介绍了建构和谐环巢湖旅游区背景,分析了建构旅游区过程中的非和谐因素,并提出建构和谐还巢湖的战略原则和举措,以期为旅游区建设提供参考。     

东北民族地区新农村建设的思路

民族地区新农村建设既是一项现实任务,又是一项长期而繁重的历史任务.党中央提出的全面建设小康社会及构建社会主义和谐社会目标的实现,最艰巨繁重的任务在农村,特别是经济欠发达的民族地区的农村和牧区.东北民族地区新农村建设伴随东北老工业基地的振兴将面临新的机遇与挑战,就东北民族地区新农村建设的特点、难点及发展思路加以研究与探讨.     

对东北民族地区干部教育培训工作的思考

落实科学发展观,构建社会主义和谐社会,对负有人才培养和智力支持重任的高校提出了更新、更高的要求.作为东北地区的少数民族院校,如何为少数民族和民族地区服务,如何提高民族地区干部队伍的整体素质,构建适应知识经济发展要求的干部教育培训体系,尤为值得关注.     

重视现代化进程中的东北民族研究

我国东北地区自远古以来,既是多民族生存繁衍的地方,又是多种文化交融发展之通道.东北各民族在历史发展进程中创造了丰富多样的民族文化.如今,东北少数民族在现代化、城市化和一体化过程中走在全国各民族的前列,东北民族的发展历程对其他地区民族现代化的实现有重要借鉴意义. 应当重视现代化进程中的东北民族研究.     

考虑光照影响的静态图像感兴趣区域提取

考虑光照对感兴趣区域提取的影响,提出了一种新的基于边缘的感兴趣区域提取算法.该算法基于二维离散小波变换去除了光照对感兴趣区域的影响;并通过对所采集的边缘像素点评价进一步去除了光照在感兴趣区域产生的阴影边缘.将该算法运用于长途客车过道区域的提取.实验结果表明,提出的算法不仅能实现多种情况下的感兴趣区域的自动准确的提取,还能避免光照的影响     

New taxa of Rhagidiidae (Acari: Prostigmata) from North America. Part V. Genus Robustocheles Zacharda,with a key to world species of the genus

Six new species of rhagidiid mites from the Nearctic region, Robustocheles (R.) pascuaria n.sp., R. (R.) similis n.sp., R. (Mexia) longichelae n.subgen, n.sp., R. (Lewia) lacustris n. sp., R. (L.) obscuritata n. sp. and R. (L.) spinaea n. sp., are described. Additional morphological data are given for R. infernalis Zacharda and Elliott which is placed in the new subgenus Mexia. A key to adults of the known four subgenera and 15 species of the genus Robustocheles Zacharda of the world is presented.     

非光滑优化信赖域算法的改进

给出了无约束非光滑优化问题的一种改进的信赖域算法。改进后的算法不仅满足全局收敛性,而且算法中增加的内循环在有限步内必终止,进一步减少了矩阵的运算量。最后给出一些初步的数值实验。     

New theoretical analysis method for the phase center in the Fresnel region of complex structure antennas

A finite domain time difference （FDTD） and second-derivative combined method is proposed for the evaluation of phase center in the Fresnel region of complex structure millimeter antennas. This method adopts FDTD＇s near to far field transformation to obtain the fields in Fresnel region and then applies the second-derivative method to calculate the phase center. The adoption of FDTD efficiently overcomes the difficulties arising from the existing calculation methods＇ requirements for the radiation analytical formula of some complex antennas, which makes the existing second-derivative method more applicable in engineering. Also, FDTD increases the precision owing to the superposition field calculation from its extrapolation. The correctness of this proposed method is certified with typical examples and the phase center in the Fresnel region of a microwave radiometry calibration corrugate horn antenna is evaluated with the key features.
