The FCS calculated for a given service data unit is dependent on the media access control method. 为给定服务数据单元计算的FCS依赖于介质访问控制方法。
Labor ensures service or the tax authority is OK record, recording, kinescope, take a picture and duplicate concerned data; but, ought to expend an unit to keep secret for capture. 劳动保障行政部门或者税务机关可以记录、录音、录像、照相和复制有关资料;但是,应当为缴费单位保密。
Quantitative assessment on the service reliability of oil-pumping unit can be made by establishing a service life model through statistical processing of field fault data of oil-pumping unit and digital simulation by using the Monte-Carlo method. 通过对潜油电泵机组现场故障数据的统计处理,运用Monte-Carlo统计模拟法,进行数字仿真,得到系统使用寿命统计模型,实现对潜油电泵机组使用可靠性定量评定。
In Service Unit Network Architecture, the processing of the real-time data includes applications software and real-time transport service unit. 服务元网络体系结构中对于实时数据的处理,包括应用程序部分处理及实时传输处理两在部分。
In this article, firstly, it analyzed the characteristic of AOS system, its data handling service, the grades of the service, the layered structure, the data unit structure, the data transmission process. 本文阐述了AOS的体制特点,分析其业务种类、业务等级、分层结构、数据单元结构、数据传输过程;
In view of work feature of thyristor counter-parallel, the item designed overvoltage detecting circuit and corresponding interrupt service subroutine. According to the acquisition data that from gathering unit, it designed tap-changer transfer subroutine and thyristor triggering subroutine. 针对晶闸管反并联的工作特点,设计了电压过零检测电路及相应的中断服务子程序;根据数据采集单元采集到的数据设计了分接开关转换子程序及晶闸管触发子程序。
Adaptive Workflow Management System should make judgment on conditions of service exceptions, which mainly based on two aspects, the time that data stays in an organization unit of the workflow is more than expected and the output data the activity exports Report exceptions. 自适应工作流管理系统需要对服务异常情况做出判断,这种对异常的判断主要基于两方面:数据在某一组织单元工作流程内流转的时间超出预期范围,以及该组织结点输出的数据结果异常。
In this thesis, we investigate the performance improvement of the MAC protocol by using the two frame aggregation techniques, namely A-MPDU ( MAC Protocol Data Unit Aggregation) and A-MSDU ( MAC Service Data Unit Aggregation). 在本文中,我们利用两个帧聚合技术,即A-MPDU(MAC协议数据单元聚集)和A-MSDU(MAC服务数据单元聚合),来探讨MAC协议的性能改进。
