| 摘 要： | 针对实验中磁场对超冷原子团温度和密度的测量的影响,提出了用三组轴向相互垂直的线圈产生的磁场来补偿的理论模型,并根据实验条件对理想模型进行修正.通过这个理论模型,不仅能达到空间某点磁屏蔽的要求,而且可以准确预计有关实验环境的磁感应强度分布.

| Abstract: | It was proposed that a theoretic model of magnetic shield that counteracts earth's magnetic or other disturbing magnetic field by three mutually perpendicular groups of coils.After comparing it with the experimental data,it was known that zero magnetic field could be attained by the device both in theory and in experiment.This model can be easily adjusted to the condition of lab and zero magnetic field can be attained in experiment.It can also be used to anticipate the distribution of magnetic strength in a precision measurement. |
