%X Boundary conditions constructed by two typical geometrical config- urations related to the manufacturing methods of bronze process and tin-rich Nb tube method have been considered in a diffusion model in which the diffusion of Sn in CuSn matrix plays a major role is assumed. The dependence of thickness of Nb_3Sn layer on reaction time has been derived. It is shown that the growth rate of Nb_3Sn relates to the configuration of the superconductor, the geometrical parameters of Nb filaments and CuSn matrix. The theory are qualitatively consistent with the experimental results.
