Abstract: Although the intensive explanation for the puzzle of the information loss needs the quantum gravitation theory or the string theory,the semi-classical tunneling method is used for investigating the tunneling radiation characteristics of the spherically symmetric charged black hole.The result shows that the tunneling rate is related to the change of the Bekenstein-Hawking entropy and the radiation spectrum is not strictly thermal.Thereby the information loss is possible,which satisfies the underlying unitary theory of the quantum mechanics.And it provides not only a further modification to the Hawking radiation spectrum but also a new method to study the quantum tunneling radiation of charged particles.
