geomagnetic pole

Because climate , material source and sea level change obviously compared with before and after the drift , we speculate that geomagnetic pole drift has significant impact on climate .

漂移发生前后，气候、物质来源与海平面均有较大变化，说明地磁极漂移对气候有着重要影响。

Electronic compass , also known as a digital compass , a modern people use electronic technology to make use of the geomagnetic North Pole set a new device .

电子罗盘，也叫数字指南针，是现代人们用电子技术制作的利用地磁场来定北极的一种新设备。

The velocity changing rate of the position of geomagnetic north pole has not been the same during equal time interval , its changing range is about 10 ° in latitude and 255 ° in longitude .

地磁北极位置的移动并不均匀，在纬度方向的变化范围只有10°左右，经度方向变化有255°。

The analyses show that the actual measure data ( geomagnetic north pole as base ) of directional and horizontal well trajectory and computing data ( Gauss Kriging coordinate north pole as base ) must be corrected to geographical north pole as base .

分析认为，定向井水平井井迹实测数据（以地磁北极为基准）和计算数据（以高斯－克吕格坐标北极为基准）都必须校正到以地理北极为基准上来。

With geomagnetic field model records , several kinds of secular variation of geomagnetic dipole moment and the position of the geomagnetic north pole during the year 0 ~ 2000 A. D are calculated and analyzed .

利用地磁场模型资料，计算和分析了公元0～2000年的地磁场偶极子磁矩和地磁北极位置的长期变化。
