Magnetic heading system ( mhs ) is an essential device used to measure the heading of ships , aircraft and land vehicles 磁航向系统是一种利用地球磁场测量方向的系统。
When describing the magnetic field of the earth we must specify both the direction and the intensity of the field 当描述地球磁场的时候，我们必须强调磁场的方向和强度。
Geophysicists have long known that the source of the fluctuating magnetic field lies deep in the center of the earth 地球物理学家很早就知道，地球磁场变化的原因深藏于地球中心。
We know from magnetic records locked in rocks that the earth ' s magnetic field has reversed many times in the past 我们从锁定在岩石中的磁记录中知道，地球磁场在过去倒转了很多次。
But in the magnetosphere , weather results from the interaction between the earth ' s magnetic field and the solar wind 但在磁层里，太空天气却是由地球磁场和太阳风的交互作用所造成。
In principle , therefore , this rate of recovery could reveal information about the alignment of the earth ' s magnetic field 因此，这种稳定性恢复的快慢实际上反映的是地球磁场的方向。
When they reach the earth ' s magnetic field the energy is tra ferred into visual light around the earth ' s polar regio 当它们到达地球磁场之后，能量便在地球极圈地带转化成可视的光线。
A geomagnetic storm occurs when a violent solar wind hits the earth and severely distorts the earth s magnetic field 地磁暴起因是由于猛烈太阳风冲击地球，使地球磁场急速变形而造成的。
This causes chaos because the human being needs the magnetic field of the earth to maintain it ' s emotional balance and memory 这个引起混乱因为人类需要地球磁场维持它的情感平衡和记忆。
When they reach the earth ' s magnetic field the energy is transferred into visual light around the earth ' s polar regions 当它们到达地球磁场之后，能量便在地球极圈地带转化成可视的光线。
