摘　　要：用自行组建的M-Z干涉仪测量空气在不同压强下的折射率,得到恒定温度下折射率随压强变化的具体关系,并从理论上对空气折射率的成因进行了分析,较好地解释了实验结果.The refractive index of air is measured under different pressure using a self-established Mach-Zehnder interferometer, the relationship between refractive index and pressure change under constant temperature is obtained theoretically, the cause of refraction of light by air is analyzed and the experimental results are explained better.
