【Abstract】 Fiber-Capacitive Drop Analyzer(FCDA), a newly developed instrument to study the property of the liquid, 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. The instrument has the capability to measure the parameters of the physical properties of the liquid. This paper shows the study on the measurement of the refractive index of the liquid by FCDA. It shows the measurement result of the refractive index of alcohol of different consistence and the error analysis.更多还原
