It is pointed out that crystals are discrete but not continuous materials. Hence the rotation R in decomposition F = RU and spin W in F F-1 are not correct. Err
From the Navier-Stokes equations, the integral expressions of the free-surface elevation and the velocity field in ship waves of a moving waterborne body are ob
A method that series perturbations approximate solutions to N-S equations with boundary conditions was discussed and adopted. Then the method was proved in whic
