In chapter one of the paper,we have given the four steps of theoretical research for chapter two,we ma de a historical review to mechancis laws(dynamics and ics) that controlled motion of chapter three and five,from physical modelling point of view,we studied respectively hydrodynamics in Galileo-Newton absolute space-time and Einstein relati vistic space- chapter four,from mathematical methods point of view,we made a brief introduction to three perspectives ,which were mathematical structure of PDE of hydrodynamics and the solution properties of PDE of hydrodynamics, statistical fluid dynamics ,methods of dynamical systems and the last chapter(chapter six)
