SIMULTANEOUS MEASURING METHOD FOR TEMPERATURE AND PRESSURE BY X-RAY ABSORPTION SPECTROSCOPY

摘要

PROBLEM TO BE SOLVED: To simultaneously measure temperature and pressure in a high temperature high pressure generator without using a thermocouple by measuring a fine structure of an edge absorption spectrum by an X-ray absorption spectroscopy of a standard material. SOLUTION: The method simultaneously determines temperature and pressure in the device from the period and amplitude of fine structure of the edge absorption spectrum by the X-ray absorption spectroscopy of the standard material put on the high temperature high pressure device.
