By rational designs of mechanical structure and plan, the system uses PLC as the core of control on site, and accomplishes control of the installment and debug of the system step by step by software configuring design of the touch panel. Industrial computer, the centre of monitor, control and management of the system, composes epigyny and hypogyny machines' real-time monitoring and controlling system with PLC by designing the communicative model and program, and accomplishes man-machine dialogue in form of suppositional panel by designing supervisory software. Meanwhile, we also adopt client/server model and realize long-distance supervision of impact sensitivity experiment by program designing.

系统通过合理的机械结构和方案设计，采用PLC作为现场控制核心，通过对触摸屏软件组态设计，完成了系统现场安装、调试时的单步控制功能；作为系统的监控、调度中心的工控微机通过通讯模式和程序设计，与PLC组成上、下位机实时监控系统，间接地实现了对撞击感度试验的监控，并通过上位机实时监控管理软件的设计，以虚拟面板的形式较好地实现了人机对话；采用客户机／服务器模式，通过软件编程实现了撞击感度试验的远程监控功能。

Using virtual prototype technology to study high temperature rotation scanning target in this paper, it not only obtained a certain achievement, but also laid the foundation for applying virtual field technology in other key parts even and all of the high-current oxygen ion implanter.

本文应用虚拟样机技术来研究高温旋转扫描靶，取得了一定的成果，为今后将虚拟样机技术推广到强流氧离子注入机其它关键部件乃至整机的研究奠定了基础。

ABSTRACT Virtual Coordinate Measuring Machine is proposed against Virtual Manufacturing and Virtual Reality, its basis is Virtual Re...

This mechanism makes the microinstruction execute orderly. Compared with the other model computer of virtual lab, the universality, autonomy and reusability of CPU_VLAB increase, and CPU_VLAB is interactive. In addition, the trigger-dispatching mechanism of CPU_VLAB provides references for developing virtual lab of computer hardware courses.

与已有的模型机虚拟实验平台相比，该实验平台不仅在通用性、自主性和可重用性等方面有较大的提高，而且具有良好的可交互性，同时，CPU_VLAB的组件调度机制为开发计算机硬件类课程虚拟实验平台提供参考。

Spooling and a file system can provide virtual card readers and virtual line printers.

Spooling 与档案系统可以提供虚拟的读卡机和虚拟的列印机。

The coming forth of virtual prototyping technology presents a new approach to study gun stability, and based on establishment of dynamic model of selections of structure parameters, the effects of stiffness and damper of elevating mechanism, stiffness and damper of trail, stiffness and damper of soil, parity of recoil mass and parity of trunnion position on firing stability are first studied with virtual prototype of gun in this paper. An improved equation of sensitivity analysis is provided, and the important degrees of factors with different dimensions can be compared.

虚拟样机技术的出现为火炮射击稳定性研究提供了新的方法，文中在建立火炮动力学模型的基础上，通过选取火炮结构参数对火炮射击稳定性进行研究，利用虚拟样机分析高低机刚度和阻尼、大架刚度和阻尼、土壤介质刚度和阻尼、后坐品质偏心和耳轴位置偏心对火炮射击稳定性的影响。

From the view points of informatics, the process of cognition is a series of receiving managing ,outputting and back-feeding activies in deed. Such dynamic process is called "cognitive pattern" presupported by the intellect as living intent, do cognitive pattern has evoluted into "Human-computer" model.Secondly, informationization has made social activies more efficient. The consciousness of making full use of information has become on unintegrated part of the whole social ideology. It absolutely exerts active impacts on social activies. Especially the virtual technology comes into being and becomes mature.

按照信息论的观点，人的认识机制实质上是获取、加工处理、输出并反馈等一系列信息的运动过程，形成所谓信息的反映论模式；计算机网络日益智能化的前提下，认识模式逐渐演变成"人—机"为认识主体的新认识模式；其次，信息化社会随着信息实践活动的日益增强，信息意识作为社会意识的一个方面，对社会实践起着积极的作用；计算机虚拟技术的出现与逐渐成熟，开创了人类实践的新境界——虚拟实践。

It was composed of four parts,named control center,physical tester,virtual tester,and remote observer.

该平台由控制中心、真实试验机、虚拟试验机和远程观察器4个模块组成，各模块由计算机网络连接在一起，采用并行通讯模式实现控制中心与试验机和观察器之间的数据传输。

When an order is form in position machine, the needed breeds and quantity of cigarette will be established and thesequence and time of cigarette sorting in an order will be also established, so before sorting an order, the order'length can be compute, but before sorting an order, the order's space is existenced as a virtual space, thus supposed a virtual space which loaded finished cigarette and order when virtual space arrive the corresponding sorter, plc control the time parameter and activated the sorting, and the sorter sorting cigarette to virtual space, an order accomplished.

对件烟行走时间进行了建模并提出了一种烟草自动分拣算法，当订单在上位机生成后，所需烟品种及数量随之确定，因此订单中所要分拣的烟分拣的次序及分拣的时刻也就可以确定，所以在订单分拣之前，订单的长度是可以计算出来的，而在未真正分拣之前，订单的长度是一个&虚拟存在的空间&，应用逆向推理的过程可假设一个装成品烟和订单的&虚拟空间&，当&虚拟空间&到达对应的分拣机位置时，通过plc对订单中件烟时间参数的控制，分拣机自动分拣件烟至&虚拟空间&完成订单分拣，该算法实现方便并能节约大量的硬件成本，对其他一些物流分拣行业也具有一定的推广价值。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
