摘　　要：应用反应速率分析方法,通过测定钛在恒容系统内和823～1 023 K范围氚化反应的P-t曲线,计算了钛氚化反应的速率常数,得到钛氚化反应的表观活化能为(155.5±3.2)kJ/mol.通过与文献比较,钛氚化反应的表观活化能明显高于钛氢化和钛氘化的表观活化能.P-t curves of titanium tritiation a investigated at the 823～1 023 K by using the method of the reaction rate analysis in a constant volume system. The rate constants of titanium-tritium reaction are determined and the activation energy obtained by this analysis is （155.5±3.2） kJ/mol. The activation energy of titanium-tritium is obviously higher than that of titanium hydrogenation and deuteration from comparing with the reported data.
