing six electrical leads into the sample region have been made. A manganin gauge to 60 kbar is demonstrated and used to study previously unobserved time‐dependent pressure variations attributed to the pyrophyllite flow in the solid‐media apparatus.
