探悉莲花——宝相花纹样流变分析

主要从莲花纹样源流、佛教艺术和文化渗透性上分析佛教文化在莲花到宝相花的演变中所起的重要作用。这种转变也反映出中华文化的开放性和吸收性,同时对这种纹样流变历程的深入了解,也可以给现代的设计观念继承性创新以启迪。

Virtual Environments and the Acceleration of Experiential Learning

Darius et al. (2007) and Nolan & Temple Lang (2007) give examples of virtual environments that can, for specific purposes, substitute for the real world. We are in the early stages of developments that could revolutionize statistics education by making it possible to capture efficiently important aspects of the thinking and practice of professional statisticians previously learned only from long years of experience. The ability of virtual environments to automate processes provides a potent weapon for tackling the tyranny that Time exercises over such modes of learning. We discuss the many new possibilities that are opened up by virtual environments together with cognitive and pedagogical imperatives to be addressed to ensure that environments actually do teach the lessons they were designed to teach. We echo Nolan and Temple Lang's call for the development of environments to be modular and open source. Taking the R‐project as a model, this can lead to a growing repository of building blocks that make the construction of future environments less costly, thus facilitating the realization of more and more ambitious conceptions.

IEEE802.16a单载波频域均衡方案的仿真

研究了IEEE802.16a宽带无线接入系统的单载波频域均衡(SC-FDE)方案,建立了完整的802.16a单载波频域均衡系统仿真平台,研究了SC-FDE系统的频域均衡、编码和分集增益.仿真结果表明,将SC-FDE系统与判决反馈均衡、信道编码或发送分集结合都能提高SC-FDE系统抗多径干扰的能力.     

构建应对疫情的跨境河流水源保护新机制

跨境河流水源保护对保障跨境水资源安全、促进跨境水资源可持续发展至关重要。结合我国跨界河流水源保护实现联防联控的相关经验,梳理跨境河流水源保护现有机制,并分析疫情发生对跨境河流水源保护的影响,依此提出我国跨境河流水源保护应急管理新机制和长效管理新机制。其中应急管理新机制主要包括:加强联防联控,构建跨境河流疫情防控"水命运共同体";注重信息交流,建立跨境流域突发事件信息共享机制;规范废水处理,建立跨境河流水环境协调保障机制;强化水体监测,建立跨境河流水环境监控预警机制。长效管理新机制主要包括:推动国际合作,建立跨境流域突发事件协同联动机制;加强协同保护,建立跨境河流水源保护的争端解决机制;促进流域公平,建立跨境河流水源保护的利益补偿机制;排除外在干扰,建立健全跨境流域协调机构和评估机制。     

湖南方言新词语探微

湖南方言新词语指的是以湖南省省会长沙为中心，包括全省各地出现的反映社会特有事物或现象的时尚词语。这些新词语常运用比喻、借代、词义的转移、扩大等方式构成，在使用上具有流传性、阶层性、时间性的特点。经济的发展、社会心态的多元化以及湖南传统性格的影响是湖南方言新词语产生的主要原因。     

Intellectual property: the assessment

In recent years, there has been an increase in the commercializationof intellectual property (IP), via such mechanisms as patents,licences, copyrights, and trade marks. New institutions (e.g.science parks), as well as new organizational forms (e.g. researchjoint ventures), have emerged to facilitate the creation andcommercialization of IP. Existing institutions, most notablyuniversities, have become much more aggressive in protectingtheir IP and devising ways to generate additional revenue fromtheir IP portfolios. These trends have important policy implications,which are addressed by the authors in this issue. We summarizetheir contributions and provide some context for assessing thesesalient matters.     

严复宪政思想探析

严复园其特殊的个人经历及知识结构。提出较为系统的宪政思想。同时。严复又认为中国国民素质尚未达到实行宪政的要求，主张缓行宪政，并将实现宪政之希望寄托于“权威”政治，其宪政理想最终在现实面前破灭。     

采用预测算法的卫星CFDAMA MAC协议时延性能分析

提出了地面站采用预测预约算法的混合式按需／自由分配-预测预约（CFDAMA-PR）卫星媒体接入控制协议。CFDAMA-PR协议可采用预定预约时隙或轮询预约时隙发送预约请求。在文中，通过计算机仿真对预定时隙预约CFDAMA-PR、CFDAMA-PA与基本DAMA协议进行性能比较，同时还对轮询预约CFDAMA-PR和CFDAMA-RR协议进行了仿真性能比较，仿真中采用IFP突发信源，仿真结果说明CFDAMA-PR协议采用预测预约算法，实现了更好的时延／吞吐量性能。
