High resolution radio refractive index studies in India using airborne microwave refractometers

We discuss high resolution measurements on radio refractive index, in the boundary layer and above the atmosphere in the Indian sub-continent spread over a period of more than a solar cycle by making use of airborne microwave refractometers, operating around 9 GHz. Some atmospheric turbulence parameters comparable with earlier results have also been derived. The results demonstrate sharp gradients of radio refractive index, layer structures and the variability of the boundary layer in time and space. An erratum to this article is available at .     

宝石折射仪测试结果的计算机模拟与分析

本文在分析了宝石折射仪原理的基础上,提出可以用光率体在垂直于折射仪长轴方向的椭圆切面来判断所测宝石折射率的大小。据此原理,建立了分析折射仪测试结果的数学模型,用计算机模拟出了可能存在的30种折射率曲线型式。并对这些曲线型式的特点进行了分析。
