太阳活动对VLF传播的一种影响

本文以实验数据为基础,讨论了在太阳耀斑期间产生的相位周期丢失,并用对极传播理论解释了这种相位周期丢失的机理。相位周期丢失是电波传播中的一个重要传播现象,特别是对于低频和甚低频传播。由于太阳耀斑引起的这一传播现象在以往的讨论中比较罕见,因此,对这一问题的讨论具有特殊意义。

THE EFFECTS OF SOLAR FLARES ON VLF RADIOWAVE PROPAGATION

The loss of phase period of VLF radiowaye propagation during solar flares is discussed based on experimental data. Furthermore, the mechanism of loss of phase period is explained utilizing a theory of antipodal propagation. Loss of phase period is an improtant phenomenon of radiowave propagation, especially, the propagation of LF and VLF radiowaves. The phenomenon discussed above is seldomly seen in past references. Therefore, discussion on the problem is of special significant.
