9418685 Getting The proposed research will provide high pressure petrologists with a method of absolute pressure-temperature calibration that can be utilized in laboratories throughout the research community. The method is based on the accurate determination of several intersecting equilibrium boundaries in a gas piston cylinder apparatus. Apparatus in other laboratories are calibrated, in both absolute temperature and pressure, by referring equilibrium observations in those devices to the PIs' accurately determined boundaries. The proposed research will determine phase equilibria with an absolute pressure and temperature accuracy of 1% at pressures between ~1.5 and 3 GPa and between 700 and 1600 (K.

9418685 拟议的研究将为高压岩石学家提供一种绝对压力-温度校准方法，可用于整个研究界的实验室。 该方法是基于精确确定的几个相交的平衡边界的气体活塞缸装置。 其他实验室的仪器，在绝对温度和压力方面，都是通过参考这些仪器中的平衡观测值与PI精确确定的边界进行校准的。 拟议的研究将确定相平衡，绝对压力和温度精度为1%，压力在~1.5和3 GPa之间，压力在700和1600（K）之间。
