Analysis is reported on the effect of demagnetizing field upon the feebly magnetic measurement, and calculation is presented to two kinds of ballistic demagnetizing factors which are about non-magnetic cylindrical specimen itself and about its measuring coil. Thus, the errors of H and M measurements in regard tO the demagnetizing field and their correct method as well are given. It may be suggested that a set of standard dimensions for the feebly magnetic measurement is available. 收稿日期: 1983-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 陈笃行 李伯臧 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I5/141 1 ASTM A342-64 (1970) , 1971 Annual Book of ASTM Standards, Part 8, ASTM, 1971, p. 38． 2 直流与交流磁测量,刘湘元等译,上海科学技术出版社,1964,p.100． 3 Bozorth, R.
