In the frame of Hamilton-Jacobi method, the back-reactions of the radiating particles together with the total entropy change of the whole system are investigated. The emission probability from this processing is found to be equivalent to the null geodesic method. However the total entropy of the system, particles and black hole, is increased yet very little, which is a little different. This method can be applied to any sort of horizons and particles without a specific choice of (regular-across-the-horizon) coordinates. Its physical meaning is more obvious: the negative energy one of a virtual particle pair is absorbed by the black hole, resulting in the temperature, electric potential and angular velocity increase; then the black hole amount of heat, electric charge and angular momentum can spontaneously transfer to the positive energy particle; when obtaining enough energy, it can escape away to infinity, visible to distant observers.
