First the paper introduces thedevelopment and application about distance education inbfie￡also discusses produce and research of thenecessity and significance according to theckcumstances oflab are ,the conceptions ofvirtualinstrumenttechnology,the function of virtual laband the application environment withLabVIEW are virtualelectronic labisbuilt by thegeneral method ofthevirtuallab solution policy isdescribed by analyzing paring of several relativetechnology and software Browser/Server isadopted work construction and the Remote Panelstechnology is used authentication,filteringtechnology andtimely controlling technology锄used to work system includes virtual instrument and virtual integratedexperimental environment is implemented bining both simulation experiments and distance conduct virtuallab enables nsers to access and conduct experiments via Interact诵也just astandard web virtualinstruments are implemented including virtualsignalgenerator,virtual oscilloscopeand thefrequency characteristic measuring instrarnent onmeasurement andanalysis work ability,andthey plishes remote controlling andsharing by basic construct ofthe virtualelectronic lab based on Interact has done,and pleted some basicexploring which thesystem will beexpanded totheexperiment teaching on other oursesand other puter worktechnology
