时态英语语法中的时态(tense)是一种动词形式，不同的时态用以表示不同的时间与方式。是表示行为、动作和状态在各种吋间条件下的动词形式。因此，当我们说吋态结构的吋候，指的是相应时态下的动词形式。英语吋态可分为16种：一般现在、一般过去、一般将来、过去将来吋，以及这四者的一般时、进行时、完成时和完成进行时。在语法里,时或时态表示行为发生的时间和说话时的关系。一般分为过去式、现在式、将來式，通常也有与表示动作进行或终止的进行式和完成式等体貌一起相连用的情况。动词的现在时一般现在时 (1)一般现在时表示经常性的动作或状态一般现在时表示经常性动作或状态时,常与often, always, usually, sometimes, every day 等时间状语连用。如： The shop opens at nine every day. It seldom snows here. (2)一般现在时表示客观存在或普遍真理 Light travels faster than sound. Food easily goes bad in hot weather. (3)一般现在时表示主语的特征或状态 The picture looks very beautiful. Air contains oxygen and nitrogen.空气含有氧和氮。 (4)一般现在时在时间和条件状语从句中表示将來的动作或状态 I'll tell her about it as soon as I see her. When does the train arrive? (5)用于图片说明或剧本屮的动作提示和背景说明 INSIDE THE SHELTER: Stockton slowly turns to face his wife.

arcgis 时态变化

ArcGIS时态数据应用——动态展示3个月内犯罪案件数量变化【数据准备】情况一：已有数据：派出所辖区的面数据，属性表结构如下，District为辖区编号，其他三个字段分别存储一月到三月的案件数量。图1 一般情况下我们拿到的数据可能都是这样的一种记录方式，其中并没有包含时间信息的字段，并且每个要素只记录了一次。而对于时态数据而言，需要存储每一个时间戳（time stamp）的要素状态，即使是同一个地理要素，也要以多条记录的方式存储，例如下图：图2 如何将手头的数据转换成这样的时态数据呢？难道每个要素都要进行复制吗？对于这种情况，我们可以想办法将表1进行转置，使用ArcToolbox里的Transpose Fields工具来实现，工具设置如下图：

图3 ?Fields to transpose勾选需要转置的时间字段； ?Attribute Fields勾选在就诶过中需要保留的其他字段。注意如果勾选Shape，输出为要素类，否则输出为表格。工具执行结果如下：图4

经过Transpose Fields的处理，每一个要素在每个时间戳都会记录一次，已经基本满足了需要，但是现在TIME字段值还不符合要求，需要进一步处理。利用选择工具选中所有是January的要素，在字段计算器中将TIME字段更改为2011/01，其他两个月也分别用该方法处理。就可以得到图2中的结果了。情况二：虽然时间信息的记录方式是按照图2的形式记录，但是和地理数据分别存储在不同的表格中，那么这种情况就要想办法把两张表格关联起来。对于这种一对多的关系，没有办法直接用join工具，只能用ArcToolbox中的Make query table来间接的实现。需要注意的是要关联的两个数据必须位于同一工作空间下。并且关联之后是一张虚拟的表，需要将其导出。这样就能得到图2的结果了。【数据展示】准备好数据之后下一步就可以来进行展示了，如果我们希望用不同的颜色变化来体现不同月份案件的数量变化，就需要先做符号化。例如用红橙黄绿来表示案件的多少，可以基于CRIME字段用渐变色来表示，划分好区间并设置每个区间的颜色：在图层属性对话框中的time选项卡中进行设置

英语语法基本基础知识——时态

英语的时态问题英语的时态可以分为：“时”(time) 和“体”(aspect)（又称为态）。时是指动作发生的时间，体是指动作发生时的状态。时间与体就象是坐标里的横轴和纵轴，它们的结合交织出了瞬息万变的时空，也构成了英语动词的时态问题。时间分为：过去，现在，将来，过去将来体分为：一般（在某个时间点），进行（延续某个时间段），完成（完成某个时间段）完成进行（延续某个完成的时间段）如此以来，英语中就有16种时态变化，现在就用动词为write例，看看它们的形式。注意：里面的斜体字部分，由于时态过于复杂，几乎没有人真正去应用它们，可以忽略不记。下面就常用的12种时态，（其中还有三种相对用的较少的，请注意）。具体分析一下。一．一般现在时表示现在的时间“点”上发生的动作或者状态，常用于以下的情况 1、经常重复发生的动作或存在的状态，多与often, always, usually, sometimes, everyday, 等时间状语连用。 He takes a walk after supper everyday My mother and father work at the same company. 2、表示性格，特征，能力。 Mr. Smith hates fish and never eats any. 3、表示客观真理或者普遍事实。

The sun rises in the east. 二．一般过去时表示过去某时发生的动作或者状态，常和表示过去某个时间“点”的时间状语(yesterday, last week, 3 years ago, in 1987)连用 She bought a car last week. He came to help me at that time. 三．一般将来时表示将来的时间“点”上发生的动作或者状态。 The train will arrive soon. We shall know the news tomorrow. 四．过去将来时过去某个时间“点”上将要发生的动作或状态。 I asked her where she would spend her holiday. I told my father that I should go home next Monday. 五．现在进行时表示现在的时间“段”上正在延续进行的动作或者状态。 I’m doing some washing. What are you doing? 六．过去进行时在过去某一个时间“段”正在延续进行的动作。 I was working in my office at eight o’clock yesterday evening. He was making a phone call when I saw him. 七．将来进行时在将来某个时间“段”正在发生的动作，一般表示一种猜测和未来的计划，一般不太常用。What will you be doing at 3 o’clock tomorrow afternoon? （明天下午三点你将在做什么哪）八．现在完成时表示动作在一个时间“段”的完成，而且这个时间段是从过去某一点延续到现在的。经常跟时间状语since 1987，for 10 hours , by the last year相连。 My brother has been ill for 3 days. I have not seen her since 1991. 九．过去完成时在过去的某个时间“段”里动作的完成，从过去的一点再到过去的另一点。或者称为过去的过去。 He said that he had written her a letter. Helen rang me up after I had gone to sleep.

时态数据库

1.时态数据库的定义区别于传统的关系型数据库(RDBMS)，时态数据库(Temporal Database)主要用于记录那些随着时间而变化的值的历史，而这些历史值对应用领域而言是重要的，这类应用有：金融、保险、预订系统、决策支持系统等。目前时态数据库还没有像如Oracle、SQL Server等大型关系数据库那样的产品。在当前时态数据库技术尚未完全成熟的现状下，DBMS提供商不会轻易把时态处理功能引入现有的DBMS中，因此，利用成熟的RDBMS数据库，建立时态数据库的中间件，在现阶段是一个较好的选择，因此就应运而生TimeDB和TempDB了。 2.时态数据库的类型时态数据库理论提出了三种基本时间：用户自定义时间、有效时间和事务时间。同时把数据库分为四种类型：快照数据库、回滚数据库、历史数据库和双时态数据库。 1)用户自定义时间：指用户根据自己的需要或理解定义的时间。时态数据库系统不处理用户自己定义的时间类型。因此，用户自定义时间是和应用相关的，不在时态数据库处理的范围之内。 2)有效时间（Valid-Time）：指一个对象在现实世界中发生并保持的时间，即该对象在现实世界中语义为真的时间，包含Valid-From和Valid-To两个值。它可以指示过去、现在和未来。例如，考虑事实?小明从2003年到2007年是大学生?，那么时间区间[2003, 2007]是事实?小明是大学生?的有效时间区间，该事实在该时间区间内为真。有效时间可以是时间点、时间点的集合、时间区间或者时间区间的集合，或者是整个时间域。有效时间由时态数据库系统解释并处理，在查询的过程中对用户透明。用户也可以显式地查询和更新有效时间。 3)事务时间（Transaction-Time）：指一个数据库对象发生操作的时间，是一个事实存储在数据库、或者在数据库中发生改变的时间，包含Transaction-From和Transaction-To两个值。当用户对数据库状态进行更改时，会产生各种操作历史，事务时间真实地记录了数据库状态变更的历史。有时也称事务时间为系统时间。 4)快照数据库：快照数据库是反映现实世界某一瞬间情况的数据模型。它记录了特定时刻的数据库状态。快照数据库采用这样的假设：一个存储在数据库中的元组，一定是真实世界中的有效事实。 5)历史数据库：数据库中被管理对象的生命周期是对象的有效时间，每一个元组记录了数据的一个?历史?状态。历史数据库中没有约束时间的表示方法，可以是时间点的集合、时间区间或者区间集合等形式表示。 6)回滚数据库：数据库中被管理对象的生命周期是事务时间的数据库。它保存了数据库中事务提交、状态演变的历史状态。 7)双时态数据库：数据库中元组包含一个系统支持的有效时间和一个系统支持的事务时间的数据库，称为双时态数据库。双时态数据库具备了快照数据库、历史数据库和回滚数据库的特点，存储了现实世界和数据库系统的变更历史。 8)Now：Now的中文意思是当前时间，是一个时间变元，随着当前时间的变化而变化，记录了随时间变化的信息，它的有效值依赖于当前时间。但在很多应用当中，now 值还能表示?过去?和?未来?时间，这就是now语义的研究课题，它对于提高时态系统查询效率具有比较重要的意义。 3.时态数据库脚本ATSQL的使用时态数据处理构件根据ATSQL2的语法引入了Now、Beginning和Forever三个变元。 Beginning和Forever分别表示时态数据处理构件所能表示的时间起点和终点。Now表示当前时间。每次执行操作时必须使Now绑定到一个固定的值（操作执行的当前时间），
