A diamond-anvil, high-pressure apparatus was used to extend the upper pressure limit of static laboratory experiments. Shifts of the R(1) strong fluorescent line of ruby were observed that correspond to static pressures of 0.21 to 0.55 terapascal (2.1 to 5.5 megabars) at 25 degrees C. Sensitive spectroscopic techniques in the pressure range 0.15 to 0.28 terapascal were used to observe ruby and diamond fluorescence separately; these two fluorescent emissions overlap strongly at high pressures. At pressures greater than approximately 0.28 terapascal, the diamond fluorescence diminished and the ruby fluorescence reappeared strongly. Pressure was determined by extrapolation of the calibrated shift of the ruby R(1) line.
采用钻石压砧高压设备将静态实验室实验的上限压力扩展到 0.21 到 0.55 太帕斯卡（2.1 到 5.5 兆巴），在 25°C 时观察到红宝石 R(1)强荧光线的位移。在 0.15 到 0.28 太帕斯卡的压力范围内，使用灵敏的光谱技术分别观察到红宝石和钻石的荧光；在高压下，这两种荧光发射强烈重叠。在大于约 0.28 太帕斯卡的压力下，钻石荧光减弱，红宝石荧光强烈再现。压力通过红宝石 R(1)线校准位移的外推来确定。
