数据流

Most of all, the coordination of activity, the management of dataflow, the dynamic binding of services, transaction and exception handling, the verification and optimization of workflow, and the monitor of workflow running consist of the main parts.

其中，主要包括活动的协调、数据流管理、服务的动态绑定、事务性与异常处理、流程的验证和优化以及流程运行的监测等方面的内容，针对这些问题，文章从工作流生命周期的角度出发，并结合具体相关的研究项目作出较为深入的分析，并指出了可行的解决方向。

The technology of multicast in Stream Media has more advantages when it is applied for the application of direct living broadcast through IP network or IP television. It can make the media server send continuous data to more than one customer client synchronously without any delay or broadcast storm. Therefore it can improve the availability of the network system.

针对在IP网络上网上直播和IP电视等应用，流媒体传输技术中的多播技术具有更大的优势，它能让媒体服务器同时向多个客户端发送连续数据流而不产生延时，但又不会产生广播风暴，极大地提高了网络利用率。

By using the method for positive term resolution of equations of higher degree, all non-zero real roots of a real coefficient equation of higher degreewere obtained by determiningthe abscissas of intersection points of two monotonically increasing concave functions in the first quadrant of a planar rectangular coordinate system.

用高次方程正项分解方法，将求解实系数高次方程非零实数根的问题，转化成求解两单调上升凹函数在平面直角系第一象限内交点横坐标的等价问题；给出了基于共享存储多指令流多数据流并行计算模型求解任意实系数高次方程全部实数根的大范围收敛性异步并行迭代算法，并分析了算法计算的复杂程度。

Layer4: the transport layer The transport layer segments data from the sending host's system and reassembles the data into a data stream on the receiving host's system.

第四层：传输层传输层将发方主机系统送来的数据进行分段。并将数据重新组装成数据流送到收方主机系统上。

The monochrome mode bypasses these modules and basically serializes the data in FIFOH (and FIFOL if a dual scan display type is used) into 4-bit (or 8-bit if a 4-bit dual scan or 8-bit single scan display type is used) streams by shifting the video data to the LCD driver.

单色模式则不需要这些模块，基本上通过转换视频数据使 FIFOH(如果是双扫描显示类型则还有 FIFOL)的数据串行化为 4 位(若为 4 位双扫描或 8 位单扫描显示类型时为 8 位)数据流到 LCD 驱动器。

In the design of the system, emerged each function mold piece of the system detailed .

在系统分析中先后用数据流图、数据字典、系统的功能结构图分析了系统所需的各种数据。

Three horizontals are the representation layer, the operation layer and data layer.

首先，对软件需求做了深入的分析，通过数据流图和数据字典与用户进行沟通，了解用户对系统的功能要求等；其次，介绍了软件设计的过程，分为三纵三横，三纵即：概念结构设计、逻辑结构设计、物理设计三个阶段，三横即：表现层设计，业务层设计和数据层设计。

First, I have made thorough analysis to the software demand, carried on the communication through the Data Flow Diagram and the data dictionary with the users in order to get the system function request of users and so on. The next, I have introduced the process of software design, which is divided into three verticals and three horizontals. Three verticals are the concept structural design, the logical organization design and physical design. Three horizontals are the representation layer, the operation layer and data layer.

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
