摘要:Abstract(#br)We establish some reverse inequalities. We give applications to nonlinear elliptic boundary value problems containing a parameter λ which have two branches of solutions u λ (λ≥0) and U λ (λ>0) of which the first is continuous at the origin and the second in...

摘要:Abstract(#br)Although the unique liquid behavior renders structured corrugation SiC foam packing (SCFP-SiC) a great alternative in distillation, the separation efficiency depends heavily on capacity and liquid property. The aim of this work is to discuss the change of flow patter...
