约束变量

One constraint on placing declarations is that variables are accessible from the point of their definition until the end of the enclosing block.

放置声明的一个约束是，变量只在从其定义处开始到该声明所在的作用域的结束处才可以访问。

To overcome the shortcomings of existing algorithms, the distributed parallel reactive power optimization algorithm based on sub-area division of the power systems is proposed according to the distributed and decentralized characteristics of the power system. Here, multi-objective function and soft constraints are modeled using fuzzy sets, and the multi-objective reactive power optimization problem is solved by the direct nonlinear primal-dual interior point algorithm.

With respect to syntax, the roles of tagmeme in the structure of word and sentence and Chomsky's Generative-Transformational Grammar are discussed. The spatial relation theory and existing research achievements are investigated. Having noticed the shortage of the capability of topological and metrical relation in the description of spatial information structure, the author proposes Combinational Qualitative Geometry based on the two invariables under ordinary transformations, distance ratio and direction difference, the CQG-based spatial relation system between topological and metrical constraint is thus constructed, on which several spatial relations such as parallel, perpendicularity, co-linearity, sequence and direct neighborhood are derived. Based on extended theory of spatial relation, the language anamorphosis is analyzed from the aspects of phonetics, semantics and syntax. The mere geometric and formalized spatial relation is then integrated with concrete geographic ontology to accommodate richer and indicative spatial configuration of spatial information in the different geographic context. Finally a syntax framework for spatial information is put forward.

在语法结构方面，首先阐述了法位和法素在语法结构词法和句法中的地位和作用，以及Chomsky生成转换语法的核心内容；详细介绍了地理信息系统空间关系理论及现有的研究成果；在分析现有的拓扑关系和量度关系对空间信息结构描述能力不足的基础上，提出了基于长度比和角度差两个不变量的组合定性几何，以此建立了介于拓扑及量度约束之间的组合定性关系体系，并以此为基础派生出平行、垂直、共线、次序、直接邻近等空间关系描述；本文基于扩展的空间关系理论，详细讨论了空间关系在语音、语法和语义三个方面的语言变体，将纯几何和纯形式化的空间关系与具体的地理本体结合起来，可以获得更为丰富的、更能反映空间关系在不同语言上下文中具体体现的组合关系；最后给出了一个空间信息的语法结构的基本框架。

The construction of traditional models for batch scheduling relies on the definition of time slots or time events.which lead to the result that many binary variables are involved in the models and it takes much time to solve the problems with the branch and bound method.

而传统的生产模型，由于太过于依赖计划时间的精确度和事件点，因此将大量的时间都花在了对整数变量和约束方程的求解问题上。

Erection parameters in the literature [9] nonlinear analysis method used to calculate some of the variables erection capacity limit, but no major erection of some other variables, such as the level of the top-Ligan excess of the limit load length the impact of, and the top model Ligan more displacement constraints, and the actual situation of access to a certain extent; literature [7] space will be just as Falsework framework erection of the main parameters of the critical load, and The literature [10] scaffold for the ultimate strength estimation method for calculating the results of the amendment.

在搭设参数方面，文献[9]采用非线性分析方法，计算了部分搭设变量下的极限承载力，但是没有分析另外一些主要搭设变量如立杆超出顶层水平杆长度对极限承载力的影响，而且计算模型的顶部立杆位移约束较多，和实际情况有一定的出入；文献[7]将模板支架视为空间刚框架，分析了主要搭设参数下的临界荷载，并采用文献[10]提出的用于外脚手架极限承载力的估算方法对计算结果进行了修正。
