Abstract：
By using the valon model, the electric form factor of the proton in the nucleus G_E^P(Q²), and π decay constant f_π are discussed. After combining the (e,e') reaction on the ⁵⁶Fe near the quasielestic peak, it is found that G_E^P(Q²) and f_π are influnced by the nuclear medium and their modifications result from increased hadron size as the distortions of structure functions (EMC effect) do.
