大气折射 meaning in English
astronomical refraction
astrononmical refraction
atmo hericrefraction
atmospheric refraction
Examples
- A method of data correction of atmospheric refractive index
一种大气折射数据修正方法 - Discussion on the influence of atmosphere refraction to height - surveying and angle - surveying
测角受大气折射影响的讨论 - Research on starlight atmospheric refraction model in autonomous satellite navigation
卫星自主导航中星光大气折射模型的研究方法 - This means that the dielectric property changes with height and allows a slight increase in the speed of a radio wave as we move upwards through the atmosphere . this in turn means that if a radio wave moves away from the earth at an angle less than 90 degrees , then the upper part of the wave travels faster than the lower part . therefore even under normal conditions this can in effect bend , or refract , the wave back down to earth
其中一种显著的现象是：在一定的气象条件下，在大气边界层尤其是在近地层中传播的电磁波，受大气折射的影响，其传播轨迹弯向地面，当曲率超过地球表面曲率时，电磁波会部分地被陷获在一定厚度的大气薄层内，就好像电磁波在金属波导管中传播一样，称为大气波导传播，形成波导传播的大气薄层称为大气波导层。
