摘　　要：设计开发了基于LabVIEWTM 7 Express测定溶液表面张力虚拟仪器系统。实现了实验数据的实时采集、动态显示、自动绘制σ-c曲线和获得曲线方程,同时可得到,等重要的表面化学参数。实验表明:利用LabVIEW开发测定液体表面张力的虚拟仪器,编程直观高效,仪器面板友好、易操作、功能易扩展,还可利用LabVIEW自身所带的软件包对实验数据进行实时处理, 避免了人工数据记录、处理、绘图的烦琐和人为误差,提高了实验结果的准确性和重现性。This paper introduces the Virtual Instrument for measuring the surface tension of solution by using LabVIEW^TM 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.
