摘要
液体的折射率和液体的密度有直接关系,液体密度又与温度有关,根据已有关于透明介质的折射率公式,可得液体的膨胀系数的测量方法.迈克耳孙干涉法是测量液体折射率的温度系数的简捷的手段.用此方法得出了液体的膨胀系数,进而讨论了关于液体折射率的2个不同公式的精确程度.
The refractive index of liquid is related to the density of liquid, the density of liquid is related to thetemperature of liquid based on a general refractive index equation of transparent material. It is easy for measuring the temperature dependence of the refractive index of liquid by using optical interference. The thermal expansion coefficient of liquid is obtained and the formulas of refractive index of liquid is discussed.
