For heat conduction equations and diffusion the solution is created in the beginning for "simplis" case, and then by introduction of any functions the solution of the specific equation with boundary and entry conditions is discovered. The law of a refinement " for vegetative raw material is offered new ". Using a method of explosive solutions the concentration of voltages near a curve imperfection is constructed. The task of interaction of harmonic waves of a torsion with disk-shaped rigid отслоившимся by an imperfection is decided Product Description popup.authors popup.nrat_date 2020-04-03 Close
