[求助] 翻译

我是一个本科生,写毕业论文,摘要不会翻译,麻烦那位虫友帮忙翻译?内容如下
利用密度泛函法对九种腺嘌呤-胸腺嘧啶碱基对(A-T)以及它们的相应的阳离子在wb97xd/6-311++g(d, p)基组水平下进行优化和频率分析,结果显示对中性复合物和阳离子复合物结构的几何参数得到中性复合物[A(N25)-T(15)]7转化为[A(N25)-T(15)] +7结构变化最大。用密度泛函uwb97xd/6-311++g(d, p)的方法进行NBO计算,NBO分析显示弱相互作用是通过成键轨道与反键轨道间的电子转移来实现。用基组aug-cc-pvdz计算其各复合体系的单点能,结合相对能量、电离势、结合能分析得到阳离子[A(N28)-T(H12)]+3复合物的结构最为稳定。

In this paper, we(or I) use density functional method to optimize and analyse frequencies of nine kinds of adenine-thymine base pairs (A-T) and their corresponding cations with wb97xd method and 6-311++g (D, P) basis set. We(or I) get data of the structural geometric parameters of the neutral complexes and the cationic complex, which indicates that the structure of neutral complex [A (N25) -T (15)]7 converted into [A (N25) -T (15)] +7 has the biggest change.By using  uwb97xd  method and 6-311++g (D, P) base set for NBO calculation, NBO analysis shows that the weak interaction is acheieved by means of electron transfer between the bonding orbital and antibonding orbital .The aug-cc-pVDZ basis set is applied to calculate the single point energy of different composites system, combined with the relative energy, ionization potential, the binding energy.The results show that the cationic [A (N28) -T (H12)]+3 complex has the most stable structure.
