The wave propagation and refraction of type "O" irregularities in the counter-electrojet conditions is investigated with a model electrojet in terms of the linear theory of the electrojet instability.

本文分析了反向赤道电射流条件下的不均匀性的对流放大特性。根据电射流不稳定性的线性理论，对一个分层均匀的电射流的模式的数值计算表明：在反向电射流条件下，电射流不均匀性有如下的特性：在波的传播过程中，在上电射流区内，波矢向下旋转，在下电射流区内，波矢向上旋转；在驱动电场E_D数值相同的情况下，反向电射流条件下的射线路径积分增长率r比正常电射流情况的要小得多。

Wormholes are inherently unstable, and will eventually collapse if they are left on their own.
