摘　　要：黑洞不是一颗死亡了的星体,它具有丰富的内涵。黑洞的霍金辐射理论表明,黑洞不仅具有一般的力学性质,而且具有量子性质和热性质。如果黑洞的辐射谱为严格的黑体谱,则黑洞辐射过程中信息丢失。Parikh和Wilczek认为,黑洞的霍金辐射的确可以看成是一种量子效应,但辐射粒子贯穿的势垒不是预先存在的,而是由出射粒子自身产生的。他们的研究结果支持信息守恒。The black hole is not a dead star and it is living and meaningful, Hawking＇s theory of the black hole radiation indicates that the black hole has not only the general mechanical property, but also the quantum and thermal properties, The information may be lost if the radiation spectrum of black hole is exact black body one, Parikh and Wilczek believed that the black hole radiation do can be regarded as a quantum effect, but the barrier to be tunneled is not pre-existed, it is created by the radiated particle itself, Their results support the viewpoint of information con- servation,
