Studing And Designing Of Algorithm For The Instruments Of The Virtual Laboratory

As the increasing informationazation of all the society,the modern schooling is inevitably affected by the"information explosion".The teaching and learning resources are not monotonous as they used to be,and not stricted by the horizons of knowledge of teachers,they are appearing to a massive growth and a rich and colorful complexion.With the Virtual Reality Technology being widely used,the contribution of the virtual laboratory is to be the overriding concerns by the professional visitors.The relevant issueses ,which are about virtual instruments that are essential for virtual laboratory, are to be studied in this paper. A scheme of virtual instruments Component library construction is brought forward for programmers ,provides an abstract instrument library and an operating entity in programming.Firstly Starts from the classification of the instruments,discuss the classification strategies; Study the logical relations between instruments like association and compound,or the certain relations of instruments in the process of experiments;Study the changing status of instruments in different experiments,how are the process of experiments unfolded with the status changing from one to another;the models of the virtual instruments are analysised and designed;construct the architecture of the component library; The repeatedly development strategy based on the component library is to be studied.
