Singular Perturbation Boundary Layer and Inner Layer Theory (Chinese Edition)

It mainly introduces the basic knowledge and basic principle of separation science and common separation methods. There are 9 chapters in the book including preface, precipitation separation, liquid-liquid extraction separation, ion-exchange separation, ordinary differential equation, initial value of functional differential equation and partial differential equation, boundary value problem, initial layer, boundary layer and inner layer phenomenon. It uses methods like stretched variable, matching principle, multi-scale method to construct formal asymptotic solution. And by the theories like extremum principle, energy integral, a priori estimate, upper and lower solutions, fixed point principle to prove the consistent effectiveness of relevant asymptotic solution.
