查询词典 spatial coordinates

The map symbolization is the first key in this model. The spatial data can be compiled through map symbols. For publishing paper map, some approaches, for examples, area feature symbolization, feature covering, making mask and so on, are accomplished on the process. It is the second key that spatial attribute database management is applied in digital mapping.

本文指出解决空间数据的地图表达是实现一体化生产模式的第一个关键，其中地图数据符号化技术贯彻全部过程，实现了基于地图符号的空间数据生产，并在地图出版阶段，通过面状符号配置、要素压盖、蒙片等地图出版处理技术，实现地图出版；本文把属性管理技术应用在地图制图中，实现了属性数据库支持下的地图编辑。

结果表明，高寒草甸土壤水分的空间异质性最高；而高寒灌丛的较低；沙化草地的空间异质性受到多方面外界因素的影响而表现出不稳定的态势。

Coil, Fe, Ni and Zn in spatial variation are identified and the correct assignations are 90.65% for three cluster sites; and (4) based on spatial variations in water quality, it is possible to optimize the monitoring strategy in future with only one of 3 sampling sites and seven discriminant parameters, which can decrease the number of sampling stations and corresponding costs.

coil， Fe， Ni和Zn）可以反映整体水质的空间差异性，且具有90.65%的正确判别能力；④归纳起来，从3类采样点中选择一个或多个、监测7个显著性污染指标即可全面反映后海湾水质管制区的水质空间特征，实现水质监测网络优化。

Gentrification is a social-spatial phenomenon accompanied with urban renewal. However, it is not just a simple social flow and spatial changes, instead, follows the community development and the changes of community characteristic.

中产阶级化是伴随城市更新出现的一种社会空间现象，但这并不是一个简单的社会流动与空间变迁过程，与之伴随的是社区物质条件的改善和社区特性的转变。

In spatial domain, the spatial senses of prepositions are extended.

在空间域里，介词的空间意义得以延伸。

This paper tries to study spatial relations and their linguistic expressions from a cognitive point of view based on the spatial frames of reference and the Figure-Ground relations.

运用认知语言学中的空间参照框架理论和图形－背景关系理论探讨空间关系及其语言表达，具有十分重要的意义。

A Monte Carlo model was used to simulate the spatial and energy distribution of the emission electrons from the micro hollow cathode discharge, based on these results, spatial distribution of the electron in the micro hollow cathode sustained glow discharge was also modeled.

利用蒙特卡洛方法模拟了微空心阴极放电出射电子的空间以及能量分布，并在此基础上模拟了微空心阴极放电自持的辉光放电中电子的空间分布。

And introduces spatial feature, spatial feature relation and geometry attrib. GeoER absorbs some methods from UML.

And then the spatial predicates,possibly used in SDMKD from GIS,are analyzed and listed.Subsequently,the formal expression of spatial assoc...

从G IS数据库中挖掘空间关联规则的主要问题是多层、多关系的规则挖掘问题，不同专题图层不同空间对象之间空间谓词的高效计算与存储表达是解决问题的关键；把空间关系非空间化，将连续数据离散化，从而把求解问题转换成布尔型关联规则问题进行讨论，基于此而探讨了一种通过SJI-P表组织空间谓词，然后根据目标对象的概念层级自顶向下、逐层细化的空间关联规则挖掘方法。
