The study mainly focuses on the non-classical words in Dunhuang manuscripts of Tang Dynasty. We built a visualized database which not only showes the process of evolution and variation in detail of the non-classical words, but also illustrates the causes of formation, the principles of variation, the product of evolution in this period, and other relative issues. This paper is divided into four sections. The first section is to introduce some achievements of Dunhuang non-classical words, then explain what will be demonstrated in this paper. In section two we make a statistics about what had happened to Dunhuang non-classical words in three periods of Tang Dynasty. For the sake of clarifying the principle of evolution and variation in non-classical words of Dunhuang manuscripts, microscopic research and macroscopic analysis are operated in the third section. The final section makes a conclusion about the whole study. The target of this paper tries to set up a modeling with clue of time so as to conduct a systemic research at the macro level.
