With Internet for representative of the information revolution, the society has entered the new network ages, the development of each realm of social economic and culture presents the all new mode." The numeral turns the campus" is an development mode and direction of each high school currently. In the construction of numerical campus application supporting system, the virtual laboratory of network is an important constituting part. As a kind of new teaching modes of experiment, the virtual laboratory is an outcome of the information ages, and it has the vast applied foreground in the realm of education and research, it is a new development direction of the experiment teaching. The development of the long range virtual laboratory system can overcome the shortage of the quantity and quality of the experiment instrument and the limit of experiment place and lesson number, and it can make full use of the instrument resources and make limited funds exert larger function. Therefore, the development of the virtual laboratory of network is very necessary. This text mainly introduced concept, characteristics and functions of the virtual laboratory, and it analyzed the key technique of carrying out the long range virtual laboratory, and it introduced the structure of software and hardware of the laboratory, and to take the dynamic state contingency test instrument as an example, carry on the research towards the project of setting up the long range virtual laboratory system.In addition,it introduced the establishment of the dynamic state contingency test instrument detailedly, make network of the virtual instrument come to truth.Finally,it carried on the detailed design and realizations of the long range virtual laboratory system according to the conjecture instrument. |
