电离层, 大气中的电离层
a layer in the upper atmosphere containing ions and free electrons, affecting radio communication and contributing to auroras
- The ionosphere reflects radio waves, allowing long-distance communication by bouncing signals off this atmospheric layer.
电离层反射无线电波，通过从这一大气层反弹信号实现远距离通信。
- The ionosphere is crucial for the operation of the Global Positioning System (GPS), aiding accurate location determination.
电离层对于全球定位系统（GPS）的运行至关重要，有助于准确定位。
- Radio signals passing through the ionosphere experience changes in propagation due to the presence of ions and free electrons.
穿过电离层的无线电信号由于离子和自由电子的存在而经历传播变化。
- The ionosphere's density varies with altitude and time, affecting the behavior of electromagnetic waves passing through it.
电离层的密度随高度和时间变化，影响穿过它的电磁波的行为。
- Auroras, like the Northern Lights, are produced when charged particles from the Sun interact with the ionosphere.
极光，如北极光，是当来自太阳的带电粒子与电离层相互作用时产生的。
