  In this paper, we find the t and x-evolution of deuteron structure function
from DGLAP evolution equation of singlet structure function in leading order at
small-x assuming the Regge behaviour of the singlet structure function at this
limit and we compare our result of deuteron structure function with New Muon
Collaboration data to find the range of the intercept of Regge behaviour for
deuteron structure function. We also discuss the limitations of Taylor series
expansion method in the Regge behaviour of structure function.
