  In this paper, we define the L{\phi}-Lipschitz norm and L{\phi}-BMO norm of
differential forms using Young functions, and prove the comparison theorems for
the homotopy operator T on differential forms with L{\phi}-Lipschitz and
L{\phi}-BMO norms. As applications, we give the L{\phi}-BMO norm estimate for
conjugate A-harmonic tensors and the weighted L{\phi}-Lipschitz norm estimate
for the homotopy operator T.
