Understanding of the continuum hypothesis in macroscopic mechanics:Macroscopic mechanics (such as fluid mechanics, elasto-plastic mechanics, etc.) are the objects of a large number of molecules, at this time each set constitutes a small micro-body, the whole object is made up of the countless small micro-bodies continuously without gaps in the composition. Because we only need to pay attention to the nature of the objects on each set, such as density, velocity, stress, deformation, etc., do not
