查询词典 conditional entropy

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.

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。

In the procedure of gymnastics athletes' U.C., the functions of the conditional ability performing now are more and more important in the competitive abilities of the floor exercises; besides the sport technique and conditional ability, one should pay attention to the figure in the pommel horse; the importance of the conditional ability is far above the sport technique , and the requirements of the figure are also high in the rings; the characters of competitive abilities of the vaulting horse are similar to those of the floor exercise, in which conditional ability plays a very important role; the requirements of the sport technique in the parallel bars are above those of the conditional ability; the requires of sport technique in the horizontal bar are strikely above those of other individual events, and the psychological ability is above the conditional ability; uneven bars contains much techniques, which means, sport technique is above the conditional ability; balance beam also contains much techniques and requires the least in the conditional ability in women's events, but this individual event demands psychological ability badly. Therefore one should emphasize on the cultivation the psychological ability when U.C. is applied to the balance beam.

体操各单项在实施非衡结构补偿过程中，自由体操各竞技能力中运动素质发挥着越来越大的作用；鞍马注重运动技术和素质外，还应注意形态要求；吊环中运动素质的重要程度远大于运动技术，对形态的要求也很高；跳马与自由体操的竞技能力特点类似，运动素质的作用非常大；双杠对运动技术的要求高于运动素质；单杠对运动技术的要求明显高于其它诸项要素，对心理能力的要求甚至略高于运动素质；高低杠技术性很强，对运动技术的要求高于运动素质；平衡木技术性较强，对运动素质的要求不如女子其他各项高，但对心理能力的要求非常高，在实施非衡补偿时，应注意对心理能力的培养。

Also this paper gives a definition of quantum conditional entropy of entanglement E_ A｜Band proves that it satisfies the four fundamental conditions of a entanglement measure for a kind of mixed state of 2×2 quantum system by this negative quantum conditional entropy Using conditional entropy of entanglement,this paper investigates the quantum entanglement between the two identical two-level atoms simultaneously interacting with vacuum cavity field as an application.

Entropy increase principle in isolated system, which is deduced from the discussion of Clausius entropy and Boltzmann entropy, has further deduced entropy principle in open system as well.

通过对克劳修斯熵、玻耳兹曼熵的讨论，得到熵的本质和孤立系统的熵增加原理，并把孤立系统的熵增加原理推广为开放系统的熵原理。

This paper analyzes the informational entropy and the conditional entropy,and studies the entropy deeply as an indefinite measure of the battlefield information.

熵是度量信息有效性和可靠性的重要理论工具，分析了信息熵和条件熵，并深入研究了熵作为不确定性的度量在战场情报中的评估应用，最后举例说明了既要考虑信息的价值又要考虑其风险程度这一新的情报分析方法，使得决策过程透明化，降低了决策的风险。

The results indicate that conditional EVT is superior to other models;conditional distribution model is superior to conditional normal model;conditional EVT for confidence ...

结果表明，条件EVT比其它模型的测度效果好；条件t分布模型优于条件正态分布模型；置信水平为99%的条件EVT和置信水平为95%的条件t分布模型，分别是测度上证A、B股市场风险效果最好的模型。

The conditional symmetry instability is the intermediate process between the stable and instable states of the atmosphere. The evolution of the atmosphere from the stable to unstable state or from unstable to stable state comes through two stages. The convective-symmetric instability circulation is related with the state and type of the instability. When the conditional instability lies in the lower level and conditional symmetric instability in the upper level, the circulation will have vertical updrafts in the lower level and slantwise updrafts in the upper level. The release of conditional symmetric instability gives rise to a mesoscale rain belt.

结果表明：条件对称不稳定是大气稳定状态和条件不稳定状态之间的中间纽带，大气由稳定向不稳定或者由不稳定向稳定的演变均通过条件对称不稳定来实现；对流对称不稳定环流的形成与不稳定层的配置有关，当低层为条件不稳定而高层叠加深厚的条件对称不稳定时，对流对称不稳定环流低层出现垂直上升气流，高层出现范围较广的倾斜上升气流，对称不稳定能量释放产生中尺度云带。
