A Brief Introduction to Screwy Surfaces Equation and Box Transformation Coordinate System --Understanding a new type mathematic train of thoughts and method Cao Yupin1 , Chen Zhanjie2 (No.1 Geological Exploration Institute of Henan Bureau of Geology and Minerals Exploration, Nayang, Henan; 2. Ministry of Land and Resources, Peking 100812) Abstract: Box transformation coordinate system was a new type coordinate system changing homonymy coordinate unit of conventional rectangular coordinate system from completely equal into completely variable, not only realized accurate expression of various screwy surfaces equation, but also basically solved the problems of various screwy surfaces, non-linear uneven dynamic limited space, function and image dynamic corresponding. Its promotion would cause major breakthrough or reform of modern mathematic and its related subjects. Keywords: screwy surfaces; positive box body; box transformation coordinate system; variable coefficient; variable function Introduction: In real life, various screwy surfaces exist everywhere, but it is difficult for current coordinate systems to have accurate expression and relevant accurate operations. Therefore, this author tried a non-traditional box transformation coordinate system, box transformation function and relevant variable operation, and furthermore extended it into a complete set of variable method. Although quite hoarse, this set of method fundamentally revealed certain universal mathematic rules. In order to facilitate exchange and save space, this author briefly described a part of its train of thoughts and method below with the purpose to offer a few commonplace remarks by way of introduction so that others may come up with valuable opinions. This paper focused on a brief introduction to screwy surfaces equation and box transformation coordinate system, the rest could be seen from the book of “Elementary Study on CS Variate Method ”, out of which, due to the descriptions frequently ex
