摘　　要：用推广了的模型，讨论带状铁磁非晶体金属在弱磁场中的磁化和磁致伸缩特性。导出磁化强度和磁致伸缩作为磁场函数的解析式。磁场小于各向异性场的一半时，得出两个解。把此二解对各向异性轴分布求平均并应用于三个简单模型，得出一些有意义的结果。An extended model describing magnetization and magnetostriction in ferromagneticamorphous metal ribbon is introduced.Analytic expressions for the magnetization and magnetostrictionas a function of applied magnetic field,for arbitrary directions between the anisotropy axis and the ap-plied field direction are presented.The results are expressed as power series expansions of the magneticfield,which are valid for fields that are less than half the anisotropy field. The nonlinear magnetizationand magnetostriction of magnetostrictive ribbon is computed with these expressions for three simplemodels of domain and aulsotropy axis distributions.
