空洞攻击：本文根据正电子吸附的中性物质腺嘌呤（A）、胸腺嘧啶（T）、鸟嘌呤（G）、胞嘧啶（C）及其Watson-Crick碱基对（AT和GC）的计算结果，提出了一个核碱基分子及其碱基对被正电子单电子氧化的理论模型。结果表明，正电子与中性分离核酸碱基分子的结合是碱基选择性的。
Hole attack: A theoretical one-electron oxidation of nucleic base molecules and their pairs by positron is proposed, based on the calculations for positron-attached neutral forms of species, adenine (A), thymine (T), guanine (G), cytosine (C), and their Watson-Crick base pairs (AT and GC). The results reveal that binding of a positron to neutral isolated nucleic base molecules is base-selective.
