【Abstract】 This paper concerns the solution of diffusion equations ut-Duxx=0 with the initial value u（0，x）=f using Yosidas semi-groups method.We give the concrete solution for this kind of initial value problems for second-order parabolic equations.
【key words】Diffusion equation，semi-groups of bounded linear operators，norm space.
