西南地区晚古生代深水生物相初探

西南地区晚古生代时位于华南陆板块的南部被动大陆边缘及陆内。自早泥盆世中晚期开始发生裂陷运动,在滇东、黔南和广西地区发生沿北西向为主,北东向为次的拉张裂陷沉降,最终形成由狭长的台问海槽和弧立碳酸盐台地相间排列的古地貌格局。由于浊流的发育、洋流作用,使深水海槽内海水局部混和充氧,各海槽内海水不完全停滞,不同于黑海式全封闭的阻隔式盆地。不同深度的海槽内具有不同的古生物组合,从浅到深,可归入充氧生物相,充氧-贫氧生物相,贫氧-厌氧生物相及厌氧生物相。     

Fashion Color Forecasting by Applying an Improved Back Propagation Neural Network

Fashion color forecasting is one of the most important factors for fashion marketing and manufacturing. Several models have been applied by previous researchers to conduct fashion color forecasting. However, few convincing forecasting systems have been established. A prediction model for fashion color forecasting was established by applying an improved back propagation neural network (BPNN) model in this paper. Successive six-year fashion color palettes, released by INTERCOLOR, were used as learning information for the neural network to develop a reliable prediction model. Colors in the palettes were quantified by PANTONE color system. Additionally, performance of the established model was compared with other GM(1, 1) models. Results show that the improved BPNN model is suitable to predict future fashion color trend.     

惠安女服饰文化的保护与传承研究

惠安女的服饰具有悠久的历史和文化内涵,是汉族民间服饰中的一朵奇葩。然而近几年,在时代的发展过程中惠安女传统文化从生态环境到传承、使用都出现了严重的危机。在保护的过程中,一方面,要对传统文化进行有效地抢救和保护,坚持整体性、原生性原则;而另一方面,亦不能阻碍其正常发展,要正视传统文化的活态性和现代性,促使其焕发新的活力。     

传统服饰中"鱼"纹样的吉祥内涵

研究我国少数民族民间服饰中以"鱼"纹和"鱼饰"为装饰的服饰文化价值.探讨中国民族服饰中的"鱼"纹样的吉祥寓意以及"鱼"文化在服饰中的象征意义.指出服饰中喜闻乐见的"鱼"所蕴含的生殖崇拜特征,祖灵崇拜"以衣寓裔"、认祖归宗的寻根意识和长辈们望子成龙的祈盼和祝福.是人们对平安康健、丰衣足食、安居乐业的美好生活的心理追求的外在表现.     

哈密市水资源可持续利用初探

哈密市位于封闭的哈密盆地,水资源缺乏,以农业用水为主。本文在分析哈密市水资源开发利用中存在的水资源外延开发、地下水位下降、土壤沙化、水资源管理制度不合理、重经济效益轻生态效益等主要问题的基础上指出要实现哈密市水资源可持续利用必须走以节水为中心的水资源开发利用道路,并提出了几点建议。     

甘肃省天水市雷暴日数时空特征分析

利用1961-2010年天水市7个测站雷暴观测数据,运用线性倾向估计、趋势系数、Mann-Kendall检验等统计方法,对年雷暴日数进行分析.结果表明：天水市近50年年雷暴日数呈下降趋势,每10年总次数减少6.3d,但是武山、甘谷呈上升趋势,其他县区均呈下降趋势,清水县减少趋势最为明显,每10年下降2.4d;地理分布特征是：渭北区高于河谷川区,关山区高于渭北区,呈“U”形分布;利用M-K检验法对全市年总雷暴次数检验发现：雷暴日数在2007年发生突变,通过上述的研究,以期对防雷工作的开展起到了一定的指导作用.     

3D Simulation of Two-bar Warp-knitted Structures

In this study,3D computer modeling of simple warp-knitted structures is achieved based on 3D model of warp-knitted loops.Firstly, according to the studying on the geometric structure of warp-knitted loops, Gktepe's 3D solid yarn model is developed,and the dimensions of the warp-knitted loops are obtained;then 3D models of stitch defined by eleven given points and in-lay defined by five given points are built with the method of Non-Uniform Rational B-Spline (NURBS) curves and surfaces.Secondly, according to...
