In this paper, the concept, connotaion, characteristic, class and key technologies of virtual manufacturing are introduced.

介绍了虚拟制造的基本概念、内涵、特征、分类和关键技术，着重阐述了虚拟制造技术在国内外电子工业领域的应用和取得的成果，并探讨了电子虚拟制造技术应用的进一步设想和发展趋势。

The development of modern skin flap chirurgery needs badly the three- dimension picture system to display the blood supply and other profound structures and functions. This kind of system can also support the clinical training, designing of operative route, suppositional operation procedure and fidelity navigation during the operation. 3D imaging studies such as computed tomography and magnetic resonance provide the primary source of patient-specific data for such medical applications. The two-dimensional (2D) images produced by CT and MR imaging techniques represent a series of cross-sectional image slices through ones anatomy.

现代皮瓣外科学的发展迫切需要显示其血供等复杂结构和功能的三维图像系统，为临床医生的培训、手术入路的设计、手术过程的虚拟和术中的精确导航提供支持，同时随着人体标本来源的日趋减少，有必要建立一整套包括常用皮瓣、肌瓣和骨瓣在内的三维解剖以供骨科临床教学和训练所用，随着"虚拟人"、计算机虚拟技术和现代医学影像技术的快速发展，使得虚拟皮瓣外科手术的研究与应用成为可能。

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.
