Abstract: The use of optical pyrometer to measure temperature in diamond-anvil ultrahigh pressure device is different from that under normal conditions because the temperature is measured through the optical system of microscope.Therefore,a caribration is recessary for the used optical pyrometer.There exists an interference from miscellaneous light in using the ruby R₁ fluorescence technique to measure the pressure.In this paper,we introduce a method of temperature calibration for optical pyrometer and discuss how to estimate the pressure in the region of interference.

摘要： 在金刚石砧式超高压装置中,测温用的光学高温计的使用和一般使用情况不同。它要通过显微镜的光学系统去进行测量。因此,必须经过标定。在用红宝石荧光法测量压力时,存在着杂光干扰的问题。本文介绍一种标定光学高温计的方法和讨论在杂光干扰区如何估计压力。
