While we do not need to register the file representation component , we are required to make some security assertions about the object ' s methods and properties 然而我们并不需要注册文件表示组件，我们被要求做一些关于对象方法和属性的案例声明。
If you are developing an application that will run under this account , be aware that db2 udb has restrictions on objects with schema names starting with " sys " 如果开发在该帐户下运行的应用程序，必须知道db2 udb关于对象模式名以“ sys ”开头的限制。
The key thing to note in any discussion of aop and performance is that the arguments against the performance of aop implementations are similar to the ones made against objects years ago 在aop和性能的讨论中，需要重点关注的是关于aop实现的性能的争论，它们与若干年前关于对象性能问题的争论类似。
If you have used visual basic for a while , or if you have worked through the examples in the documentation , then you have already programmed with objects , but there is a lot more to objects than what you have seen so far 如果您已经使用了visual basic一段时间，或者如果已经演练了此文档中的示例，则已经使用对象进行编程了，但到目前为止还有许多您未看到的关于对象的内容。
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。
Abstract : in the viewpoint of proposition logic and based on extensiontheory , a new method for proposition representation is proposed . the proposition representation of matter - element , affair - element and matter - affair - element is set up , which shows that a matter - element is equivalent to a descriptive proposition and an affair - element or a matter - affair - element to an action proposition . and then , the extensibility and the transformation of propositions are discussed . finally , the concept of proposition extension set is given based on extension set 文摘:从命题逻辑的角度，以可拓论为基础，建立了命题表示的一种新方法，提出了物元命题、事元命题和事物元命题的概念；指出物元命题与关于对象的陈述型命题相对应，事元命题和事物元命题与关于行为、事件的行为型命题相对应；探讨了命题的可拓性和可拓变换方法；给出了基于可拓集合的命题可拓集的概念
