A natural boundary reduction initiated and developed by Feng Kang and Yu Dehao [1～4] is applied to solve the exterior initial boundary value problem of 2D parabolic equation, and a new coupled method of the natural boundary element method (NBEM) and finite element method (FEM) is suggested.

Finally,the iteract ion method of BEM mentioned above is compared with the coupled method of BEM that was pesented before then by authors.

In this paper, the coupling method is discussed of nature boundary element and finite element method for solving 2D exterior harmonic problem with elliptic artificial boundary, existence and uniqueness are studied of the solution of variational problem with coupling method and error estimates is analyzed about the approximate solution.

To settle the disadvantages of activated carbon separately prepared by physical activation and chemical activation processes, a novel coupling approach of physical and chemical activations was postulated.
