Examples are given to illustrate the conditional entropy maybe increased, so Shannon's definition of information is not absolutely correct.
论文摘要:从新的角度指出了香农信息论和信息定义的局限性,指出了它没有考虑信息的可靠性,完备性等特点,指出条件熵的命名不恰当,香农的"条件熵"应该称为加权平均条件熵,并且举例证明了条件熵可能增加,进而香农信息定义中的不确定性的减少也不是绝对的。

Limitations of Shannon's information theory and information definition are analyzed from new angles. It is pointed out that they didn't consider the reliability, completeness and other characteristics of information, and the naming of conditional entropy is not proper. The correct naming of Shannon's "conditional entropy" should be weighted average conditional entropy. Examples are given to illustrate the conditional entropy maybe increased, so Shannon's definition of information is not absolutely correct.

It is shown that these evolution characteristics in retrograde accretion are very different from those in the prograde case. The temperature of black holes decreases monotonously in prograde case, while it has a maximum in retrograde case. The entropy of black holes always increases in the whole accretion process, and the rates of change of the entropy in retrograde case are much larger than those in the prograde case.
结果表明,黑洞的温度和熵在逆行吸积与顺行吸积中的演化特征很不相同:在顺行吸积中黑洞的温度单调减小,而在逆行吸积中黑洞的温度存在一个极大值;在吸积的全过程中,黑洞的熵始终是增加的,而且逆行吸积中黑洞熵的变化率要比顺行吸积中的黑洞熵的变化率大得多。

Clausius:克劳修斯
自克劳修斯(Clausius)提出属于热力学第二定律的熵定律,也即一个封闭系统的能量只能不可逆地沿着衰减方向转化以后,系统科学把熵的概念改造成自己的范畴,并将系统内各元素之间的协调发生障碍或由于环境对系统的不可控输入达到一定程度时的系统功能紊乱、有序性减弱、无序性增加状态称为"熵值增加效应".
