The first is the creation of new magnetic fields from the ambient geomagnetic field.(第一個過程是在周圍地磁場的基礎上產生新磁場。)

The geomagnetic field varies continuously.(地磁場不斷地發生變化。)

The method of regional geomagnetic field modeling is adopted in order to prepare for the reference map of geomagnetism-aided navigation and positioning.(針對性對地磁輔助導航定位中基準圖制備的需要，采用了建立區域地磁場模型的方法。)

There are many methods to measurement the flying attitude, such as solar attitude angle sensor, high-speed photography and geomagnetic field sensor.(飛行體的姿態測試方法有許多種，如太陽方位角傳感器遙測、高速攝影法、地磁傳感器等。)

The daily variation in properties of the Earth, such as the temperature or the local geomagnetic field, or the daily change in sunlight.(地球各種特征每天的變化，如溫度、局部地磁場每天的變化、以及陽光每天的變化。)

Low carbon steel samples were tested under static tension conditions in quest of physical mechanism in geomagnetic field.(為探索磁記憶現象的物理機制，在地磁場環境中，靜載拉伸低碳鋼板狀試件。)

In a infinite and empty space the geomagnetic field falls off in strength with the third power of distance.(在無限和真空的空間中，地磁場在強度上隨距離3次方而衰減。)

Formation cause of geomagnetic field is one of the important difficult problems of geophysics.(地磁埸的成因是地球物理學的重大理論難題之一。)

For instance the geomagnetic Field, the heat flow, the propagation of seismic waves, the force of gravity, etc.(例如，應用地球物理勘探，可以了解諸如地磁場、熱流、地震波的傳播和重力等地球物理性質。)

Weak magnetic signal changes and metal magnetic memory effects of steel tensile samples under the excitation of geomagnetic field were studied.(研究地磁場環境中鋼試件在動拉伸載荷作用下表面弱磁信號的變化以及磁記憶效應。)
