摘 要:We consider certain one-dimensional reaction-diffusion models for two chemical substances with concentrations A(the reducing agent) and B(the coupler).The reducing agent diffuses and combines with the *** the diffusion coefficient D(x) and the reaction rate k are *** that final time(t=T) measurements on A(x,T) and B(x,T) are given,the problem is therefore to identify D(x) and k.A homotopy method is proposed to allow us to identify these coefficients and some numerical experiments are made.
