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.

The study of the non-classical words in Dunhuang Manuscripts mainly focuses on the process of the analysis in the whole words. In the meantime, the component analysis should be another way to describe the influences of their variation to the formation, development and changing of non-classical words. In this paper, there are five sections to demonstrate the statistical study. Section one is elementary information about the study of non-classical words in Dunhuang Manuscripts which provides a brief introduction to the audience. The source of materials, the basis and methods of operation, and some particular issues are mentioned in section two. In the third and fourth section, charts and diagrams are used to illustrate the words sample set in relation to component variants, giving an explicit presentation about what changes had happened in the same component, and the relationship between components and their variants. The last section is a conclusion about what we had done in the study and what we need to pay more attention to in the future. The chiefly task of the study is to establish a visualized statistical database of component variations quantity statistics by means of components decomposing and classifying. The conditions of diachronic change and synchronic variation in components of non-classical words in Dunhuang Manuscripts can be shown distinctly. It also makes preparation for further studies on individual word, its evolvement rule and other relative research.
