| 1. | Nasa managers say the space shuttle is in good shape but rain may move into the area around launch time 美国航天局管理者表示空间飞船处于正常状态,但是大雨可能在明天发射时间移至该地区。 |
| 2. | 050 the data that indicates the earth location ( such as longitude and latitude ) of these rendered objects is the spatial data 用于表示空间对象地标(例如经度和纬度)的数据就是空间数据。 |
| 3. | It ' s a general method to construct the symmetry adapted bases of point groups . it has the advantage that the algebraic solutions of point groups can be obtained and the solutions are independent of representation space 它是寻找点群不可约表示的一般方法,不依赖于具体的表示空间,可以得到点群表示的代数解,特别适用于构造分子的对称基。 |
| 4. | Gml ( geographic markup language ) is proposed by opengis consortium to facilitate the interoperation of webgis system , which is an xml specification for the expression of spatial geography information 地理标记语言gml ( geographymarkuplanguage )是opengis组织为解决webgis系统的互操作性而提出的,它是一个基于xml的用于表示空间地理信息的规范。 |
| 5. | Studies show that spatial metaphors are a kind of schema in which the source domain is the spatial concepts and the target domains are abstract and non - spatial therefore , a word with spatial meaning may get some other meanings indicating abstract and non - spatial concepts through spatial metaphors 因此,一个表示空间概念的词语其词义往往在原型意义空间意义的基础上经隐喻拓展而获得许多新的抽象的意义。 |
| 6. | The underlayer spatial database of stadbsii is based on realms and supports dual grid techonology . it can express spatial object discretely and avoid the complexity of spatial redrawing . the underlayer support makes it easier to implement efficient spatio - temporal management and spatio - temporal analysis operations Stadbsii系统的底层空间数据库以realms为基础,同时采用了双网格技术,在离散表示空间对象的基础上避免了复杂的空间调整,为实现高效的时空存取以及时空分析操作提供了底层保证。 |
| 7. | We consider all kinds of plane line representations of a plane line , and a simple and practical line coordinate system is suggested . we also present a new 3 - d line representation model . the new representation model is based on the geometry theory : the intersection of two arbitrary planes in the 3 - d space is a line in a plane 本文提出了直线坐标的概念,通过分析各种平面直线的表示方法,提出了一套简单而实用的直线坐标表示方法,提出了一种新的空间三维直线表示法,这种表示空间三维直线方法是根据空间相交两平面一般交于一条空间直线的思路而提出的。 |
