second-rank
3.Determination of the Second-rank Polarizabilities Tensor β_(xxx) and Estimation of Second-ordor Polarizabilities Vector β_x of Schiff Base Compounds by Solvatochromic Method
4.The second-rank college has its own unique character in students academic bases, students psychology and students management system.
7.Arming at the feature of texture is focused on middle and high frequency components,the method makes two-dimension wavelet package decomposition towards the image,extracts the middle and high frequency components of the first and second rank as eigenvector and uses Euclidean distance as the way of model identification.
