	Spatial Relationships	空间关系
	So far we have only used spatial functions that measure (:command:`ST_Area`, :command:`ST_Length`), serialize (:command:`ST_GeomFromText`) or deserialize (:command:`ST_AsGML`) geometries. What these functions have in common is that they only work on one geometry at a time.	目前我们仅使用了针对单一几何体的空间函数，包括测量类（如 :command:ST_Area、:command:ST_Length）、序列化（:command:ST_GeomFromText）及反序列化（:command:ST_AsGML）函数。这些函数的共同特点是每次仅能处理单个几何对象。
	Spatial databases are powerful because they not only store geometry, they also have the ability to compare relationships between geometries.	空间数据库的强大之处不仅在于存储几何数据，更在于其能够分析几何体之间的空间关系。
	Questions like "Which are the closest bike racks to a park?" or "Where are the intersections of subway lines and streets?" can only be answered by comparing geometries representing the bike racks, streets, and subway lines.	诸如"距离公园最近的自行车架在哪里？"或"地铁线路与街道的交叉点有哪些？"等问题，必须通过比对代表自行车架、街道和地铁线路的几何图形才能得出答案。
	The OGC standard defines the following set of methods to compare geometries.	OGC 标准定义了下述几何图形比对方法集。
	ST_Equals	ST_Equals
	:command:`ST_Equals(geometry A, geometry B)` tests the spatial equality of two geometries.	:command:`ST_Equals(geometry A, geometry B)` 用于检测两个几何图形的拓扑相等性。
	ST_Equals returns TRUE if two geometries of the same type have identical x,y coordinate values, i.e. if the second shape is equal (identical) to the first shape.	当两个同类型几何图形的(x,y)坐标值完全一致时，:command:ST_Equals 将返回 TRUE，即判定两个图形拓扑相等（空间位置与形状完全重合）。
	First, let's retrieve a representation of a point from our ``nyc_subway_stations`` table. We'll take just the entry for 'Broad St'.	首先，我们从``nyc_subway_stations`` 表中提取 'Broad St' 站点的几何图形表示。
	Then, plug the geometry representation back into an :command:`ST_Equals` test:	随后，将几何图形表示重新代入 :command:`ST_Equals` 函数进行测试：
	The representation of the point was not very human readable (``0101000020266900000EEBD4CF27CF2141BC17D69516315141``) but it was an exact representation of the coordinate values. For a test like equality, using the exact coordinates is necessary.	该点的几何表示（``0101000020266900000EEBD4CF27CF2141BC17D69516315141``）虽不易人工解读，但完整精确地记录了坐标值。在进行相等性测试时，必须使用此类精确坐标表示。
	ST_Intersects, ST_Disjoint, ST_Crosses and ST_Overlaps	ST_Intersects, ST_Disjoint, ST_Crosses and ST_Overlaps
	:command:`ST_Intersects`, :command:`ST_Crosses`, and :command:`ST_Overlaps` test whether the interiors of the geometries intersect.	:command:`ST_Intersects`、:command:`ST_Crosses`和 :command:`ST_Overlaps` 用于检测几何图形内部区域是否发生相交。
	:command:`ST_Intersects(geometry A, geometry B)` returns t (TRUE) if the two shapes have any space in common, i.e., if their boundaries or interiors intersect.	:command:`ST_Intersects(geometry A, geometry B)` 当两个图形存在任意空间交集时返回 t（TRUE），即边界或内部发生相交即视为满足条件。
	The opposite of ST_Intersects is :command:`ST_Disjoint(geometry A , geometry B)`. If two geometries are disjoint, they do not intersect, and vice-versa. In fact, it is often more efficient to test "not intersects" than to test "disjoint" because the intersects tests can be spatially indexed, while the disjoint test cannot.	与 :command:ST_Intersects 相对的是 :command:`ST_Disjoint(geometry A , geometry B)`。若两个几何图形互不相交(disjoint)，则它们不存在任何空间交集，反之亦然。实际上，测试"不相交"(not intersects)通常比直接测试"相离"(disjoint)更高效——因为相交测试可利用空间索引优化，而相离测试则无法利用索引。
	For multipoint/polygon, multipoint/linestring, linestring/linestring, linestring/polygon, and linestring/multipolygon comparisons, :command:`ST_Crosses(geometry A, geometry B)` returns t (TRUE) if the intersection results in a geometry whose dimension is one less than the maximum dimension of the two source geometries and the intersection set is interior to both source geometries.	:command:`ST_Crosses(geometry A, geometry B)` 用于以下几何类型组合的比对：多点/多边形、多点/线串、线串/线串、线串/多边形、线串/多多边形。当同时满足：(1) 交集结果的几何维度比两个源几何的最大维度小1；(2) 该交集同时位于两个源几何内部时，函数返回 TRUE。
	:command:`ST_Overlaps(geometry A, geometry B)` compares two geometries of the same dimension and returns TRUE if their intersection set results in a geometry different from both but of the same dimension.	:command:`ST_Overlaps(geometry A, geometry B)` 用于比对两个同维度几何图形，当满足以下条件时返回 TRUE。
	Let's take our Broad Street subway station and determine its neighborhood using the :command:`ST_Intersects` function:	以下是通过 :command:`ST_Intersects`函数确定「Broad Street」地铁站所属行政辖区的示例：
	ST_Touches	ST_Touches
	:command:`ST_Touches` tests whether two geometries touch at their boundaries, but do not intersect in their interiors	:command:`ST_Touches`用于检测两个几何图形是否边界接触但内部无交集
	:command:`ST_Touches(geometry A, geometry B)` returns TRUE if either of the geometries' boundaries intersect or if only one of the geometry's interiors intersects the other's boundary.	:command:`ST_Touches(geometry A, geometry B)` 当满足以下任一条件时返回 TRUE：两个几何图形的边界存在交集；仅其中一个几何图形的内部与另一个图形的边界相交。
	ST_Within and ST_Contains	ST_Within 和 ST_Contains
	:command:`ST_Within` and :command:`ST_Contains` test whether one geometry is fully within the other.	:command:`ST_Within` 与 :command:`ST_Contains` 用于检测两个几何图形之间的完全包含关系。
	:command:`ST_Within(geometry A , geometry B)` returns TRUE if the first geometry is completely within the second geometry. ST_Within tests for the exact opposite result of ST_Contains.	:command:`ST_Within(geometry A , geometry B)` 当第一个几何图形完全包含于第二个几何图形时返回 TRUE。该函数与 :command:ST_Contains 的检测结果互为逆反关系。
	:command:`ST_Contains(geometry A, geometry B)` returns TRUE if the second geometry is completely contained by the first geometry.	:command:`ST_Contains(geometry A, geometry B)`当第二个几何图形完全被包含于第一个几何图形内部时返回 TRUE。
	ST_Distance and ST_DWithin	ST_Distance 和 ST_DWithin
	An extremely common GIS question is "find all the stuff within distance X of this other stuff".	GIS 领域中一个极其常见的问题是："找出与指定对象距离在 X 范围内的所有要素"。
	The :command:`ST_Distance(geometry A, geometry B)` calculates the shortest distance between two geometries and returns it as a float. This is useful for actually reporting back the distance between objects.	:command:`ST_Distance(geometry A, geometry B)` 用于计算两个几何图形之间的最短距离，并以浮点数形式返回结果。该函数特别适用于需要精确报告对象间距离的场景。
	For testing whether two objects are within a distance of one another, the :command:`ST_DWithin` function provides an index-accelerated true/false test. This is useful for questions like "how many trees are within a 500 meter buffer of the road?". You don't have to calculate an actual buffer, you just have to test the distance relationship.	:command:`ST_DWithin` 函数提供基于索引加速的布尔距离检测，用于判断两个对象是否处于指定距离范围内。该函数特别适用于诸如"道路500米范围内有多少树木"这类空间分析场景——无需实际生成缓冲区，仅需测试距离关系即可获得结果。
	Using our Broad Street subway station again, we can find the streets nearby (within 10 meters of) the subway stop:	以下是通过空间查询查找Broad Street地铁站周边10米范围内街道的SQL示例：
	And we can verify the answer on a map. The Broad St station is actually at the intersection of Wall, Broad and Nassau Streets.	我们可通过地图验证该结论：Broad St 地铁站实际位于 Wall Street、Broad Street 和 Nassau Street 三条道路的交汇处。
