形式语法对语序的解释能力来自于其内在结构上的不对称。文章证明,把这种结构性的非对称应用于连动式中的语序-时序对应现象,充其量只能处理小部分的语料。因此自然语言中至少应该包含两种本质不同但共存的语序机制:源于非对称结构的先后顺序和语序与数个被描写事件的时间顺序的直接对应。 Formal grammar to explain the order of the ability to come from its inherent structural asymmetry. The article proves that the application of this structural asymmetry to the sequential-temporal correspondence in linked systems can only deal with a small part of corpus at best. Therefore, natural language should include at least two kinds of essential but coexistence of the word order mechanism: the order and sequence of words originating from the asymmetric structure correspond directly with the chronological order of several described events.
