Based on the analysis of the features of virtual design, such as the combinations of quantitative design and qualitative design, parallel and serial design, green manufacturing-oriented design, the closed loop architecture of virtual design system, including the iterative steps of converse engineering and digital modeling, physical prototyping, physical testing, is proposed.

本文在分析机械产品虚拟设计定性与定量相结合、串行与并行相结合、面向绿色制造的设计等主要特征的基础上，构造了一个包含反求工程与数字化建模、物理原型、物理测试等环节在内的机械产品虚拟设计可迭代框架，并以鼠标外模的虚拟设计过程为例对这一框架进行了详细说明。

The investment fictionalization and the fictitious investment are inevitableoutcomes of the development of market economy, so during we establish the marketeconomy system, it has important realistic significance that utilizing fictitiousinvestment to promote economy development as well as paying attention to keepoverfull investment away.

第七章，虚拟投资在中国的实践和发展主要侧重对中国虚拟投资发展的分析，说明虚拟投资在中国的表现和特征，并根据分析提出初步的政策建议。

In the meantime, we also can change the status of the logic situations and describe the allying process and cooperative process. In addition, we represent the virtual enterprise ontology in the formal logic situation calculus and can define the core elements more accurately. It maintains the consistency and integrality of the ontology. Accordingly, the process model based on the ontology will have strong reusability, accessibility and consistency.

相应地，我们可通过逻辑情景演算这种形式化逻辑框架来表示虚拟企业本体论，以支持虚拟企业本体论中核心术语的更精确定义，维持其一致性和完整性；进而，构建于该本体论之上的虚拟企业过程模型就具有很强的重用性和可访问性，并能够保持建模过程的一致性。

To decompose prismoid subject into sweepable sub-volumes, the source vertices project into target surface and decompose target surface to many subdomains. The virtual surfaces are found by linking opposite vertices from source surface and target surface, finally cut volume to sub-volumes. It is also designed spheriform decomposition based on geometry character.

虚拟分解主要是通过将棱柱体的源曲面边界顶点映射到目标曲面，将目标曲面划分成和源曲面一一对应的区域，连接对应的顶点建立虚拟剖分曲面，利用虚拟曲面将复杂的几何体剖分成子几何体。

In the light of fictitious money levy can produce what kind of practical effect, cao Gonghui expresses, conduct of more fictitious money business will undertake through operation business, is not undertake outside its body, of course, this also asks its reduce the cost of fictitious money, trade in order to expand quantity.

针对虚拟货币征税会产生怎样的现实影响，曹红辉表示，更多的虚拟货币买卖行为将通过运营商进行，而不是在其体外进行，当然，这也要求其降低虚拟货币的成本，以扩大交易量。

Its necessary to find a quick, reliable and static flat for the virtual communication system in order to ensure the trueness and reality, so the structuring of the system flat is the last key technique.

要保证虚拟通信系统的逼真性和实时性，就要寻找一个快速、可靠、稳定的平台来实现整个虚拟通信系统，虚拟短波／超短波通信系统平台的构建是关键技术之三。

Ship virtual reality design is the application of virtual reality techniques in ship design, realizing two stratifications of virtuality. The first is making possible for the ship owner, designers, shipyard and ship classification society to participate in ship design steps to pre-experience the performance of production. Second, it can put the emphasis on manufacture system and carry out effective analysis on its feasibility.

船舶虚拟现实设计是虚拟现实技术在船舶设计中的应用，对船舶设计制造过程实现两个层次的虚拟：一是设计阶段使船东、设计所、船厂、船级社都能够参与，达到预先体验产品性能的目的；二是强调制造系统层次上对生产制造可行性进行有效分析。

Based on the virtual simulation environment of virtual prototype simulation analytical software ADAMS, the reliability based virtual experimental research was developed on the broadly applied crank - slider mechanism.
