Force per unit area measurements made in the megabar pressure cell, independently of other pressure calibration systems, are consistent with the ruby R1 scale of Mao, Bell, Shaner, and Steinberg and its extrapolation to 1.4 Mbar. Physical analysis of diamond anvils removed after experiments to maximum pressures of 1.3-1.7 Mbar suggests that the nitrogen platelet concentration may be related to the strength of the diamonds. The pressure face of one of the diamonds from the 1.7-Mbar experiment was deformed plastically by a macroscopic amount.
在兆巴压力室中进行的单位面积力测量，独立于其他压力校准系统，与毛、贝尔、沙纳和斯坦伯格的红宝石R1标度及其外推至1.4兆巴的结果一致。对在1.3 - 1.7兆巴最大压力实验后取出的金刚石砧座进行的物理分析表明，氮片晶浓度可能与金刚石的强度有关。来自1.7兆巴实验的其中一颗金刚石的压力面发生了宏观塑性变形。
