| 1. | Its upper limit is determined by the conditions in the ionosphere . 其上限由电离层的状态而决定。 |
| 2. | Rockets and artificial satellites can go far above the ionosphere . 火箭和人造卫星能够到达电离层以上极远的地方。 |
| 3. | Their main limitation is that they are incapable of rising to the ionosphere . 他们主要局限性是不能上升到电离层。 |
| 4. | The ionosphere is that region of space containing electrically charged species . 电离层是指含有带电物质的空间区域。 |
| 5. | The ability of the ionosphere to reflect these waves is dependent upon normal variations in the electron density at different levels . 电离层反射电波的能力取决于不同高度上电子密度的正常差别。 |
