Abstract: In this talk we present two fully discrete time-marching schemes including the first order  and the second order schemes for the Cahn-Hilliard equation. The proposed method is based on an improved ``Invariant Energy Quadratization'' method. Here are two distinct features: (i) the two schemes  are linear and  energy stable for the original energy; (ii) the well-posedness and energy stability of the discrete problems are proven. Extensive numerical experiments  are carried out to verify the convergence, the robustness and the energy stability of such  schemes.
