  earth current
This interval of substorm activity has been interpreted as being in support of a near-Earth current disruption model of substorm onset.
      
These results are interpreted in terms of a synthesis of the very near-Earth current disruption model and the near-Earth neutral line model of substorm onset.
      
Using superposed epoch analysis we compare the air-earth current variations during the 3 h before and after the time of the magnetic X-component minimum with those for corresponding local times on 35 days without substorms.
      
This method was further used to show that the average air-earth current and its fluctuations increase during late expansion and early recovery phases of substorms.

The current and the potential drop under steady state in any branch of a linear, invariable network with any impressed electromotive forces and currents, are usually expressed as the ratio of two determinants. In this paper, short-cut methods for writing down directly the expansion of these determinants in thsir simplest forms are outlined, illustrated and proved. Comparison with similar methods are given. As a check of the result obtained, a method for finding out the total number of terms in the denominator...

在过渡过程时间内,由电源输送到变参数系统中之能量和该系统中之能量损耗,若直接利用过渡过程时之电流和电压来决定,则会遇到求解描述系统中电流变化之变参数微分方程之困难。本文研究如何来避免对变参数微分方程求解之困难,而直接用操作前后系统中之稳态电流和稳态电压来决定上述能量的近似计算法。该法适用于一般的具有稳定性振荡的变参数迴路。
