Additional Earth Explorer missions are also being designed to address other aspects of the Earth environment, from the evolution of the magneticfield to the Earth's radiative balance.
更多的地球探测项目正在设计中，涉及从磁场演化到地球辐射平衡等地球环境的其它方面。

To measure the horizontal component of geomagnetism, the "bifilar balance method" is used, together with an additional adjustable magneticfield to compensate the geomagnetic field.
采用“双悬线平衡法”，并利用外加可调磁场与地磁水平分量补偿的方法对地磁水平分量进行了测量。

Energy balance models of the chromosphere-corona transition region are computed for a segment of coronal hole assuming a nonradial magneticfield geometry.
