摘　　要：E-learning系统作为传统实验教学的有力补充,提供了一条有效的途径来解决实验教学软硬件的制约问题,不仅可以逼真地展现实验,而且可以提高实验教学的效率。虚拟装配(Virtual Assembly,VA)技术,是主要应用在工业制造领域中的数字化技术,在工业产品的设计、生产、评估阶段,能够有效提高制造效率和质量,节约成本,缩短产品制造周期。但在不同阶段,虚拟装配技术可以有不同的特点。将虚拟装配技术集成到E-learning系统中,可以帮助学生学习和理解科学实验中仪器的功能和操作。针对E-learning系统要求的特点,可以改进工业中使用的虚拟装配过程。在系统中的虚拟装配,有两个特点:不需要精确的三维模型的约束条件;几乎可以接受所有类型的三维模型。因此,该虚拟装配对于各种领域E-learning的发展和扩展是非常有用的。E-learning system as a powerful complement to traditional experimental teaching, provide an effective way to solve the constraints in experimental teaching software and hardware. The system can simulate the experiments realistically and improve the efficiency of experimental teaching. Virtual Assembly （VA） technology, a digital technology which is mainly used in industrial manufacturing field, can promote efficiency and quality and save cost, shortening the manufacturing cycle in the design, production and assessment phase in commercial manufacture. But at different stages, virtual assembly technology can have different characteristics. The virtual assembly technology into E-learning system can help students learn and understand the function and operation of scientific experiments instrument. Improve the virtual assembly process in industry according to the features of E-leaming system. The virtual assembly used in the system has two features, which does not need the precise constraint relationships of 3D models, and can accept almost all the 3D model formats. Therefore, this virtual assembly is very useful for fast development and easy to be extended to various science E-learning areas.
