一次性评定对象表达式的值以访问其多个成员 - Starting from the problem in the spatial data model of webgis nowdays , this paper analysizes and designs spatial data model , and builds a united spatial data model and oriented object expression
论文首先从当前webgis空间数据模型当前普遍存在的问题出发，分析和设计了空间数据模型，建立了数字地球需要的统一数据模型与面向对象表达。 - In shape analysis , we get feature units of shape , that is , arc segments and straight - line segments through segmentation and identification of digital curves and the following combination of the same features , and present a new method of object expression and recognition based on straight - line segments
在形状分析中，通过曲线分割、分段识别以及相同特征的合并来提取形状特征基元，即弧线段和直线段，提出一种基于直线段的目标描述和识别方法。 - Although uml activity diagram is magnitude component in uml , which agrees with modeling system dynamic process and describing workflow , it is immature in itself with the characteristic of non - oriented - object and essentially different from other uml diagram , and need to be ameliorated especially when applicated in workflow , own to the following limitation : firstly , activity diagram describes the behaviors of object class that response the inner action , so uml activity diagram is generally on the assumption of that there is no interruption caused by outer events during the process and no time defer , which limits the ability of uml activity diagram discribing complicated process ; secondly , user cannot obtain enough information of object data , and cannot make sure the character of mutual objects because of actually complicated object and relatively simple object expression in uml activity diagram ; lastly , owe to lacking rigorous mathematical basis and strict , effective methods of validation and analysis , uml activity diagram cannot support the simulation and optimization of workflow , let alone optimizating the model based on the result
Uml活动图是uml的重要组成部分，适用于系统动态行为建模和描述工作流，与uml的其他图形工具不同，它本质上是非面向对象的，而且其本身并不成熟，仍在改进之中，特别是在工作流应用方面。首先， uml活动图描述的是响应内部处理的对象类的行为， uml活动图通常假定在整个计算处理的过程中没有外部事件引起的中断，也没有时间的延迟，这就限制了uml活动图对一些复杂过程描述能力。第二，现实世界业务过程涉及的对象数据十分复杂，但是uml活动图的对象语义却非常简略，用户基本上无法从uml活动图中获取关于对象数据的信息，也不能确定参与交互的对象的特征。
