Experimental technique is the use of virtual software and the combination of computer hardware to replace the traditional conventional test equipment, computer networks or computer simulation of various experimental techniques. LabVIEW is widely used development tools, virtual experiment apparatus, the use of LabVIEW development platform for the preparation of the process is called virtual instrument procedures, referred to as VI. The use of LabVIEW software, we can easily develop a variety of virtual instrument procedures, they can run on a computer to simulate the effect of actual use of equipment. Mechanical Engineering Mechanical Engineering control of basic courses are part of a series of experiments to consolidate the understanding about the content of the classroom at the same time, the classroom in some places on the need to demonstrate a number of demonstration experiment, if for different input signal, a second-order system response curve. This paper describes the development of demonstration of the use of LabVIEW to control the basis of mechanical engineering courses in a typical second-order system signals (unit impulse, unit step) in response to the production of virtual machines can be used to demonstrate the actual effect of the experimental use of the classroom or after school.

1.为现代化教学终端设备提供互动教学软件。随着学校条件的不断改善,不少教师配备了液晶电视、交互式白板、甚至开始了一对一的电子化学习。虚拟实验软件创建了一个让学生自主进行实验器材组装,实时观察实验现象并做出实验结论的学习方式。例如《原电池实验》2.弥补因实验器材不足、仪器贵重或易损造成很多实验无法开展的问题。在传统实验教学中,有时存在很多客观因素造成实验无法进行,例如许多昂贵的实验器材,由于受价格的限制而无法普及;有些实验因时间持续得很长以致无法开设等。学校很难有条件或提供足够多的时间让学生对贵重仪器进行操作学习。利用虚拟现实技术,在多媒体计算机上建立虚拟实验室,学习者便可以身临其境般地操作虚拟仪器,操作结果可以通过仪表显示反馈给学生。这种实验既不消耗器材,也不受场地等外界条件限制,可重复操作,直至得出满意结果,改变了传统演示实验的教学模式,有效地解决了实验条件与实验效果之间的矛盾。3.让学生安全地模仿真操作具有危险性的实验。在中小学一些教学实验,例如化学实验会用到一些危险的实验器材;药物制剂实验中有很多涉及到放射性物质或有毒物质的部分,有些实验是不能让学生做的。可以通过让学生先进行仿真操作再进行实际操作,可以杜绝事故的发生,还大大提高了实验的效率。例如《一氧化碳还原氧化铜》实验中如果试管中的一氧化碳不纯净,加热后会发生爆炸。4.激发学生实验操作的兴趣,将抽象的概念形象化。虚拟实验软件可以激发学生实验操作的兴趣,弥补实际实验教学的一些不足,将抽象的概念形象化,让学生认清概念的本质。例如小学科学课程中《种子发芽》实验,在实际操作中这类实验需要花费很长的周期才能完成,很难将学生的学习兴趣保持下去。

虚拟实验在英语教学教学中应用有:初步基本的实验知识,可以在虚拟实验中练习,虚拟实际上是计算机模拟。虚拟实验是指借助于多媒体、仿真和虚拟现实(又称VR)等技术在计算机上营造可辅助、部分替代甚至全部替代传统实验各操作环节的相关软硬件操作环境,实验者可以像在真实的环境中一样完成各种实验项目,所取得的实验效果等价于甚至优于在真实环境中所取得的效果。虚拟实验建立在一个虚拟的实验环境(平台仿真)之上,而注重的是实验操作的交互性和实验结果的仿真性。虚拟实验实验有称为电子实验,和动态体验,虚拟实验的效果就在与能与现实结合,通过实验来确定生活中是不是想能完成现在的实验现象。虚拟实验室是一种基于Web3d技术、虚拟现实平台(如VR-Platform) 构建的开放式网络化的虚拟实验教学系统,是现有各种教学实验室的数字化和虚拟化。虚拟实验室由虚拟实验台、虚拟器材库和开放式实验室管理系统组成。虚拟实验室为开设各种虚拟实验课程提供了全新的教学环境。虚拟实验台与真实实验台类似,可供学生自己动手配置、连接、调节和使用实验仪器设备。教师利用虚拟器材库中的器材自由搭建任意合理的典型实验,或实验案例,这一点是虚拟实验室有别于一般实验教学课件的重要特征。虚拟实验室也是一种能在现实中体会到的实验,实验的体现使人们对太空有了更深刻的了解。
