利用黑洞热力学第一定律和第三定律分别导出黑洞的普朗克绝对 熵公式,该公式表明黑洞熵与黑洞视界的全面积成正比. 并进一步证明了黑洞的普朗克绝对 熵就是经典热力学熵.%Using the first and third law of the black hole mechanics, we have derived the form ula of the Planck absolute entrory of the black hole. The formula represents that the entrory of the black hole should be proprotional to the total area of the inner and outer horizons. And we have proven that the Planck absolute entrory of the black hole should be the classical thermodynamic entropy.
