摘要: 為了研究鐵磁性材料金屬磁記憶信號與其內部機械應力之間的關系,應用小波分析技術,將金屬磁記憶信號分解為大尺度逼近和細節分量兩個部分,然后計算其細節分量的關聯維數,并考察機械應力與關聯維數變化之間的關系.結果表明,隨著機械應力的增加,磁記憶信號關聯維數降低.

Abstract: In order to study the linking between metal magnetic memory signal of ferromagnetic materials and stress, based on wavelet analysis the metal magnetic memory signal was decomposed into two parties, i.e., the large-scale approach and the detail section. The correlation dimension of the detail section was calculated and the relation of the correlation dimension to stress was investigated. It is shown that with increasing stress the correlation dimension decreases.
