In this paper, analysing abstract prototypes and the nature of grey number, we consider grey number as nondctcrministic number on definite grey sample, as the abstraction of numerical characteristic, which is known incompletely, of object. To describe grey number completely, we have to determine its grey field and possibility degree model. The later one is an essential describing clement. Degree of reliability of grey number is judged by degree of white ning δok, and the whitening criterion for grey number is given. Using the theory of grey number, we define grey information source as the source whose output is grey number, and grey universal information source as the source whose output is described by grey vector. Thereby we can easily derive the estimates of measures-grey entropy, grey information, grey semanteme recognition information and degree of perception of information source. And we obtain the estimating formula of degree of causality for universal information source.

本文通过分析灰数的抽象原型及本质,认为灰数是依据一定灰样本的不确定数,是对客体未被完全认识数量特征的抽象。对灰数的完整描述,必须确定出其灰域及可能度模型;后者是本质性描述要素(?)灰数的可靠程度,用白化度δ_(ok)判定;并给出了灰数的白化判据。应用灰数理论,把输出为灰数的信源定义为灰色信源,把输出为灰向量的信源定义为灰色普适信源。从而很容易求出各种测度的估计——灰熵、灰信息、灰语义识别信息等及信源感知度。对普适信源的因果度,也得出了估计公式。

It is pointcd out that the tendency of the local point correlation may occur in the conven-tional methods of grey correlation analysis. By introducing the concept of grey entropy de-fined in finite information space, some theorems are developed and the relation between thegrey entropy and the sequential balancing is analyzed.The larger the grey entropy is, thebetter the balance of the series will be. The degree of balance is defined as the ratio of the ac-tual entropy to its maximum value...

It is pointcd out that the tendency of the local point correlation may occur in the conven-tional methods of grey correlation analysis. By introducing the concept of grey entropy de-fined in finite information space, some theorems are developed and the relation between thegrey entropy and the sequential balancing is analyzed.The larger the grey entropy is, thebetter the balance of the series will be. The degree of balance is defined as the ratio of the ac-tual entropy to its maximum value and is the measure of the sequential balancing, The largerthe degree of balance is,the better the balance of the sequence will be. The product of thedegree of balance with the grey correlational level is defined as the degree of approach of thebalance and the grey correlational analysis in connection with it is given. With this method,not only can the local point correlational tendency be eliminated, but also abundant informa-tion provided by point correlational coefficients can be fully utilized.

在实践中经常会碰到有均衡接近性要求的问题,而传统的灰关联分析方法可能产生局部点关联倾向,在引入灰熵概念的基础上,定义了均衡度的概念,把原灰关联度与均衡度相结合给出了实现均衡接近性的灰关联分析方法。

The definition of a kind of grey conditional probability is given in this paper at first. Properties and formulas for the grey conditional probability are discussed. On the basis of above, the definition of the grey entropy is given. Some properties for the grey entropy are discussed.

本文先给出了一类灰色条件概率的定义,并讨论了它的一些性质及有关公式。在此基础上给出了灰色信息论中最主要的概念—灰熵的定义,并讨论了它的一些性质为以后灰信息论的研究和应用奠定些基础。
