摘　　要：本文主要介绍Chomsky《语段推导》中所建立的特征操作体系,以及如何完成特征一致(Agree)操作的全过程。校验生成式合法性在于演算过程中对词项特征(形式特征)的操作处理,特征的操作以相应词项的特征实现了一致关系(Agree)为最终目的,一致关系(Agree)的实现以不可解读特征的赋值并且删除为标志。在完成一致操作(Agree)的过程中,所有操作必须满足“最简连接条件”(MLC)、遵守“语段不可穿透原则”(PIC)以及符合“匹配最大化”的规则等。The article tries to give an exposition on the feature system and the mechanism of agreement that has been modified and revised in DbP. In the new system, agreement operation is carried out between interpretable features and uninterpretable features. Uninterpretable features must be valued and deleted before the derivation proceeds to LF. However, agreement operation must satisfy MLC (the Minimal Link Condition) , PIC (Phase Impenetrable Condition) and the principle of Maximizing matching effects, etc.
