压力对物理性质的影响对于理解高关联电子系统是非常重要的，在高关联电子系统中已经观察到了压力诱导的吸引现象，如超导和磁有序的非费米液体。到目前为止，许多科学家已经为各种用途开发了大量的高压仪器。本文介绍了一种用于高达8 Gpa高压下精密电输运测量的小型“手掌立方砧式高压仪”。这种压力计最突出的特点是它的紧凑性。它使我们能够测量不同温度下的电阻率、磁阻和霍尔系数的绝对值。介绍了我们研制的手掌立方高压装置的详细情况，并讨论了一些室温下的中子实验结果。
Effects of pressure on the physical properties are very important for understanding highly correlated electron systems, in which pressure-induced attractive phenomena such as superconductivity and magnetically ordered non-Fermi liquid have been observed. Up to now, many scientists have developed a lot of high pressure apparatus for each purpose. In this paper, we present the very small “palm cubic-anvil high-pressure apparatus” for precise electric transport measurements under high pressure up to 8 GPa. The most outstanding characteristic of this pressure cell is its compactness. This cell enables us to measure absolute values of electrical resistivity, magneto-resistance and Hall coefficient at various temperatures. The details of our palm cubic high-pressure apparatus are introduced, and some neutron experimental results at room temperature are discussed.
