Perpendicular anisotropy(PA) in amorphous GdCo alloy films is thought to be produced by shape anisotropy based on columnar microstructure, The anisotropy constant K_u is approximately given by where K_a, K_b and K_(ab) are the coefficients depending on geometrical factors of the columnar structure. M_a and M_b are average magnetization of inner part and magnetic Gb deficient surface layer of a column, respectively. M_a(T) and M_b(T) were Calculated for two different GdCoMo films, whose M_s(T) and K_u(T)have been known from experiments and the shape of their M_s(T) are quite different. The M_a(T) of both films correspond to the M_s(T) curves of GdCoMo films containing some more Gd contents than that of the specimens. M_b(T) of both films exhibit M_s(T) character of Co rich films. Some dependence of K_u on various deposition conditions are explained. By means of the mean-field analysis it is demonstrated that the calculated spin angular moment of Co S_(co)(O) at O K, exchange interaction energies J_(Co-Co) and J_(Co-Gd) are apparently dependent on the estimated volume fraction V_c of nonmagnetic network. With increasing V_c, S_(co)(O) and J_(Co-Gd)monotonically decrease, while J_(Co-Co) increases. In crystalline FeNi films deposited at normal indidence in the presence of a magnetic field, the constant of the in-plane magnetic uniaxial anisotropy is given by where K_(ap) is the part due to atomic pair ordering, (9λ_tλ_rE)/[4(l+μ)] arises from condition of fixed strain of magnetostriction and (14M_t~2M_T~2b)/γ comes from anisotropy of the distances between neighbouring grains parallel to the film plane, which is the result of shape anisotropy of grains and isotropic distribution of grains in the plane. In the formula, t is the temperature of the substrate during deposition, T is the temperature at the time of measurement of K(?), EisYoug's modulus,μ is Poisson's ratio, b is the distance between neighbouring grains in the plane, γ is surface tensile of the grains, and λ is constant of magnetostriction. M_t~2M_T~2 must be replaced by M_T~4 for small grain films. The calculated dependence of both composition and temperature ise in good agreement with experiments.

本文认为,被网状非磁性介质(包括空隙)包围的磁性柱状组织的形状各向异性是Gd-Co系非晶膜磁各向异性的主要来源,由于Gd的易氧化和择优再溅射,使磁性柱表面层的磁性Gd含量低于柱内部,各向异性常数K_u可近似地表为: K_u=K_aM_a~2+k_bM_b~2+K_(ab)M_aM_b,其中M_a和M_b分别为柱内部和表面层构平均磁化强度,K_a,K_b和K_(ab)是与膜结构的几何尺寸有关的系数。根据两种M_s(T)显著不同的偏压溅射Gd-Co-Mo膜的K_u(T)和M_s(T)的实验资料,用上式分别计算了它们的M_a(T)和M_b(T),结果表明,这两种膜的M_a(T)都呈现Gd含量多于平均成份2—4%的Gd-Co-Mo膜的M_s(T)特性,其中M_s(T)有低抵消点的膜还呈现出磁抵消点的特性,M_b(T)则呈现富Co膜的特性。这表明本文的模型基本正确,计算表明,这些膜的非磁性介质占20%以上,且柱的表面层厚度不很薄,用本文的模型还解释了K_u与膜的氧化程度等工艺因素的关系,另外,本文指出,用平均分子场分析所得的Co-Co和Co-Gd间的交换积分,J_(co-co)和J_(co-Gd)以及0°K下的Co的自...

Aerodynamic design of a transonic axial-flow compressor for research purpose has been completed based on Wu's three-dimensional flow theory in turbomachines. Through 5 cycles of iteration between inverse calculations on a single mean S2 stream surface and direct calculations on a family of S1 surfaces of revolution, final convergent solution of the three-dimensional flow is reached. It implies that the coincidence of corresponding streamlines on the two kinds of stream surfaces and approximate equality of parameters on them, such as Vθγ, △s/R and thickness of the stream surfaces. At the same time, the flow passage and the blade airfoil meeting all design criteria are determined. The flow field analysis of supersonic sections has shown that parameters such as Vor, As/R etc. all undergo a sudden jump through the shock.

A whole-field analysis method of laser speckle interferometry for displacement andstrain analysis is described.Three new methods of laser speckle photography,namely,cross-like slotted aperture,rectangular multi-aperture and rotated or displaced aperturemethods are proposed.Results of the theoretical analysis and experimental demonstrationsof these methods show that the adoption of these methods in laser speckle photographyresults in a wide filtering range and at the same time a very strong viewing intensityduring whole-field analysis,making it possible to obtain a clear and variable sensitivityof displacement field distribution diagram similar to a holographic interferogram.Thiswill certainly pave the way for speckle interferometry application and make whole-fieldanalysis more practical.

本文叙述用于位移、应变分析的激光散斑干涉的全场分析法,提出了三种新的散斑照相法:十字缝光阑法、矩形多孔光阑法、移动或旋转孔光阑法.对这些方法进行了理论分析和实验验证.结果表明;采用这些方法进行散斑照相,在全场分析时可以有很宽的滤波变化范围而同时有较高的观察光强,因而可以获得清晰的、位移灵敏度可变的类似于全息干涉图一样的位移场分布图,这无疑为散斑干涉的应用提供了很大的方便,使全场分析法更具有现实性.
