“电离层折射与电波传播延迟”的概念、定义、翻译、参考文献-科学参考

单词	电离层折射与电波传播延迟
释义	电离层折射与电波传播延迟 Encyclopedia 理学电离层折射与电波传播延迟释 ionospheric refraction and radio wave propagation delay电离层折射与电波传播延迟海拔高度60公里左右以上的地球大气圈，是由自由电子、正离子、负离子、分子和原子组成的处于部分电离或完全电离的部分。电波穿过电离层的传播过程中，在传播路径上等离子体不同的密度的折射和色散本领不同，折射使得电波传播偏离行进方向，色散效应导致电磁波传播的相速度高于真空中传播速度、群速度低于真空中传播速度，引起传播的延迟效应。
