  In this paper, we obtain some new explicit travelling wave solutions of the
perturbed KdV equation through recent factorization techniques that can be
performed when the coefficients of the equation fulfill a certain condition.
The solutions are obtained by using a two-step factorization procedure through
which the perturbed KdV equation is reduced to a nonlinear second order
differential equation, and to some Bernoulli and Abel type differential
equations whose solutions are expressed in terms of the exponential and
Weierstrass functions
