一种高温高压下防止试块爆炸的新技术

301||A NEW TECHNIQUE TO PREVENT SPECIMENS FROM EXPLOSION AT HIGH TEMPERATURE AND HIGH PRESSURE

本文采用在传压介质（如叶蜡石等）棱边附近埋置加强筋的方法，有效地防止了样品从传压介质中被挤压冲出来，从而提高了实验的成功率。对此方法的防爆原理，及加入加强筋后高压腔中的温度、压力等进行了讨论，实验在立方体高温高压装置上完成，压力测至6．0GPa。

This paper introduces an explosion-proof technique for the experiments at high tempera-ture and high pressure in the cubic-type ultrahigh pressure apparatus. Reinforcement bars areplanted near the edges of the pressure trans ferting media (here the pyrophylIite cube) can effec-tively prevent melting sample from blowing out of the high pressure cell. Use of the technique mayraise the experimental success rate. The mechanism and the variati0n of temperature and pressurein the cell after the reinforcement bars are planted are discussed as well. The experiments weredone up to 6. 0 GPa and 1 740℃.
