Keywords:

problems convective diffusion,
volumetric chemical reaction.
Classes of the differential equations with small parametre of the elliptic type, containing special points of type of a saddle in the limiting equation are investigated. Asymptotic expansion of the solutions of boundary value problems convective diffusions about a particle are constructed. Theorems of existence are proved and asymptotic expansion of the solutions for some classes of the quasilinear ordinary differential equations arising in problems convective diffusion taking into account volumetric chemical reaction are constructed.
