LabVIEW~(TM) 7 express-based virtual instrument for measuring the surface tensions of solution

This paper introduces the Virtual Instrument for measuring the surface tension of solution by using LabVIEWTM 7 express language here.The VI can acquire real-time data,draw σ-c curve automatically,get the equation of σ-c curve and important parameters of the physical chemistry.When the VI applies on measuring the surface tension of solution,the experiment shows that the VI has the friendly interface,we can control it easily and extend it's functions freely.Using the library of VI's function,we can process the acquiring data deeply .The VI avoids the boring things and mistakes by human error at the same time it improves the veracity and recurrence greatly.
