零星

For this to be or not to be situation,local officials always issued countermeasures for the things occurred to construct and maintain commercial orders,which reveals the temporariness,and disorder,anyway the scattered efforts became the basic protection from public power for the development and prosperity of industry and commerce in Qing Dynasty.

正是因为这种两难境地，所以地方官府构建及维系商业秩序的种种措施多是针对一时一事作出的被动消极的应对之举，表现出一定的临时性、凌乱性和繁杂性，但随着时间的推移，这些零星的努力积累起来，依然为清代工商业的发展与繁荣提供了最基本的公权力保障。

But these last ragged tidbits of the winter world from which I'd come faded.

但这些来自于我那寒冷国度的零星记忆己慢慢从我脑海中消褪并被遗忘。

In 1450, most Europeans probably lived in villages, but some regions were so hilly, l acking in good soil, or heavily timbered that villages could not keep going, and settlement was that of solitary herdsmen or shepherds.

年，大多数欧洲人或许都住在村落里；但是，有些地区丘陵起伏，土壤贫瘠，森林茂密，难以形成村落，只有零星的牧民居住。

This stage in a child's life is accelerated, like time-lapse photography, going from infancy to running around, saying words, trying to talk.

就像会随着时间褪色的照片，这段时间在儿童的生命中加快，小孩由婴儿期长到能爬、说着零星的字眼，学着去讲话。

After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.

具体研究工作及成果如下：（1）根据点集拓扑理论中与拓扑空间相关的概念，本文对空间的点、线、面进行了重新定义，以区分对象的复杂性；分析了9I模型在表示简单对象方面的优点，以及在表达复杂对象上的不足，阐述了本文的研究思路和解决方案，并以复杂的面面、线线和线面为例详细探讨了复合拓扑关系的表达方法；（2）分析了地籍权属数据和地类数据的内涵、特点和要素之间的联系，根据复杂对象的拓扑关系表达模型，本文讨论了宗地、界址线、界址点之间，图斑、线状地物、零星地类之间可能存在的拓扑关系和形式化表达方法，归纳总结了地籍对象的拓扑关系满足的约束性规则；（3）将拓扑关系的研究延伸到时空领域，从地籍对象的时态性出发，本文阐述了地籍数据中时间的含义和变化语义描述的需要；从时间、位置、状态、事件等之间的拓扑关系方面，重新系统性地进行了时空拓扑关系的定义；研究了一维时间和二维空间的集成表达方式，以宗地、界址线为例，分析了变更前后不同时间区间里可能的拓扑关系，探讨了时空拓扑关系对时空变化操作类型和变化语义的推理方法和意义；（4）为实现空间拓扑关系的查询分析等应用，本文研究了空间拓扑关系的计算方法。

At first there was only a trickle of people, but soon a crowd arrived.

Wang gave up only four hits last night, but was uncharacteristically wild, walking four.

Natural forests were all destroyed. The main vegetation types are only Sophora davidii, Ostryopsis davidiana undershrub etc. and Hippophae rhamnoide, Populus simonii and Robinia pseudoacacia etc. built to restore the environment.

天然森林已全部遭受破坏，植被类型主要为零星分布的旱生小灌木狼牙刺、虎榛子等及以生态修复为目的的人工林沙棘、小叶杨、刺槐等。

In China,natural lacquer has been studied for a long time.Because to separate natural homologous is very difficult,it is almostimpossible to obtain a great deal of pure sample.So the structure ofmain constitute of Chinese lacquer urushiol has not an identicalresult due to the incomplete structural data. The urushiol diacetate derived from urushiol have beensuccessfully separated using centrifugal rotational TLC withpreparative silica get thin layer coated silver nitrate.

天然漆的研究，在我国有较长的历史，漆酚组分及结构做过一些工作，但由于天然同系物之间分离的困难，不易大量得到纯的样品，只能通过零星结构数据推断结构，致使中国生漆漆酚主要组分的结构没有一致的认识与确切的结论。
