电磁制下常见磁学量的量纲与单位

Dimensions and Units of Common Magnetic Quantities

对常见的磁学量按其在电磁制下的单位名称进行了分类。由它们在国际单位制中的量纲出发,详细推导了它们在电磁制中的量纲,指出了在电磁制下,对单位名称"emu"应视相应的物理量而作不同的理解;对这些量在两种单位制之间的转换关系的共性与个性进行了说明,同时还对电感在电磁制中的量纲与单位进行了推导。

According to the names of units in CGSM,this thesis differentiates the types of common magnetic quantities.From their dimensions in SI,the thesis deducts its dimensions in CGSM,points out the unit ＂emu＂ has different meanings for different physical quantity.The similarities and differences regarding the conversion between SI and CGSM are discussed and the unit and dimension of inductance in CGSM is deducted.
