magnetic equator

1. The reason for this is that the magnetic lines near the poles are steeply dipped, while this dip is almost absent near the equator.
   原因在于接近两极的磁力线的倾角急剧增大，而在赤道附近则几乎没有这种倾角存在。
2. On the magnetic equator the needle would remain horizontal.
   在磁赤道上磁针会保持水平。
3. 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Pc1磁脉动。
4. Polynomial Fit of the Magnetic Field in the Near-earth Magnetotail around the Equator Region
   近地磁尾近赤道区域磁场分布的多项式拟合
5. 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。
