magnetic equator

comparison of ionosonde and incoherent scatter drift measurements at the magnetic equator

在地磁赤道电离层探测和非相干散射漂移测量的比较

On the magnetic equator the needle would remain horizontal.

在磁赤道上磁针会保持水平。

A reversal could knock out power grids, hurt astronauts and satellites, widen atmospheric ozone holes, send polar auroras flashing to the equator and confuse birds, fish and migratory animals that rely on the steadiness of the magnetic field as a navigation aid.

逆转会破坏能量网格，损害宇航员和卫星，加大臭氧层空洞，发送极光到赤道而搞乱鸟类，鱼和迁徙动物，它们依靠磁场的稳定性作为导航帮助。

The worst condition for seismomagnetic observation appears when the fault is located at the magnetic equator, or orients magnetic E-W, or with a focal depth of 10 km o> r more. Under one of such circumstances the corresponding piezomagnetic anomaly can hardly be detected.

在最差观测条件时压磁异常量几乎无法测出，这时断层位于磁纬0°处，或走向为E-W，或埋深为10公里左右。

The magneto-acoustic-gravity waves propagating downwards along the direction of gravitational field may produce directly the PC 1 magnetic pulsation near the equator.

我们还讨论了磁声重波与地磁微脉动之间的关系，沿着重力场方向向下传播的磁声重波，可能直接引起赤道附近的P c1磁脉动。
