提出“语义模”的概念并对一元定中短语从定语和中心语语义关系角度进行研究。语义模和“的”字隐现密切关联,其他语言规律也制约“的”字隐现。 The concept of “semantic modulo ” is proposed and the research on the semantic relationship between attributive and central semantic phrases is studied. The semantic model and “” characters are closely related, other language rules also restrict “” characters appear.
