用定容法研究了５５０～７８０℃范围内钛的吸氢和放氢动力学。吸氢和放氢的激活能分别为７８．６和１０５．６ｋＪ／ｍｏｌ。吸氢由相界面过程控制，而氢原子穿过表面氧化膜是放氢速率控制步骤。
The kinetics of hydrogen absorption and desorption of titanium in the range of 550 ~ 780 ℃ was studied by constant volume method. The activation energies of hydrogen absorption and desorption were 78.6 and 105.6 kJ / mol, respectively. Hydrogen absorption by the phase interface process control, and hydrogen atoms through the surface oxide film is the hydrogen release rate control step.
