查询词典 inverses

The calculation results show that the normal component of magnetic intensity is symmetrically distributed around the point of the acting force, where the normal component reach the maximum value; while the tangential component is antisymmetrically distributed around the point of the acting force, where the tangential component inverses its direction sharply.

结果表明，空气中扰动磁场的法向强度和切向强度分布特征明显不同，法向强度关于力作用点对称分布，并且在力作用点处达到最大，而切向强度关于力作用点反对称分布，并且在力作用点处有突变；地磁环境下，磁场对位移的影响可以忽略不计；扰动场强与外力成正比。
