高空核爆时地磁脉动效应的理论研究

Theoretical investigation on the Effect of Geomagnetic Pulsations Produced by Nuclear Explosions

本文对高空核爆时产生的地面地磁脉动效应进行了理论研究。认为受扰磁力线的ＵＬＦ波共振激发有可能是核爆时观测到的地磁脉动的产生机制，并讨论了沿着平行于和垂直于磁场方向传播的ＵＬＦ波。

In this paper ,the effect of geomagnetic pulsations produced by aerological nuclear explosions is investigated theoreticaly. We consider that the resenant excitation of magnetospheric fieal lines may be the production mechanism of geomagnetic pulsations observed on the ground due to aerological nuclear explosion. The propagation of ULF waves along the lines parallel to and perpendicufar to the magnetic field is also discussed.
