地磁场

The oceanic crust thus serves as a magnetic tape recording of the history of the geomagnetic field that can be dated independently

这样海洋壳就扮演了磁带的角色，记录下可以鉴定时间的地磁场的历史。

In fact, the magnetic field changes the ground to calm than its value is very small.

其实地面地磁场变化量较其平静值是很微小的。

The Earth's magnetic axis is inclined at about 12 degree to its spin axis, but 'wobbles' slightly.

地磁场的轴向地球自转轴偏转了约12度，但它存在轻微的"摇晃"。

It is the INTERNAL pressures building up that actually damage the Magnetic Field, so to speak.

如果要说的话，那是一种内在形成的压力来毁坏地磁场。

When a wire loop incises the magnetic force line of the earth magnetic field it will bring about the induction electromotive force an attitude measurement system was designed based on the earth magnetic field orientation sensor .

根据法拉第电磁感应定律，即线圈切割地磁场磁力线产生感应电动势的原理，设计一种基于地磁方位传感器的姿态测量系统。

Magnetic shield, there would be more dangerous radiation reaching the

如果我们没有地磁场的防护，就会有更多的有害射

The South Magnetic Pole is where geomagnetic field lines follow an upward direction.

南磁点是指地磁场线向上延伸的交会点。

As magma rises under the mid-ocean ridge, ferromagnetic minerals in the magma become magnetized in the direction of the geomagnetic field.

当岩浆 从中海脊下涌起的时候，岩浆中的磁铁矿物质按地磁场的方向被磁化。

As magma rises under the mid-ocean ridge , ferromagnetic minerals in the magma become magnetized in

当岩浆从中海脊下涌起的时候，岩浆中的磁铁矿物质按地磁场的方向被磁化。

Considering the ionospheric refractive index in geomagnetic field, the radiowave polarization plane rotation has been calculated. For linear frequency modulation pulse signal, the expression of Doppler shift error due to ionospheric dispersion characteristics is derived.

本文还计算了考虑地磁场时电离层双折射指数特性引起的电波极化面旋转角，推导出对于线性调频脉冲信号电离层介质色散特性引起的合成孔径时间内多普勒频移误差的表达式。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
