第四篇文章介绍了本文作者使用钴(Co)基非晶态合金完成的一个75×75×75cm~3的小型立方磁屏蔽室,在给定场中测量了屏蔽室内部场强,计算了屏蔽系数。磁屏蔽室是一种提供弱磁环境——零磁空间的有效方法。本文介绍了这个磁屏蔽室的技术性能、材料和装置及测量结果等情况。
The fourth article describes a small cubic magnetically shielded room of 75 × 75 × 75cm ~ 3 made by Co-based amorphous alloy. The field strength in a shielded room was measured in a given field. Shielding factor. Magnetically shielded rooms are an effective way to provide a weak magnetic environment - zero magnetic space. This article describes the technical performance of the magnetic shielded room, materials and devices and measurement results.
