III DESIGN AND REALIZATION OF A VIRTUAL LAB AND SENSOR VIRTUAL INSTRUMENTS BASED ON LABVIEW ABSTRACT At present, experimental resources in schools can not meet the needs of teaching, because of con tinued expansion in the gr ants. High requirements of experiments and hands-on ability in many professionals especially science and engineering professional is needed. A lthough the government has increased the school's funding of education and resear ch , both the quantity and quality of the school's laboratory equipments are not able to meet the actual demand when facing with so many students who need experiment. With the development of hardware and programming language puter, virtual instrument is produced. Exploiting and using the virt u
