计算机系统

For solve problem these, we basis these design one computer lab fire prevention the burglary-resisting system, computer lab fire prevention burglary-resisting system through infrared sensor , temperature sensor , gas detector has lenses, spend the system lasting 24 hours to control to the computer lab to transmit to the picture , find unusual situation autoalarm , play a firing prevention theft- proofly role really , can make computer system relatively safe in one, in the reliable environment , operate steadily for a long time , and lengthen service life as much as possible .

为了解决这些问题，我们依据这些设计了一套机房防火防盗系统，机房防火防盗系统通过红外传感器，温度传感器，气体探测器还有摄像头，利用系统对图像传输对机房实施二十四小时监控，发现异常情况自动报警，真正起到防火防盗作用，能够使计算机系统在一个相对安全，可靠的环境里，长时间稳定地运转，并尽可能延长使用寿命。

This text describes the basie train of thought and the basie method of the reform of the computer hardware teaching of computer science and technology speciality in Chinese normai universities from the angle of the social develop-ment in the 21 st century.

1引言 计算机系统是由硬件系统和软件系统构成的，硬件系统和软件系统既相对独立又相互作用，相辅相成，构成一个完整的系统，并且缺一不可。

The dissertation begins a deep discussion of the main parameters which may affect the performance of dynamic binary translation and optimization system, and proposes the annotation directed binary translation and optimization, which combines the static compilation and dynamic compilation to improve the performance of the binary running on the computer system.

首先，本文在深入探讨了动态二进制翻译系统中影响性能的主要因素的基础上，提出了注解信息制导的翻译及优化方法，来结合传统编译器和动态二进制翻译和优化系统以提高二进制代码在计算机系统上的运行性能。

So we give a new colligate computer system to solve the problem.

ABSTRACT Redundancy management plays an important roll in fault-tolerant computer system.

冗余管理在容错计算机系统中占有相当重要的地位，其目的是在系统出错时保持系统处理的完整性，并阻止系统错误输出。

After the persistent practice in the 1990s, using open system idea to integrate large scale computer systems has been the consentient fact In order to embody high efficiency and intelligent collaboration in open systems, core architecture, called common agent request broker architecture, is established based on mobile agent, and agent based computing basic architecture is constructed based on CARBA Structure of CARBA and ABCBA, domain interface of ABCBA, extension of ABCBA in nomadic environment, and relation among ABCBA OMA, and ODP are discussed in detail Experiment results are given, which show that it is feasible to use ABCBA to improve efficiency and collaboration in open systems and ABCBA is suitable in both wired and wireless network environment

经历 2 0世纪 90年代的持续实践，采用&开放系统&的思想来集成大型的计算机系统已成为技术界不争的事实为了使得开放系统体现实时性和智能协作性，以移动agent为基础，建立了&公共agent请求代理体系结构&，并以CARBA为核心形成了&基于agent的计算基本框架&阐述了CARBA及ABCBA的基本结构、ABCBA领域接口、ABCBA在移动领域中的扩展、ABCBA与OMA及ODP的关系，并给出了实验结论表明：利用ABCBA来提高开放系统协作性和效率是切实可行的，所形成的ABCBA框架在有线、无线环境中都是适用的

The first and the second chapters will discuss the significance of reseach, and system plan of the Marine SHARS, including the design of system function, the selection of inertial devices and design of system function, and A/D convertors and the construction of hardwares and softwares of the Marine SHARS.

第一部分讨论了舰载捷联式航向姿态基准系统的选题意义、系统总体方案的设计思想，其中包括系统功能的方案设计、惯性仪表和模/数转换电路的选择、导航计算机系统硬件和软件的方案设计等。

I also thought that the beginning of the phenomenon of the failure was due to display card driver caused the destruction, so I right-click the desktop system, the "My Computer" icon on the shortcut menu from the pop-up the implementation of "property "command, open the System Properties settings window, click the window of the" hardware "tab, and in the corresponding tab page, click" Device Manager "button, open the device list window, use the mouse to start the window "Show card" option, and then double-click the mouse "standard VGA graphics adapter" project, open the corresponding project page the driver tab, click the tab page in the "Uninstall" button to display the current card driver procedure removed, and then restart the computer system, then let the system automatically re-installed the graphics card driver.

开始阶段笔者还以为该故障现象是由于显示卡驱动程序遭到破坏引起的，于是笔者用鼠标右键单击系统桌面中的&我的电脑&图标，从弹出的快捷菜单中执行&属性&命令，打开系统的属性设置窗口，单击该窗口中的&硬件&标签，并在对应的标签页面中单击&设备管理器&按钮，打开系统的设备列表窗口，用鼠标展开该窗口中的&显示卡&选项，再用鼠标双击&标准 VGA 图形适配器&项目，打开对应项目的驱动程序标签页面，单击该标签页面中的&卸载&按钮，来将当前的显示卡驱动程序删除掉，之后将计算机系统重新启动了一下，同时让系统自动重新安装了显示卡驱动程序。

Systems, which control scientific experiments, medical computer systems, industrial control systems, and some display systems are real-time systems.

控制科学实验的系统，医学计算机系统，工业控制系统以及一些显示系统都是实时系统。
