  For deuteron electromagnetic form factors,perturbative QCD(pQCD) predicts
that $G^{+}_{00}$ becomes the dominate helicity amplitude and that $G^{+}_{+0}$
and $G^{+}_{+-}$ are suppressed by factors $\Lambda_{\rm QCD}/Q$ and
$\Lambda_{\rm QCD}^2/Q^2$ at large $Q^2$,respectively. We try to discuss the
higher order corrections beyond the pQCD asymptotic predictions by
interpolating an analytical form to the intermediate energy region. From
fitting the data,our results show that the helicity-zero to zero matrix element
$G^{+}_{00}$ dominates the gross structure function $A(Q^2)$ in both of the
large and intermediate energy regions; it is a good approximation for
$G^{+}_{+-}$ to ignore the higher order contributions and the higher order
corrections to $G^{+}_{+0}$ should be taken into account due to sizeable
contributions in the intermediate energy region.
