2、的学校集中完成实验项目.技能培养质量无法保证。教育机构必须考虑如何跟上实验的时代性和先进性，创设实验内容丰富、训练操作扎实、不受时空限制的开放性实验环境。近年来，由于虚拟仪器、仿真技术和网络技术的飞速发展，构建基于LabVIEW的虚拟网络实验室将会成为一种经济、高效的首选方案。本文的主要工作就是在LabVIEW环境下，研究基于虚拟仪器的网络教学实验系统的设计问题。首先，本文对虚拟仪器进行概述，对比了与传统仪器的区别，介绍了虚拟仪器的软件开发平台LabVIEW的应用，以及在LabVIEW环境下进行几种常用虚拟仪器虚拟信号发生器、相关分析、滤波器、和虚拟频谱分析仪等的软件设计方法。接着，本文着重介
3、绍了如何把设计的几种虚拟仪器构成一个虚拟实验室，并利用虚拟仪器技术创建一个网络虚拟实验室，充分运用网络技术构建一个网络虚拟实验系统，并采用虚拟仪器的网络通信技术实现该网络虚拟系统的远程实验目标。本课题研究可以节省许多基础设施的重复建设和仪器设备重复引进的资金投入，有利于从整体上改善办学条件和提高教学水平。在很大程度上方便了学生，不仅能够引导学生理解实验的理论知识，而且能够指导学生进行正确的实验操作，从而获得感性上和理性上的认识。虚拟实验室不仅极大的弥补了远程教育模式的局限和不足，而且还使得远程教育的方式方法更趋完美。将虚拟实验室与远程教育结合在一起，基于网络技术和虚拟仪器技术的虚拟实验室己成为
