【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.
