Depending on it, MCF5249 can operate andcontrol SL811HS.While designing the USB system software, we use the MetrowerksCodeWarrior IDE as the programming and debuging tool. Firstly, the USB busdriver is be realized, which can detect、recognize and setup the USB device,then, the Bulk-Only transport driver is builded base on USB Mass Storageclass specification.

在软件设计上，以Metrowerks 公司的CodeWarrior 为编译调试平台，进行软件编码和调试，并利用M5249C3 开发板上的BDM 口和计算机的并口相连，通过下载CodeWarrior 编译生成的。elf 文件到MCF5249 的SDRAM中对软件进行功能测试；采用模块化设计的思想，将USB 系统软件分为通用的USB 设备命令和特定的USB 设备类应用程序两部分，对各模块分别加以实现。

Using numerical simulation technology and method of orthogonal experiment design and single factor rotating optimization, this thesis makes a study of "lost core injection ", thus achieve the optimization of the parameters of molding process, to offer basic reference when developing production technology and mould of the plastics intake manifold. Based on the study of the status in quo and development trend of weight reduction on automobile, the application of plastics to automobile and intake manifold, then under the guidance of theory model and numerical simulation technology in the process of high polymer material, this thesis launches flowing main research work: First of all, on the basis of the three-dimensional model of the part and finite element net model, several designs of gating and running system are numerically simulated and analyzed via MPA of Moldflow.

本文在对当今汽车轻量化、零部件塑料化以及的汽车进气歧管塑料化的发展现状和发展趋势进行了研究和简要介绍，然后在高分子材料成型过程中的理论模型和数值计算方法的指导下，展开主要的研究工作：首先，在零件三维模型和有限元网格模型的基础上，使用Moldflow 的MPA模块对塑料进气歧管的多个浇注系统设计方案进行数值模拟，通过分析各个方案的充填质量、熔接线位置及数量等指标，得到了综合质量较高的4 个进料口的浇口位置及半限制型浇口大小的浇注系统。

To use it you will need a programmer board attached to your parallel or serial port.

要使用它，你需要将一个编程板连接到你的并口或串口上。

Eventually, the set-top box will have a USB port and you will upload the content from there.

将来机顶盒会有一个USB的端口，用户可以将内容通过这个端口上传。

Sense, it also reflects the shape curve extraordinary classically elegant conference, the most prominent feature is the 1.4 with one foot bathtubs bottom, like a giant flowerpots; Ramps and special mouth design, high-mouth part of it back to the bath, a very close sense; color than ordinary bathtubs rich easy choice, and wall and floor tiles in the area making it more flexible.

除了材料上的古旧感，它的造型曲线也体现了非凡的古雅柔美，最突出的特色就是浴缸底层的四角各有一只脚，就像个巨型花盆；而特殊的斜口设计，使浴缸高口部分便于靠背，十分具有亲近感；色彩上比普通浴缸丰富，便于选择，与墙砖和地砖的配合方面更显灵活。

The front vent windows now employ a chrome air deflector on the upper edge of the vent window frame and a gas filler door hides the open gas cap of the '49 Ford.

前面的通气口视窗现在使用在通气口窗囗的上边缘上的一个铬空气偏流器车架，而且一扇气热隔片门藏 1949 福特的未结清气插接帽。

The elevation 4860 meter Tanggula shankou, several "the sunspot" appears in silver world --- these shoulders shoulders the hard shovel, is lifting the hoisting jack worker, upward enters in the Qinghai and Xizang railroad Tanggula shankou section railway rail, looks like on the 5 lines several happy symbols.

海拔4860米的唐古拉山口，十几个&黑点&出现在银色的世界———这些肩扛铁锨、抬着千斤顶的工人，在青藏铁路唐古拉山口段的铁轨上行进，像五线谱上的几个乐符。

The main products of the sticks is die-cutting on automatic die-cutting machine requires will rely on a pipe of knife more force several narrow-necked, smooth production after the die cutting machine out, in the sense of narrow-necked reflected in the die-cutting on the box of the edge is not smooth.

影响产品美观的主要原因是在平压平自动模切机上进行模切加工时需要将靠叼口边的刀多敲破几个小口，才能顺利地将模切后的成品从机器中拉出来，敲破的小口体现在模切后的盒上是边缘不光滑。

The transmission fork and lug on each change-shaft is fastened by the spring pin (Q5280835) and

叉轴上的变速叉和导块均由波口弹性销(Q 5280835)和波口弹性销(Q5280535)固定。

In the computer chassis before and after the panels are left in USB interface, we should, if possible, mobile hard drive inserted into the chassis back panel USB port, after all, the back panel of the USB ports are integrated directly into the computer motherboard, this USB port are generally considered safe grounding design, we found the body of the static it becomes hard to move a threat to the safety of the hard disk USB interface.

在电脑机箱前后面板中都留有USB接口的情况下，我们应该尽量将移动硬盘插入到机箱背面板上的USB端口中，毕竟背面板上的的USB端口通常直接集成在计算机主板中，这种USB端口一般都有安全接地的设计考虑，所以我们人体身上的静电就不大容易威胁到移动硬盘USB接口的安全。
