  In this paper,using Hamilton-Jacobi ansatz, we investigate scalar particles
tunneling radiation in the Demianski-Newman spacetime. We get the effective
temperature with influences of quantum gravity, and compare this temperature
with the original temperature of the Demianski-Newman black hole. We find that
it's similar to the case of fermions, for scalar particles the influence of
quantum gravity will also slow down the increase of Hawking temperatures,which
naturally leads to remnants left in the evaporation.
