Abstract: In this paper, the Petri net models are established for right linear grammar, expression grammar and property tree formal grammar. The structure algorithms of these models are given and the properties of models are discussed. It is pointed to gene rate language process based on Petri net models by examples. So it is shown that the models are not only intuitional but also dynamic.

Key words: property tree formal grammar, expression grammar, Petri net, right linear grammar, construction
