摘　　要：测量空气折射率时改变管内气体的状态多为抽气法,要想接近真空的状态,很不容易;本文介绍一种采用充气的方法代替抽气法的新测量仪器,操作方便,计算方法也不困难。Pumping is often used to change the state of gas in the tube when measuring the refractive index of air,but it＇s not easy to approach vacuum. A new measuring instrument for air refractive index is to be introduced in this paper, which adopts gas charge instead of pumping,offerlng more convenient operation and easier way for calculation.
