可变量

And designs a new algorithm which can judge whether or not a given nonnegative integral vector corresponds to a friable trasition sequence. Then the algorithm is used to analyze the reachability of net system which has unique reachable vector or has no T-invariants.

4对可达性与可达方程可满足性相互等价的证明进行补充，给出一个判定非负整数向量是否为可执行向量的判定算法，最后利用该算法对唯一可达向量网和不含T-不变量的Petri网的可达性进行判定。

本研究目标为：改进对栅格交通地图道路信息的识别抽取全过程，使之成为一个输出可测、目标可控、识别过程可自适应优化的闭环反馈识别系统。把对不同图层的识别过程作为并联的子过程控制对象，所构建的整体系统实现了其道路网络输出成为可测变量。

Although in the time series analysis, the theory and method of single variable time series can be extended to multi—variable time series, but it also confronts problems which are not met before.

尽管在时序分析中，有关单变量时序理论及方法大部分都可平行推广到多变量时序分析中，但它也存在着在单变量时序中所不曾遇到的问题。

全局变量可被所有定义该变量为全局变量的函数使用。

The substitution of triangle: used for conditions inequality proof, when given condition is relatively complex, a variable to use another variable representation, then can consider triangle substitution, the two variables are the same parameters.

1三角代换法：多用于条件不等式的证明，当所给条件较复杂，一个变量不易用另一个变量表示，这时可考虑三角代换，将两个变量都有同一个参数表示。

An algorithm is developed, which verifies the estimations for unmeasurable primary outputs with errors between real-measured values and predicted values of secondary variables.

利用可测变量的实测值与预测值的差值对不可测变量估计值进行修正，构成不可测变量的预测推断控制。

We try to introduce the concept of compositive variable and fittness of land-use and to define the spatial value of land, and in order to find the compositive variable for each grid zone by which the land-use for each grid zone can be specified. We apply the the second family theory of multivariate analysis.
