文献中常看到矫顽力的几种不同表示方法:Hc、M~(Hc)(或I~(Hc))及B~(Hc),它们之间有什么联系和区别,本文试通过理论分析和数学推导回答这一问题。并愿给读者带来这样一个信息:把一定温度下的矫顽力当作常数看待——这是我们传统的观念——在某些领域将会导致错误。
In the literature often see coercive force of several different ways: Hc, M ~ (Hc) (or I ~ (Hc)) and B ~ (Hc), what is the relationship between them and the difference between this paper through theoretical analysis And mathematical deduction answer this question. And is willing to give the reader the message that treating coercivity at a certain temperature as a constant - that is our traditional notion - will lead to errors in some areas.
