摘要: 设计了一种能够精确测定密闭容器中饱和酒精气体折射率的实验装置。该实验装置利用干涉法观察密闭容器中饱和酒精气体压强变化前后干涉条纹变化情况,结合推导出的干涉条纹变化数与饱和酒精气体折射率的关系,测量该饱和酒精气体在一定压强下的折射率。结果表明,干涉法测密闭容器中饱和酒精气体的折射率理论推导严密,测量方法及原理简单,测量结果可靠。此方法可以推广到气体折射率的测量,尤其可以应用于大容量油品储蓄罐的液位测量中。

Abstract:

A method for measuring the refractivity of saturated alcohol gas in high precision in closed vessel had been designed. This experimental apparatus used an interference method to observe the variation of interference fringes when the gas pressure changed, combining with the relationship of the number of the changing interference fringes and the refractivity of saturated alcohol gas, then the refractivity of alcohol gas under a certain pressure could be measured. The results showed that this method was accurate in deduce, simple in measurement and method, and reliable. This method could be promoted to measure the refractivity of gas. Especially, it also could be used to measure the liquid level of the liquid-storage tanks.

Key words: Interference method, Alcohol gas, Refractivity, Atmosphere pressure, Interference fringe
