| 1. | When an interval is imaginary, we say that the two points have a space-like interval between them . 当间隔为虚数时,我们说这两点之间有一个类空间隔。 |
| 2. | Boundedness of weighted composition operators between bloch - type spaces 类空间之间的加权复合算子的有界性 |
| 3. | A method of grey cluster spatial prediction of rock - mass slope stability based on artificial neural network and its application 基于神经网络的岩体边坡稳定性的灰色聚类空间预测法及其应用 |
| 4. | In this paper , we focus on the structure of r - tree and bucketfile , and the algorithm of three kinds of spatial queries 本文重点讨论了r树、 bucketfile两种空间索引的基本结构及三类空间查询在其上的算法实现。 |
| 5. | We summarize that spatial index system should provides three kinds of spatial query , they are , spatial range query , nearest neighbor query , spatial join query 本文总结出空间索引系统应提供的三类空间查询:空间范围查询、最近邻居查询、空间连接查询。 |
| 6. | This type of topological space is go - space or their products . the special ordinal structure of go - space provide people extensive space to imagine and plot 这类空间就是go -空间或其乘积, go -空间特殊整齐的序结构给拓扑学家们提供了广泛的想象和构思的空间。 |
| 7. | Beijing along with cities all over china are also experiencing a growth in demand for these spaces activities exemplified by wang fu ji in beijing and nanjing road in shanghai 北京和其他城市都在经历着对此类空间的需求增长,比如北京的王府井,上海的南京路。 |
| 8. | There are two important kinds of special objects in mine information system , that is to say , digging roadway and stratum . roadways are the thoroughfare that transport coal form the working face to ground , ventilate , and carry workers safely 矿山信息系统主要面对两类空间目标,即掘进巷道和地层,巷道是采矿生产中将煤炭从工作面运送到地面,以及通风、安全输送工人的通道。 |
| 9. | Two kinds of multi - resolution spatial data model are studied in this paper . one is the feature model and hoom model based on dlg data . the other is multi - resolution dem model based on terrain data using the algorithms of self - adaptive triangular regular networks and hierarchical triangular irregular networks 论文主要对两种类型的多分辨率空间数据模型理论和实现技术进行研究,第一类空间数据是数字线划图数据dlg ,第二类是数字高程模型数据dem 。 |
| 10. | And hbds model is extended to hoom model . hoom is an objected - oriented integrated spatial model , which integrated geometric model , geographical feature model , geographical representation model , spatial calculation model and temporal model that based on hypergraph model . a normal object - oriented multi - resolution model is proposed to manage integrated multi - resolution spatial data that is dlg and dem data 这两类空间数据的建模方法存在较大的差异,第一类数据的建模是通过特征模型和超图对象模型实现的,第二类数据的建模是通过对自适应规则三角形和不规则三角形的简化与细化算法的研究实现的。 |
