  Observations show that there are twisted magnetic flux tubes and plasma flow
throughout the solar atmosphere. The main purpose of this work is to obtain the
damping rate of sausage modes in the presence of magnetic twist and plasma
flow. We obtain the dispersion relation for sausage modes in slow continuity in
an inhomogeneous layer under the conditions of magnetic pores, then we solve it
numerically. For the selected density profile, the magnetic field, and the
plasma flow as a function of radius across the inhomogeneous layer, we show
that the effect of the twisted magnetic field on the resonance absorption at
low speed of the plasma flow is greater than one at high speed.
