Stars of the first magnitude are the brightest. 第一等级的星是最明亮的。
In two-valued predicate logic a class of special interpretations of first language with nonempty finite domains is introduced. 摘要在二值谓词逻辑中引入了一阶语言的一类特殊解释，该类解释中的解释域取为非空有限集。
Through the intensional interpretation, first-order language gets more close to the semantics of natural language, and is truly neutral to all kinds of subject matter. 比之于外延语义的解释，内涵语义的解释使一阶语言更接近于自然语言的语义，而且也使一阶逻辑对各种题材真正保持了逻辑的中立性。
