高师体育教育专业球类课程实施素质教育的理论与实践研究

在素质教育思想指导下，高师体育教育专业球类课程如何面对新形势、新要求、新任务，培养出社会需要的高素质多能型人才，是每一位从事高师体育教育工作者的一项十分重要又亟待解决的问题．本文针对体育教育专业球类课程教学与素质教育不相适应，进行了教学改革，旨在为全面贯彻党的教育方针和深化体育教学改革提供有益的参考．     

生物质谱在生命科学中的应用

生物质谱因其高灵敏度、高准确度、快速、易于自动化等特点，使其在核酸化学、蛋白质组学、糖生物学、细胞信号转导等生命科学领域得到了广泛应用．随着生物质谱在生物研究领域的普及和仪器自动化程度的不断提高，该技术的发展将会更加迅速。     

基于UML的LCA中产品系统的建模研究

从产品系统本身的内在规律和产品全生命周期的观念研究了生命周期评价(LCA)的对象——产品系统及其特性，建立了产品系统概念模型；利用统一建模语言(UML)建立产品系统的结构模型、功能模型和信息模型，并描述产品系统的建模过程。     

美学在今天何以成为可能——兼论吴炫的《否定主义美学》

否定主义美学观认为,美学不仅要研究美的现成形式(符号),更重要的是探求这些形式(符号)为何美之原因,以信它之所以诞生的动力机制等更重要的深层问题.其代言人吴炫主张,美并不存在于任何现成的、既有的主客观状态中;恰恰相反,它指向一种未来的可能性世界--理想化、创造性、生成性的价值世界.人类与美借此创造性过程而实现回顾契合.换言之,它旨在否定美的现成性、既定性价值,肯定美的不断生成性、未来理想性和人的创造性价值.

A TCAM-based Two-dimensional Prefix Packet Classification Algorithm

Packet classification (PC) has become the main method to support the quality of service and security of network application. And two-dimeusioual prefix packet classification (PPC) is the popular one. This paper analyzes the problem of ruler conflict, and then presents a TCAM-based two-dimensional PPC algorithm. This algorithm makes use of the parallelism of TCAM to lookup the longest prefix in one instruction cycle. Then it uses a memory image and associated data structures to eliminate the conflicts between rulers, and performs a fast two-dimeusional PPC. Compared with other algorithms, this algorithm has the least time complexity and less space complexity.     

A Study on the Surface Structures of Viscose-based Activated Carbon Fiber by FT-IR Spectroscopy and XPS

Using viscose fiber (VF) as starting material and common steam as activating agent, formation of oxygen structures in activated carbon fiber is investigated. In the preparation of samples, VF was first heated at temperatures between 450℃ and 900℃ in N_2 artmosphere. Then, in a successive activation stage, the product carbonized at 600℃ was activated in steam at 450-900℃ for 30 min, and at 600℃ for 5-30 min. The other carbonization products were activated at 600 and 900℃ for 30 min respectively. The products activated at 900℃ were then activated at 450℃ for 30 min again. The starting materiah carbonized products and all activation products were examined by FT-IR spectroscopy and some products were examined by X-ray photoelectron spectroscope (XPS). And the yields of the carbonized and activated products were calculated. By analysing these spectra, the amount of oxygen-containing functional groups of the activated products attained under various activation time, various activation temperature and

On the Performance of Punctured Turbo Codes

IntroductionTurbo codes, first introduced by Berrou et al.[1],have attracted the attention of many researchers for theirremarkable coding gains close to theoretical limits, yetadmitting a relatively simple iterative decodingtechnique[2]. Since then, abundant of fruitful results on theperformance of turbo codes have been published, in whicha distance spectrum interpretation was presented by [3]and a super trellis structure of turbo codes was derived by[4]. An analytical…
