Canonical Ensemble Model for the Black Hole Quantum Tunneling Radiation
  In this paper, a canonical ensemble model for the black hole quantum tunneling radiation is introduced. With this model the probability distribution function corresponding to the emission shell is calculated. Comparing with this function, the statistical significance of the quantum tunneling radiation spectrum of black holes is investigated. Moreover, by calculating the entropy of the emission shell, a discussion about the mechanism of information flowing out from the black hole is given too.
