英文摘要：

Through compared the most of military electromagnetic relay＇ s structures, the equivalent magnetic circuits and models of the typical polarized magnetic system and balance force magnetic system were founded. The ultimate differences between magnetic circuits and magnetic models were illuminated based on the polarized magnetic system criterion. The research conclusions can be used to direct the design of military electromagnetic relay.
