摘　　要：介绍一种用于液体特性研究的新型仪器——光纤、电容液滴分析仪 (FCDA:Fiber- Capacitive Drop Analyzer)。该仪器利用光纤液滴分析技术和电容液滴分析技术制成特殊的液滴传感器 ,获取经过液滴的光强信号随液滴生长变化的规律 ,得到反映液体综合特性的“液滴指纹图”。通过对部分样品进行测试实验 ,证明液滴指纹图可以作为鉴别液体的依据 ,同时具有测量液体物理。An instrumental method for measuring the properties of liquids has been developed. The instrument, called the fiber capacitive drop analyzer (FCDA),is based on a specially designed drop sensor by means of the fiber drop analyzing technology and the capacitive drop analyzing technology,and produces a volume based fiber drop trace (VFDT),which shows the relation between the light intensity passing through the liquid drop and the instant drop volume. Preliminary experiments have been carried out and these prove that VFDT externalizes the overall properties of tested liquids and is suitable for fine discrimination among different kinds of liquids. VFDT is also potentially capable of simultaneously measuring the physical and chemical properties of liquids.
