TEMPERATURE DEPENDENCE OF EFFECTIVE MAGNETIC ANISOTROPY OF Fe-Nb-B ALLOY H.H.Zhao1,K.Y.He1,H.C.Yang1,Z.Wang1,L.Z.Cheng1,Y.J.Zhang1 (1.Department of Materials Science and Engineering,Northeastern University,Shenyang 110004,China;2.Tianjin Institute of Technology,Tianjin 300191,China) Abstract:The correlation between the effective magnetic anisotropy ＜k＞ and the temperature T,＜k＞-T curve......
/layered silicate nanocomposite, which possesses excellent properties. The asymptotic homogenization method (AHM) was applied to determine numerically the effective elastic modulus of a two-phase nanoplastic with different particle aspect ratios, different ratios of elastic modulus of the effective particle to that of the matrix and different volume fractions. A simple representative volume element......

and the effective diffusivity of water vapor in frost was deduced. In this model, many parameters were used to describe frost structure, such as pore fractal dimension, channel axes fractal dimension, porosity, maximum and minimum pore dimension, and minimum distance of channel. The results show that this model embodies properly channel curve’s change and its effects on water vapor diffusion. Effective......
