inner action造句

• 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。
• It consists of two parts : the first part ( chapter 2 , 3 , 4 , 5 ) studies the characteristic of elastic waves and surface waves in orthotropic fluid - saturated porous media using biot ' s theory which is based on the substitutive model . in the second one ( chapter 6 ) , a new three - dimensional meso - calculating model , which is more coincided with the inner action mechanism of porous media , is proposed . based on this model , the elastic wave propagation in fluid - saturated porous media under longitudinal impacting is discussed
  论文主要分为两大部分：第一部分基于替代模型的biot理论，对各向异性介质中平面波以及表面波的传播特性进行了研究；第二部分从细观层次出发，提出了一个更加符合含液饱和多孔介质内部作用机理的三维细观计算模型，并对纵向冲击载荷作用下液饱和多孔介质中弹性波的传播规律进行了讨论。
