学术界对地磁场在应力磁畸变产生过程中的作用存在不同的观点。为了研究地磁场在应力磁畸变产生过程中的作用,以10mm提离值测量了两个过盈装配在一起的圆环和圆销对比试样(对比试样分别在屏蔽地磁场和地磁环境中制成)表面的磁场。实验结果是在地磁环境中制成的试样表面磁场的幅度仅比屏蔽地磁条件下制成的试样表面磁场的幅度大0.85%,这说明在应力磁畸变产生过程中,地磁场几乎不起任何作用。
There are different views on the role of the geomagnetic field in the process of stress-induced magnetic distortion. In order to study the role of the geomagnetic field in the stress-induced magnetic distortion, two diametrically-opposed rings and pins were measured with a 10 mm lift-off value (comparative samples were tested in a shielded geomagnetic field and in a geomagnetic environment Made of) the surface of the magnetic field. The experimental results show that the magnitude of the magnetic field on the specimen surface made in the geomagnetic environment is only 0.85% larger than the magnetic field on the surface of the specimen made under the conditions of shielding geomagnetic conditions, which shows that the geomagnetic field can hardly rise during the stress magnetic distortion Any role
