摘要
磁场极其微弱甚至接近零的特殊环境条件在科学研究和技术研发方面具有独特意义。通过被动屏蔽、主动补偿等手段,可在地磁场和各类干扰磁场的环境下实现这种近零磁场。世界各国已根据不同的应用需求建设了高水平近零磁环境装置,国内相关研究也已初步展开。结合近年来的最新成果,详细阐述了此类装置的建设方案与指标特性的现状。
The special environment in which the magnetic field is very weak and even nearly to zero hasunique and important applications in scientific and technology research. Through passive magnetic shielding, active compensation and other approaches, nearly zero magnetic fields can be realized in the ground condition with geomagnetic field and variable magnetic disturbances. Some high level nearly zero magnetic field environment facilities have been built in the world, and domestic researchers also have achieved some developments. Considering the recent developments in this field, the status reviews of these facilities including the construction design and performances are presented.
