Design and Implement of Network Virtual Laboratory

The traditional way of physical instruments and simple data analysis is still used for experimental teachings in the most domestic colleges and universities.It exists many problems.A network-based virtual laboratory framework model was established with the network technology,virtual instrument technology and B/S architecture.A related virtual experiment such as phase difference measurement was designed,and Web publishing was implemented by means of LabVIEW software.Practice shows that the remote control and resource sharing can be achieved in the Web-based virtual laboratory.It can save the financing investment for the mass of equipments and instruments,provide a modern means for practice teaching,and help students to improve their creative ability.
