| 摘 要： | 计算了N，N，N’，N’-四丁基-3-氧-戊二酰胺（N，N，N’，N’-tetrabutyl-3-oxa-pentanediamide，TBOPDA）中各个原子的电荷分布，根据电荷分布情况讨论了TBOPDA中有关化学键的相对稳定性和可能断裂几率，认为TBOPDA中化学键的辐照稳定程度为C-O〈C-H〈C-N〈C-C。理论推测的结果与相关辐解产物的产额顺序基本一致。

| Abstract: | The partial electron of atoms in N,N,N,,N,-tetrabutyl-3-oxa-pentanediamide (TBOPDA) was calcu- lated with MM+ codes. The stability and cleavability of different single-bonds were discussed, with the radiation sta- bility being C-O < C-< C-N < C-C. The calculation results were confirmed experimentally by G values of radioly- sis products of TBOPDA samples, which were measured by solid phase micro-extraction and gas chromatog- raphy. |
