The Primary Study On Physical Phenomen In Dunhuang Materials

The Dunhuang literature and Dunhuang wall-painting are a huge treasure trove of information,including many scientific and technological information.We will study with Dunhuang studies physics knowledge,the combination of physics perspective to study Dunhuang studies related issues,will be related to the physical phenomenon in Dunhuang literature and frescos part information on science and technology,probes into the problems of the following aspects:With regard to the mechanical phenomena,the application of the frame of reference is analyzed,and the application of the principle of leverage and the principle of buoyancy is discussed in this paper.On the phenomena of optics and t hermology,the wonderful optical phenomena recorded in Dunhuang literature are discussed,and the phenomenon of the plane mirror image in Dunhuang frescoes is also analyzed.The thermal phenomenon is based on the "wine map" in Dunhuang fresco,and explains it from the thermal perspective.In terms of time and space,there are 13 kinds of time units recorded in Dunhuang literature,including 10 traditional time units and three buddhist time units.It is found that the Dunhuang people also have a sense of space.Common in Dunhuang literature is discussed in the end of ten kinds of length and the conversion relation between them,the analysis tubo length unit to 40 cm the length of the "arrow",another name is "elbow".Based on the study of the physical phenome na of the Dunhuang literature and wall-painting,let us to a deeper understanding of value in the history of C hinese,an enriched the content of ancient C hinese history research,but also can understand the Dunhuang people understanding of physical phenome na,from the side to reflect the development level of science and technology in the tang dynasty.
