| 摘 要： | 电离层从猜想到证实完全是无线电技术发展的结果。通过地面无线电探测和火箭、卫星的空间探测、证实了Ｃｈａｐｍａｎ的理论。由于太阳紫外线，Ｘ射线辐射致使高空上层大气电离。电离层介质是电子、正负离子和中性粒子全体的混合物。它们构成了地磁场中磁离子介质。本文根据磁离子理论，研究了电离层中等离子体的频率特性，从而解释了Ｄ、Ｅ、Ｆ１和Ｆ２层的电波反射特性。最后计算了陕西天文台至云南天文台电离层波导的传播时延，获得了有意义的结果。

| Abstract: | The Ionosphere from the supposition to the confirmation was resulted edtirely from the development of the radio technique.The chapman's ionosphere theory had already been confirmed by the surveyes of the radio waves on ground-based and of the rockets and satellites in space.The atmosphere in the high layer are ionized by the solar UV and X-ray.The ionospheric medium is a mixture of electrons,positive ions,negative ions and neutral particles,which form the magnetic-ion medium.According to the magnetic-ion theory,the plasma frequency characteristics have been studied and the radio wave reflection characterisitics of the ionospheres D,E,F1,F2have been explained.in this paper Finally,the propagation time delay in the ionospheres wave guide from Shanxi Observatory to Yunnan Observatroy has been calculated and the significant result is obtained. |
