In chapter 4,taking the CCSD results as references,the performances of five DFT(BHandHLYP,MPWB1K,B3LYP,B3PW91 and SVWN) and two WFT(HF and MP2) methods for describing relative conformer energies,vertical electron detachment energies,deprotonation energies,and proton affinities of 22 amino acids were determined.

第4章中以高精度的耦合簇方法的计算结果为基准，测试了五种密度泛函方法(BHandHLYP，MPWB1K，B3LYP，B3PW91和SVWN)和两种波函方法(HF和MP2)对描述22种氨基酸体系的构型相对能量，垂直电离能，质子化和去质子化能这四种能量性质的能力。

质子治疗系统主要的设备是射线源发生器，有回旋加速器和同步加速器两种。

The results showed that the preoxidation of PPESK was a free radicals reaction,which was initiated by the decomposition of proton in aromatic ring and sulfone functional group and the removal of H_2O and SO_2.When the preoxidation temperature was above 460℃,the radical reaction was initiated by the decomposition of ketone functional group and the removal of CO_2.At last,the three-demensional cross-linking structure containing polyaromatic ether and biphenyl was formed.

研究表明，PPESK的预氧化过程是一个自由基反应过程，始终伴随着芳香环质子和砜基官能团的脱除引发的自由基交联反应，脱出H_2O与SO_2；当预氧化温度超过460℃后，随着反应的进行，由羰基官能团分解引发的自由基交联反应开始发生，脱出CO_2，并最终形成了含有大量聚芳醚和联苯结构的稳定的三维空间网状结构，进而完成PPESK由热塑性材料向热固性材料的转化。
