        1.Viscosity and internal friction of fluidFluid is flowable. Even a very small shearing force will deform a fluid body at restwhile fluid can resist deformation by shear stress in motion state. The viscosity of afluid is a measure of its resistance to gra......（本文共 9215 字, 19 張圖）     [閱讀本文] >>
