摘要：

A mathematical model is proposed to describe extraction from a semi-infinite body with pores of two types, namely, large pores extending to the surface and small pores communicating with the large pores. The effective transfer coefficients in the two types of pores are assumed to be different. By the fractional differentiation method, the time dependence of the extractant flux through the body surface is described. The theoretical results are compared with experimental data.
