Abstract ： When a black hole radiates particles, it losses energy and shrinks, the horizon contracts from its original radius to a new smaller radius. This leads to the separation between the initial and final radii, which sets the barrier for the particles to tunnel. We develop the work of Parikh [Phys. Rev. Lett. 85(2000)5042; Gen. Rel. Grav. 36,(2004)2419] to a Horowitz--Strominger black hole, i.e. applying the Wentzel--Kramers--Brillouin approximation and semi-classical method to calculate the rate of the Hawking radiation. The result agrees with Γ ～ e-2ImI =eΔSBH . It is also proven that the energy spectrum deviates from exact thermality.
