摘要

本工作通过对γ射线辐解TBP的气相产物分析，得到了体系吸收剂量外推接近零时各气相产物的G值，解释了DBP+MBP酸性产物和气相产物求物料平衡时的差数。还研究了DPSO-TBP体系能量转移动力学，从烃类产物谱中求得的动力学参数与测定酸性产物（DBP+MBP）求得的一致。在此基础上进一步探讨了氢气形成途径：一种可能来源于刺迹（spur）反应，而另一种则为抽氢反应。

Abstract

(1) The actual G values of gas radiolytic products of TBP (saturated with N,2, and air) were obtained when the absorbed dose approaches to zero. The formation mechanism of gas radiolytic products has been discussed.,(2) The energy transfer kinetics of TBP-DPSO system under γ-irradiation has been investigated. The kinetic parameter obtained by determining the G values of acid products is equivalent to that of gas radiolytic products of TBP.,(3) The mechanism of formation of hydrogen under γ-irradiation bas been discussed. It is evident that there are two different pathways of formation if hydrogen exists. One may be molecular process taken place in spur and the other may be hydrogen abstraction reaction initiated by H atom.
