摘要
文章从理论上阐述了卫星整星充、退磁的机理,对其中地磁场环境中退磁与零磁场环境中退磁的差别,地磁场环境中退磁的时效性,退磁频率、波形、幅值以及周期与退磁效果的关系,磁波形与退磁效果的关系,不同材料、不同尺度的情况下退磁的效果,充磁试验与地磁场环境中材料的充磁的差别以及卫星整星充、退磁试验中退磁场的选取等问题进行了详细的理论分析,对于卫星整星充、退磁试验技术有指导作用。
This paper expounds magnetizing and demagnetizing mechanism of satellites theoretically,including the difference of magnetizing and demagnetizing results between in the geomagnetic field enviroment and in the zero-magnetic field environment,the demagnetizing aging in the geomagnetic field environment,the relationship between demagnetizing frenquency,waveforms,amplitude,period and the demagnetizing effect,the relationship between demagnetizing waveforms and the demagnetizing effect,the demagnetizing effect f...
