A mechanical model of skating motion was founded, and its solution was obtained by using the Routh's equations in nonholonomic dynamics. The two kinds of co
By tusing Fourier transformation the boundary problem of periodical interfacial cracks in anisotropic elastoplas tic bimaterial was transformed into a set of du
The fluid fluctuating velocity equations which include the term of cylinder particleswere established. The turbulent intensity and Reynolds stress of fluid were
A nonlinear degenerate parabolic equation with nonlocal source was considered.It was shown that under certain assumptions the solution of the equation blows up
