查询词典 autonomous variable

This represents a fundamental mathematical limit on the best possible lossless data compression of any communication: considering a certain message as a series of realisations of a certain random variable (where the random variable can be "the next letter", or "the next word", or any other subdivision of text), the shortest number of bits necessary to transmit one message is the Shannon entropy of the corresponding random variable, multiplied by the number of realisations in the original text.

当然如果各个队夺冠的几率不等的话，那么熵则不会是5。因为如果从强队开始问问题，则不需要5个问题一般就可以得到答案。而根据哈夫曼编码的启发，我们表示这32个队，不需要平均长度为5的二进制位。从另外一个角度来看，熵作为信息量的大小也是表达能力的衡量，或者是不确定度的衡量和混乱程度的表现。为什么选择log来表示熵呢？如果X的表达能力为H，Y的表达能力为H，那么X+Y的表达能力应该是二者的乘积，所以H = H + H。

In order to prove the global asymptotical stability of the endemic equilibrium, we introduce the change of variable which can reduce our original four-dimensional system to a three-dimensional asymptotical autonomous system with limit system.

Thirdly, as the result of this research, the author points out that the following competitive and dynamical evolving network should be the target of Chinese IOS: 1 The network is dominated by oligopoly; 2 Large, medium and small-sized enterprises co-exist in the network; 3 This network structure is realized through market adjusting, and it should be the result of autonomous evolution of IOS; 4 As to the realization of this network structure, government only is an exogenous variable and its function is to create the external condition to promote the evolution of IOS.

所以论文提出了我国产业组织结构演进的目标状态应该是"寡头主导，大、中、小共生"的竞争动态演进型产业组织结构，同时强调这种产业组织结构的实现应该是在市场机制的调节下、在产业组织结构的自发演进中实现，政府的作用空间仅仅是为其实现创造外部条件，不可人为安排一种市场结构。
