| 1 | Quantum phase transition and entanglement in Li atom system显示文摘By use of the exact diagonalization method, the quantum phase transition and en- tanglement in a 6-Li atom system are studied. It is found that entanglement appears before the quantum phase transition and disappears after it in this exactly solvable quantum system. The present results show that the von Neumann entropy, as a measure of entanglement, may reveal the quantum phase transition in this model. | SI LiMing1 & HOU JiXuan2 1 Department of Electronic Engineering, School of Information Science and Technology, Beijing Institute of Technology, Beijing 100081, China 2 Laboratoire de Chimie, UMR 5182 CNRS, Ecole Normale Supérieure de Lyon, 46, Allée d’Italie, F-69364 Lyon Cedex 07, France | 2008 | Science China(Physics,Mechanics & Astronomy)2008,51,11: | 6 |
| 2 | Distribution of aluminum species and the characteristics of structure of poly-aluminum-chloride-sulfate(PACS)显示文摘A series of poly\|aluminum\|chloride\|sulfate (PACS), which has different basicities (γ) and Al 3+ /SO 2- 4 molar ratio, has been prepared and dried at 105℃ and 65℃, respectively. The distribution of aluminum species of PACS was examined, and the effect of γ value, Al 3+ /SO 2- 4 molar ratio, dilution on the distribution of aluminum species of PACS was also investigated by using Al\|ferron timed complex colorimetric method. The IR spectroscopy and X \|ray diffraction were used to study the effect of γ value, Al 3+ /SO 2- 4 molar ratio and the drying temperature on the structure of PACS. The experimental results show that Al 3+ /SO 2- 4 molar ratio has a great effect on the distribution of aluminum species, but the dilution has a little effect on the distribution of aluminum species. The lower the Al 3+ /SO 2- 4 molar ratio, the higher the proportions of the polymer and colloidal species in PACS. The polymeric degree of PACS was related to γ value and Al 3+ /SO 2- 4 molar ratio. Drying temperature has an influence on the structure and the solubility of solid PACS products. | GAO Bao\|yu, YUE Qin\|yan, YU Hui, WANG Yan (Department of Environmental Engineering, Shandong University, Jinan\ 250100, China.

| 19 | The Application of the Edge Sharpening Operator to the Breast Near-Infrared Imaging显示文摘The principles of Gradient operator, Laplacian operator, LOG operator and Sobel operator are discussed. Certain features of breast can be extracted in different degrees and aspects from original images by applying four edge sharpening operators to the breast near infrared imaging. A great number of cases prove that compared with the other three operators, the improved Sobel operator can effectively extract the structural features of the breast from an original image. It can be concluded that the improved Sobel operator can assist in diagnosing breast diseases. | Xiang Yan 1 , Li Kai yang 1 , Yang Xuan dong 1 , Wang Xiao fang 2 ,Zhang Xian lin 2 ,Zhu Yi jun 3 1.
