This makes the point to point intervisibility testing algorithm more real and efficient and gives the environmental information to the dynamic entity in the large scale virtual environment more efficiently.

利用虚拟现实技术，可以将真实世界加以抽象和模型化并转换为计算机系统中的虚拟世界，用户通过交互设备可以与虚拟世界中的各个实体进行交互，从而产生与真实世界相似的感觉和体验。

Next, although duty Wu branch has authority to collect fictitious money,trade duty, but as a result of at present on the net fictitious trading is individual behavior mostly, many and small trade fragmentarily finishing under the counter, below the circumstance that did not execute network real name to make, superintend trade under the counter difficulty will be quite great, tax authority also very will difficult differentiate after all those trade attribute action of fictitious money business.

其次，即使税务部门有权征收虚拟货币交易税，但由于目前网上虚拟交易大多都是个人行为，大量小额零星的交易都在私下完成，在没有实行网络实名制的情况下，监管私下交易难度会相当大，税务机关也将很难判别究竟那些交易属于虚拟货币买卖行为。

The paper introduced Virtual Reality synoptically at first. It expatiated on thebasic factors and characters of the VR system. It expounded the hardware andsoftware realizations of VR also.

本文首先对虚拟现实技术进行了概括性介绍，阐述了虚拟现实系统的基本要素、基本特征以及虚拟现实的硬件实现和软件实现。

The original purpose of a virtual device driver in Windows 3.0 was to virtualize a specific device in order to help the VMM create the fiction that each virtual machine has a full complement of hardware.

在Windows3.0里一个虚拟设备驱动的最初目的本来是虚拟一个特殊设备来帮助VMM创建一个函数，每个虚拟机具有一个硬件的全部功能。

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。

The Virtual Experiment and Virtual Laboratory appear with the development of computer technique and Virtual Instrument technique.

摘要虚拟实验与虚拟实验室是随着计算机技术、虚拟仪器技术的发展而出现的。

The main contents and results of research in this paper are shown as following: It is important to built the motion model of a virtual system. As the virtual object is the submarine in this simulation system, we studied on the motion model of the submarine and gave the submarine six DOF space motion equation MultiGen-Paradigm corporation's modeling software named Creator is used, the modeling of all entities and 3D terrain in virtual ocean environment is accomplished. Then introduced the theory of Large Area Database Management and realized the Large area database management; In the course of 3D scene simulation, Vega is utilized to develop the project. The building of 3D scene is done, which includes the simulation of static and dynamic ocean surface, realization of ocean wave, simulation of bow wave and stern wake, utilization of lighting and material, simulation of cloud and fog, kinematics' modeling of submarine etc.

论文的主要研究工作和成果包括以下一些内容：建立虚拟对象的运动模型是构造一个虚拟系统的关键所在，建立的运动模型准确与否直接关系仿真对象模拟的逼真度，由于本仿真系统的虚拟对象是潜艇，所以对潜艇的运动模型进行了研究，给出潜艇空间六自由度运动方程；利用MultiGen-Paradigm公司的Creator建模软件完成虚拟海洋环境中个实体模型建模和三维海底地形模型的建模；然后介绍了大地形数据库管理(LADBM，Large Area Database Management)技术的基本原理，实现大地形数据库管理；在三维场景仿真中，使用Vega驱动软件进行软件开发，完成了三维场景空间的建立，主要包括动态和静态海洋的仿真、海浪、船首波浪和传尾尾迹的实现，灯光和材质的使用，云和雾的模拟等。
