The spacewalkers will also remove an experiment that measured the electrical environment around the outside of the station , as it flies through earth ' s magnetic field 太空漫步者也将升级试验来测量当? (没明白这句话- - ,什么是主语? )穿过地球磁场时,太空站外围的电子环境。
But in the earth ' s case , the lines connecting the north and south poles are skewed at the equator , where they should be parallel , in what ' s termed an inclination anomaly 但相对地球磁场,连接南北极磁线在赤道位置变形了,在本应该是平行的地方,通俗地讲曲率变得不规则了。
Earth ' s magnetic field repels most of this onslaught , but some occasionally leaks through as a result of a sudden , explosive release of these particles from the solar wind 地球磁场排斥了大部分的高速粒子流，但仍然有因为从太阳风辐射出的粒子流的突然释放活动导致的渗透。
Earth ' s magnetic field repels most of this onslaught , but some occasionally leaks through as a result of a sudden , explosive release of these particles from the solar wind 地球磁场排斥了大部分冲击力，但是有时由于太阳风中带电粒子突然爆发性的释放，也会泄漏一部分能量。
Most of the protons and electrons of the wind go round this shock wave , and lots of dangerous radiation from the sun is thus diverted away from the earth 大多数太阳风的质子与电子就会围绕这个冲击波四处移动，并且许多的由太阳散发的危险辐射也就会因遇到地球磁场而被转移到别处。
Reconnection is most efficient when the imf has a component that is directed southward ? that is , opposite to the northward direction of the earth ' s magnetic field at the dayside of the magnetosphere 在磁层昼侧，若imf有南向分量，也就是和北向的地球磁场方向相反，则磁力线重连的效率最高。
Head orientation is determined with a commercially available hybrid tracker that combines gyroscopes and accelerometers with a magnetometer that measures the earth ' s magnetic field 在测定头部方向的技术上，我们用的是一种市面上买得到的混合式追踪器，它是由?转仪、加速表以及一个磁力计（测量地球磁场）结合而成的。
Minerals that record past orientations of the earth ' s magnetic field reveal that it has flipped from north to south and back again hundreds of times during the planet ' s 4 . 5 - billion - year history 有些矿物可以记录地球磁场的方向；根据它们的记录所显示，在地球45亿年的历史中，地磁的方向已经反覆南北倒转了好几百次。
Through paleomagnetism , ( the study of the magnetic properties of rocks ) , scientists now have solid proof that the earth ' s magnetic field , and thus the geomagnetic north and south poles , have reversed itself namy times in the past 通过古磁学（岩石磁特性研究） ，科学家现在拥有地球磁场一致证据，因而地磁北极和南极，在过去已经翻转多次。
The field forms a protective shell called magnetosphere that has a radius around 10 times that of the solid earth . but strong eruptions on the solar surface can seriously distort this shell , creating geomagnetic storms 地球磁场形成一个大小约地球直径十倍称为磁层的保护壳，当太阳表面出现猛烈的爆发，便会严重扭曲这个保护壳，形成磁暴。
