| 1. | Abstract data flow modeling
抽象数据流建模 |
| 2. | Required system data flow model gives a functional view of the required system
所需系统数据流程模型以功能的观点来探讨所需系统。 |
| 3. | Current physical data flow model describes the functional aspect of the current environment
现时实体数据流程模型描述现时环境的功能。 |
| 4. | After the current physical data flow model is confirmed with users , logicalize it to produce the logical data flow model
与用户确认现时实体数据流程模型后，将之逻辑化，以编制逻辑数据流程模型。 |
| 5. | These options may be supported by technical documentation such as work practice model , logical data model and data flow model
这些选择可能需要某些技术性文件的支援，如工作实务模型、逻辑数据模型及数据流程模型。 |
| 6. | This paper mainly introduces feature of usb , bus system structure , data transmission method , data flow model of usb and usb protocol
本文详细介绍了usb的特点、总线体系结构、数据传输模式、 usb数据流模型、 usb协议。 |
| 7. | Two such viewpoints are represented by data flow modelling ( process point of view ) and logical data modelling ( data point of view )
其中两个审查观点是透过数据流程模型（工序的观点）及逻辑数据模型（数据的观点）来表示。 |
| 8. | This paper mainly introduces the usb work principle ， the communication protocol of usb ， bus system structure , data transmission method , data flow model of usb
本文着重分析了usb总线的工作原理、通讯协议、总线体系结构、数据传输模式、 usb数据流模型。 |
| 9. | However , these two views are static . data flow modelling does not show the sequence of processing while logical data modelling does not indicate how the data changes with time
可是，这两个观点是静态的；数据流程模型没有说明工序发生的先后，而逻辑数据模型则没有说明数据如何随著时间而改变。 |
