Study Of The Application Of The Buoyancy Principle In Ancient China

Buoyancy principles as an important principle of physics, and life in many areas of industry and agriculture are widely used. Also known as Archimedes principle of buoyancy. However, in ancient China, both for the principle of buoyancy of the times that interpretation, or the principle of buoyancy in the various fields of application, are beyond the Archimedes. In the splendid ancient Chinese civilization, science and technology achievements, the construction of large ships, the construction of water conservancy facilities, small enough to make the shaft, testing salt water density, both on a deep understanding of the principle of buoyancy and very careful use. In ancient China, the application of the principle of buoyancy, penetration not only in agriculture and handicraft industry in all aspects of social life, and in many areas of application of the principle of buoyancy for some have played a key role. For the ancient Chinese principles of the previous application of buoyancy, scattered in a field of certain aspects or discourse. And specifically the principle of buoyancy material as the focal point for the assembly and analysis are rare.The buoyancy principle for the central axis, the collection of ancient Chinese principle of buoyancy applications on all aspects of the historical data so concentrated and analyzed, summed up the buoyancy principle for the application of general laws and principles of the content and buoyancy of ancient Chinese science and technology, especially applied technology the relationship between the development process, and a summary and analysis of data combined to discuss the application of the principle of buoyancy caused by ancient Chinese thought and inspiration, and some details in the article put forward some new views on the writing of this article want to achieve purposes.Article introduction, the first time in accordance with the principle of buoyancy in ancient China to briefly discusses the application of focus, and describes results of previous studies.The second part introduces the basic principles of buoyancy statements and concepts, and well-known principle of Archimedes and buoyancy, buoyancy found a close relationship.The third part introduces the principle of buoyancy in ancient China made the first record of the works "Mexican Classics" in the description of the principle of buoyancy, and Archimedes discovered buoyancy principle with the times compared.The fourth part, according to different application areas, the principle of buoyancy on the application of ancient Chinese historical materials to be classified and analyzed. First, handicrafts, wooden, bamboo utensils application of the principle of buoyancy, but also is light craft on the application of the principle of buoyancy. Followed by bronze casting metal casting, especially the application of the principle of buoyancy, or a heavy craft on the principle of application of the principle of buoyancy. Then the shipbuilding, bridges, construction of water conservancy facilities and other large construction projects in the application of the principle of buoyancy. Finally, the collection of other aspects of social life the application of the principle of buoyancy. In the bronze casting, made of "Kao Gong Ji" is the amount of Li's article in the "Criteria" of the process of personal opinion.The fifth part, the initial failure to explore why the principle of buoyancy in the development of China sublimation of buoyancy, the experience from the applications level, rise to the field of science has a strict quantitative analysis of logic.
