Shape-control of nano-ZnO by changing the solvent

ZnO sub-micrometer sized disk using ethanol/water mixed solution as solvent is synthesized by solvent-thermal process without any additive, while ZnO nanorods are obtained when water is used as solvent. This formation of disk is discussed based on the reaction of Zn-terminated ZnO (0001) plane with ethanol molecule, which results in the passivation of ZnO (0001) planes and lowering the free surface energy of ZnO (0001).     

基于分形特征的目标检测算法概述及仿真

对目前比较常用的基于分形特征的目标检测算法进行了概述，并给出了相应的仿真结果。从仿真结果我们看出基于多尺度分形参数的目标检测算法是一种比较精确的算法，但是计算量太大。从计算量和精确度双方面考虑快速的基于分维数和分形拟合误差的目标检测算法是一种不错的算法。     

Review of Daqing＇s Technologies in 10th Five-Year Plan Period

During the 10^th Five-Year Plan Period, Daqing Oil Field entered the late high water-cut period with the reserve production ratio in imbalance. The oil field development became more and more difficult owing to the inadequate substitute resources. Daqing Oil Field Company has made a series of important and new technological achievements to solve those bottlenecks. The oil field has cumulatively achieved a total of technological results, of which eight items are at the State level, 96 items at the provincial and ministerial level, and 1009 items granted with the patent rights. The oil field has developed a family of exploration and development technologies which are world-leading and self-developed with an independent IPR.
