1.SymbolSFor a closed thermodynamic system, a quantitative measure of the amount of thermal energy not available to do work. 2.A measure of the disorder or randomness in a closed system. 3.A measure of the loss of information in a transmitted message. ...
The resulting small entropy production of Δs1+x = 0.0009 kJ/kg K can be understood as mixing irreversibility in addition to entropy which is produced by heat exchange between warm air and evaporating water. Even this simple device behaves just like a heat exchanger and produces entropy. View...

联合熵(Joint Entropy):表示为两个随机事件X和Y的熵的并集,联合熵解决将一维随机变量分布推广到多维随机变量分布。 公式定义: 互信息(Mutual Information, 信息增益):两个随机变量X和Y,Y对X的互信息,为后验概率与先验概率比值的对数,即原始的熵H(X)和已知Y的情况下的条件熵H(X|Y)的比值的对数,信息增益越大...
while theKMvalue was 0.98 mM for H2O2and theVmaxvalue was 1.06 × 10−8 M s−1(y = 0.925x + 0.944,R2 = 0.981). The lowerKMvalue for H2O2indicated that CoPdPt has a higher affinity to the substrate than that of horseradish peroxidase (HRP) (3.70 ...
The paper discusses the possibilities of using entropy in company management. Entropy as a phenomenon has been used in the past mainly in natural sciences, especially in thermodynamics. This new approach was used by Czech manager and management theorist A. Kopaj, who called his approach and opini...

若X连续: H(X)=∫X∈χ−p(X)log(p(X))dX 而互信息熵则是用于衡量一个随机变量X所能提供的关于另一个随机变量Y变化信息的无量纲统计量(一般单位为bit),换一种说法,即随机变量X所能带来的对随机变量Y不确定度的减少程度: Mutual information is one of many quantities that measures how much one ra...
Glass-to-glass transitions are useful for us to understand the glass nature, but it remains difficult to tune the metallic glass into significantly different glass states. Here, we have demonstrated that the high-entropy can enhance the degree of disorde
