With modern multiple stratigraphic classification as the theoretical basis, the density, susceptibility and residual magnetization of regional lithostratigraphic formations as the research objects , and the Fisher grouping for maximum homogeneity as the mathematical means, the authors defined and determined physical stratigraphic boundaries of the stratigraphic column in Hebei Province.
以现代地层学多重划分为理论依据,以岩石地层单元组的密度、磁化率、剩余磁化强度及厚度加权算术平均值等物性参数为研究对象,以有序地质量最优分割方法为数学手段,进行河北省全区综合地层柱物理地层界线的厘定,并对其地质意义进行了初步讨论。
Based on the former work,the influences of the film thickness, the working pressure, the external stress and theremanent magnetization on the domain structures of the Co_(60)Fe_(20)B_(20), Co_(9.
应用磁力显微镜研究薄膜磁畴结构的变化部分主要研究了工艺、外加应力与剩余磁化强度对软磁薄膜磁畴结构的影响。
