摘　　要：中心优选论COT方案是中心论CT和优选论OT的组合,但沿袭了语篇的首句主题不明确、回指的先行词在前一句中以及句子只有一个主题等观点。由于实际情况是语篇的首句起着建立和引入主题的作用,回指的先行词不一定就在前一句中,句子中可以出现突显程度仅次于主题的语篇实体副主题,因此本文对COT的限制序列进行了局部调整。这种调整仅是示范性质的假设,主要目的是阐述语篇回指解析形式化方案的利弊以及有关理论与语料的辩证关系。As a combination of CT and OT, COT still retains the CT stance that the first sentence in discourse contains no tangible topic and the antecedent for the anaphor must exist in the previous sentence, etc. As this runs counter to actuality, this paper provides some local adjustments of the COT optimality evaluator and comments on this formal approach to discoursal anaphora and its dialectical relationships with pertinent data covered by the theory.
