对立统一规律是人们认识一切事物的根本原则,可以用来解释国际私法的范围问题。国际私法的方法与国际私权关系的矛盾是从国际私法规范中离析出一对主要矛盾;其中,国际私权关系是该矛盾的主要方面。该矛盾足以解说国际私法规范范围问题。 The law of unity of opposites is the basic principle that people know everything and can be used to explain the scope of private international law. The contradiction between the methods of private international law and those of international private rights is to isolate a pair of major contradictions from the rules of private international law. Among them, the international private rights relations are the main aspects of this contradiction. This contradiction is sufficient to explain the scope of the norms of private international law.
