藏語語法體系中,不管是詞法、句法,還是語義層面,其格標記不變,但其功能隨著所標記語法的不同層面而延伸變化,這種變化正是虛詞規則所觀照的。在配價過程中,藏語有其獨特的形態標記,它通過對動詞配價和從屬關係的描寫,可以使句子結構更加明朗,語義指向更為清晰,因此,配價語法給藏語句法和語義結構描寫提供了一種操作性很強的方法。

In Tibetan grammar,there is no change of case markers at lexical,syntactic and semantic levels,while their functions will extend and change at different levels of case grammar. The changes follow the rules of function words. In the process of valence,Tibetan language has its unique morphological markers,which can make the sentence structure and semantic orientation clear by describing verbal valence and subordinate relations. In this way,valence grammar has provided a very operational method for the description of Tibetan syntactic and semantic structures.
