Ruby crystals were subjected to a static pressure greater than 1 megabar in a diamond-windowed pressure cell. The pressure was monitored continuously by observing the spectral shift of the sharp fluorescent R(1) ruby line excited with a cadmium-helium gas-diffusion laser beam. One megabar appears to be the highest pressure ever reported for a static experiment in which an internal calibration was employed.
在一个带有金刚石窗口的压力室中，对红宝石晶体施加了大于1兆巴的静压力。通过观察由镉 - 氦气体扩散激光束激发的尖锐荧光R(1)红宝石谱线的光谱位移来连续监测压力。1兆巴似乎是有史以来在采用内部校准的静态实验中所报道的最高压力。
