In the Chinese character intelligent formation system without Chinese character library, it is possible that the same basic element in different Chinese characters is different in position, size and shape. The geometry transformation from basic elements to the components of Chinese characters can be realized by affine transformation, the transformation knowledge acquisition is the premise of Chinese character intelligent formation. A novel algorithm is proposed to ac-quire the affine transformation knowledge of basic elements automatically in this paper. The interested region of Chi-nese character image is determined by the structure of the Chinese character. Scale invariant and location invariant of basic element and Chinese character image are extracted with SIFT features, the matching points of the two images are determined according to the principle of Minimum Euclidean distance of eigenvectors. Using corner points as identifi-cation features, calculating the one-way Hausdorff distance between corner points as the similarity measurement from the affine image to the Chinese character sub-image, affine coefficients are determined by optimal similarity. 70244 Chinese characters in National Standards GB18030-2005 character set are taken as the experimental object, all the characters are performed and the experimental courses and results are presented in this paper.

The pulp and paper industry produces a large amount of colored effluent in the pulping,bleaching,and papermaking *** wastewater from the pulp washing and bleaching stages is also known as mid-stage pulping effluent,which is difficult to treat due to its toxicity and dark *** paper reports a novel Fe/C micro-electrolysis process for the treatment of the mid-stage pulping *** show that this process is effective in removing the color under optimal reaction *** electron microscopy(SEM)and Fourier transform infrared spectroscopy(FTIR)analyses indicate that the colored pollutants were removed from the wastewater in the Fe/C micro-electrolysis by adsorption,collection and filtration *** Fe2+ions produced in the micro-electrolysis process functioned as Fenton’s reagents with H2O2 in the follow-up oxidation stage,which enhanced the removal of chemical oxygen demand(COD)and color.

LiMn2O4 thin films of different thickness were derived from solution deposition and heat treated by rapid thermal annealing. The phase identification and surface morphology were studied by X-ray diffraction and scanning electron microscopy. The electrochemical properties of the films were examined by galvanostatic charge-discharge experiments and electrochemical impedance spectroscopy. LiMn2O4 thin films of different thickness derived from solution deposition and rapid thermal annealing are homogeneous and crack free with the grain size between 20 nm and 50 nm. The specific capacity of these films is between 42 and 47 μAh· cm^2· μm^-1. The capacity decreases with the increase of discharge current density. The capacity loss per cycle increases from 0.012% to 0.16% after being cycled 50 times as the film thickness increases from 0.18 μm to 1.04 μm. The lithium diffusion coefficients of these films are in the same order of 10-11 cm^2· s^-1.

In the Chinese character intelligent formation, the same basic element has different position, size and shape in different Chinese characters. The transformation from the basic element to the Chinese character can be realized by affine transformation, and a novel approach was proposed to acquire the transformation coefficients of basic elements. The interested region was determined based on the structure of Chinese character, scale invariant and location invariant was extracted with SIFT features;meanwhile, rotation invariant was removed. The matched points was determined by Euclidean distance of eigenvectors, the best of three pairs non-collinear points were selected by using particle swarm optimization （PSO） algorithm which take normalized correlation coefficient as fitness function. 27533 Chinese characters in National Standards GB18030-2000 character set were taken as the experimental subject. Finally, the experimental processes and results were given in this paper.
