查询词典 relations

Containing the Visible Region positioning and the Sequence Region positioning raised in this paper as well as the Orientation Region positioning raised by Levitt [17] , the qualitative positioning method segments the environment of robot into different equivalent classes , and describes the positions without coordinates but just using landmarks and landmark relations, based on the extracted qualitative relations from images such as the visibility of landmarks, the sequence of landmarks and the position relative to the landmark pair boundary .

定性定位包括本文首次提出的可见区域定位和顺序区域定位，以及Levitt[17]提出的有向区域定位，利用通过图像获取的路标的定性关系如路标的可见性，路标排列的顺序和相对于路标对边界的位置等，将机器人的运动环境划分为若干个等价类；其定性性体现在不必使用坐标就可描述机器人的位置，这种定位方法只利用视觉反馈中的定性信息。

Through analysing, we found that the average P/E ratio of industry, ROE, expenses rate are the factors influencing function to be relatively remarkable to company P/E ratio; The relations between company P/E ratio and such indexes as ROE, etc are all negative relevant, it is opposite to analyse with the theory, this kind of conclusion that completely contradicts proves the development of the stock market of our country is still at very unripe stage, the phenomenon that the high-quality stock is underestimated is serious, the whole market has even turned around; P/E ratio and net assets factor are in close relations, this includes the price of evaluation on net assets, rentability of the net assets, etc.

其次是对公司市盈率影响因素的分析，本文考虑了21个可能的影响因素，通过分析发现行业平均市盈率、净资产收益率、费用率等因素是对公司市盈率影响作用相对显著的因素；净资产收益率等指标与公司市盈率都是负的相关关系，与理论分析相反，这种截然相反的结论说明我国股市的发展还处于很不成熟的阶段，优质股票被低估的现象严重，整个市场甚至倒了过来；市盈率与净资产因子的关系密切，这包括了净资产的收益性、净资产的成长性以及股市上对净资产的评估价格等。

Fifthly,as far as the deep layer of philosophy is concerned,Maoexposed limitations toward the understanding of fundamental contradictions.On onehand,he exaggerated the retroaction of production relations and superstructure.Heregarded"superstructure→production relation→the development of productivity"asthe general rule of socialist revolution and construction,the essential of which was toimpel the constant improvement of the socialization degree of production material bymeans of class struggle so as to promote the development of productivity.On the otherhand,Mao had not correctly commanded the specific manifestation of the fundamentalcontradictions.He attributed"the inadaptability of productivity to production relations"to the phenomena that socialization degree of ownership was not high enough,its scalenot large enough,and its nature not pure enough.He also attributed superstructureproblem to the fact that"capitalist-roaders"had usurped a part of leadership from thegrass-root level to the central level.

其一是对基本矛盾理解的局限性：一方面夸大生产关系、上层建筑的反作用，把先上层建筑、再生产关系、再发展生产力当作社会主义革命和建设的一般规律，其实质是通过阶级斗争，推动生产资料公有化程度的不断提高，认为这样就能促进生产力的发展；另一方面是没有正确把握基本矛盾的具体表现形式，把与生产力不相适应的生产关系方面主要归结于所有制的公有化程度不够高、规模不够大、性质不够纯，上层建筑方面主要归结于资产阶级、反动势力的存在，后来则认为"走资派"篡夺了从基层到中央的部分领导权。

Second indication of choice: the relations, the set of relations, or rather, the set of procedures whose role is to establish, maintain, and transform mechanisms of power, are not "self-generating"* or "self-subsistent"; they are not founded on themselves.

其次，选择的提示是：各种关系，各种关系的整合，更确切的说是各种程序的整合，它们所扮演的角色是建立、维护，与转换各种权力装置，它们既不能"自生"也无法"独存"；它们不是建立在自身之上的。

The traditional query tree optimization methods,parallel database optimization methods based on left linear trees and right linear trees,bushy trees,and operation of the forest,have their own pros and cons,they have been more in-depth and maturity of the study.The query optimization method based on multiple weighted tree has studied its model of parallel query plan,its complexity model of parallel query plan and query optimization algorithms.The semantic query method transforms an inquiry into one or several semantic equivalence inquiries then has to find and implement a strategy to achieve a better query.Agent-based parallel database query optimization using Multi-Agent technology to automatically search the integrity constraint conditions which are related to the determined query,there for,the efficiency between several relations' joins has been greatly improved.The parallel optimization algorithm,based on genetic algorithm which is suitable for multi-joins of cluster environment,has deeply studied the relations storage options,multi-joins query optimization and query processing and other key technologies based on cluster parallel database.

传统的查询树优化方法，即基于左线性树、右线性树、浓密树、操作森林的并行数据库查询优化方法，各有优劣，对其的研究比较深入、成熟；基于多重加权树的查询优化方法，研究了其并行查询计划模型、并行查询计划的复杂性模型和查询优化算法；语义查询优化方法将一个查询变换成一个或数个语义等价的查询，进而寻找并执行这些等价查询中具有较好实现策略的一个；基于Agent的并行数据库查询优化采用Multi-Agent技术自动查找与给定查询有关的完整性约束条件，使得多个关系间连接操作的效率得到很大的提高；基于遗传算法的并行优化算法，深入研究了基于机群并行数据库中关系存储的选择、多连接查询优化和查询处理等关键技术。

This paper aims at the prominent issue that current models of spatial topological relations can not represent complex object, among which 9-Intersections Model (9IM) is well known. Therefore, taking cadastral data as example, one model of topological relations between complex and spatio-temporal objects based on 9IM is put forward. And the improved sweep-line algorithm is designed. Specific studies as follows:(1)According to the concepts of point set topology, the author distinguishes the complexity of the object, redefines the spatial point, line and region. For instance, in the simple region, concave one is more complex than convex, composite regions can be composed of many parts or with holes, and so on.

本文针对当前空间拓扑关系模型无法表达复杂对象的突出问题，以地籍对象为实例，以9I模型为基础，探索了一种适合复杂对象和时空对象的拓扑关系表达模型，较好地解决了地籍对象中各类要素间拓扑关系的描述和应用，实现了地籍变更中变化语义类型的推理和历史回溯；通过对现有的拓扑关系计算方法进行了改进，设计了相关算法，给出了C语言程序示例；最后通过实验系统的实现，验证了模型和算法的可行性。
