关于真理本质的追问

对真理的澄清和揭示不是对现成摆明到我面前的存在者之是的实在事件所表象出的"真理是"的翻译,因为,就存在者其历史性地存在而言,对真理及其本质的追问和运思就必然把存在者带到存在者的近旁相互照面。此一照面显明了存在者作为存在者整体(共在)之相关存在者归属于世界一体而来的命运的联结。文本的追问表明,真理既不是从意向活动中抽象出来的意见与实在的符合,也不是商业化、市场化时代前提下对所谓受技术理性支配的合理的可接受性的策划,毋宁说,真理作为一种显露标画的乃是思之所思以及命运的广度。

中国高考从传统走向现代——“标准化考试”改革与发展

我国改革开放后的十五年间,高考借鉴外国经验,结合中国国情进行了一系列理论、技术的研究与实践,相应的改革被称为中国高考的“标准化”改革。实践证明,改革整体上大大提高了我国考试的科学化管理水平,实现了从传统考试向现代考试的转变。本文介绍了高考“标准化”改革的历程,客观分析了高考“标准化”改革的主要成果及不尽如人意之处,并提出有益于高考进一步改革与发展的一些启示。     

High-performance hardware architecture of elliptic curve cryptography processor over GF（2^163）

We propose a novel high-performance hardware architecture of processor for elliptic curve scalar multiplication based on the Lopez-Dahab algorithm over GF（2^163） in polynomial basis representation. The processor can do all the operations using an efficient modular arithmetic logic unit, which includes an addition unit, a square and a carefully designed multiplication unit. In the proposed architecture, multiplication, addition, and square can be performed in parallel by the decomposition of computation. The point addition and point doubling iteration operations can be performed in six multiplications by optimization and solution of data dependency. The implementation results based on Xilinx VirtexⅡ XC2V6000 FPGA show that the proposed design can do random elliptic curve scalar multiplication GF（2^163） in 34.11 μs, occupying 2821 registers and 13 376 LUTs.     

3D wind-induced response analysis of a cable-membrane structure

Wind loading is a dominant factor for design of a cable-membrane structure. Three orthogonal turbulent components, including the longitudinal, lateral and vertical wind velocities, should be taken into account for the wind loads. In this study, a stochastic 3D coupling wind field model is derived by the spectral representation theory. The coherence functions of the three orthogonal turbulent components are considered in this model. Then the model is applied to generate the three correlated wind turbulent components. After that, formulae are proposed to transform the velocities into wind loads, and to introduce the modified wind pressure force. Finally, a wind-induced time-history response analysis is conducted for a 3D cable-membrane structure. Analytical results indicate that responses induced by the proposed wind load model are 10%-25% larger than those by the con- ventional uncorrelated model, and that the responses are not quite influenced by the modified wind pressure force. Therefore, we concluded that, in the time-history response analysis, the coherences of the three orthogonal turbulent components are necessary for a 3D cable-membrane structure, but the modified wind pressure force can be ignored.

关于饭店价值的进一步思考

当今饭店业对于顾客价值的研究层出不穷,而这种主流思想将饭店价值引导到一个相对狭隘的层面,导致饭店经营的可持续发展受到冲击。全面分析了饭店价值的组成,提出饭店价值应该不仅仅是为顾客提供服务产品和为业主带来回报,而应该是扩大到包括员工以及社区经济文化的层面。
