论文摘要
Gladstone-dale的经验定律不足以使用气体的折射率进行高精度研究：这与其密度不成比例，并且气体可能无法正确描述为完美。光学玛丽奥特温度允许对各种作者给出的结果进行比较分析。从历史上看，湿度法对可见波长的折射率的影响是对天文折射角的数值所示的小小的。最后，在红外和无线电波长下，较低大气中湿度的影响可能很强。至于电离层，与可见的不同，其曲率对于天文折射角起着至关重要的作用。
The empirical law of Gladstone-Dale is insufficient for high-precision studies using the refractivity of a gas: this is not exactly proportional to its density, and the gas may not be properly described as perfect. An optical Mariotte temperature allows making a comparative analysis of the results given by various authors. The effect of hygrometry on the refractivity at visible wavelengths is historically traced and its small effect on the astronomical refraction angle numerically shown. Finally at infrared and radio wavelengths, the effects of the humidity in the lower atmosphere can be strong; as for the ionosphere, its curvature plays an essential role for the astronomical refraction angle unlike in the visible.
