单位词用法探析

以单位词为中心词的名词词组的深层结构决定单位词的语法特征和语义特征。该深层结构多半可以通过单位词的转换功能映现为主动句或被动句的表层结构。在表层结构中,主语名词除去语法形位后的最后一个音节和谓语动词的第一个音段的组合在语音上是可接纳的。     

汉语言的二维指向与中国古代文论的简与繁

汉字的“象”性构造和多样性外衍指向,使古代文论的表达具有简约和繁复两种风格。对于深刻的义理用以少总多或具象隐喻“一语而尽”;对于经验世界的多样性,则上下左右反复详言之,使“情貌无遗”。这两种风格,使文论述说表现出虚实相生、繁简结合的诗性之美。     

基于自由二元判决图转换的可测性优化方法

提出了一种基于自由二元判决图转换的可测性优化方法。该方法首先将电路转化为ＦＢ－ＤＤ表达形式，然后用切换单元来替换ＦＢＤＤ中的节点，以形成易测的多级网络，再通过冗余的认定和消除来达到可测性逻辑优化的目的。与以前的可测性设计方法相比，这种方法适用于任意电路，特别是规模较大、不能用两级逻辑表达的电路     

An Expert Elicitation of the Proliferation Resistance of Using Small Modular Reactors (SMR) for the Expansion of Civilian Nuclear Systems

To facilitate the use of nuclear energy globally, small modular reactors (SMRs) may represent a viable alternative or complement to large reactor designs. One potential benefit is that SMRs could allow for more proliferation resistant designs, manufacturing arrangements, and fuel‐cycle practices at widespread deployment. However, there is limited work evaluating the proliferation resistance of SMRs, and existing proliferation assessment approaches are not well suited for these novel arrangements. Here, we conduct an expert elicitation of the relative proliferation resistance of scenarios for future nuclear energy deployment driven by Generation III+ light‐water reactors, fast reactors, or SMRs. Specifically, we construct the scenarios to investigate relevant technical and institutional features that are postulated to enhance the proliferation resistance of SMRs. The experts do not consistently judge the scenario with SMRs to have greater overall proliferation resistance than scenarios that rely on conventional nuclear energy generation options. Further, the experts disagreed on whether incorporating a long‐lifetime sealed core into an SMR design would strengthen or weaken proliferation resistance. However, regardless of the type of reactor, the experts judged that proliferation resistance would be enhanced by improving international safeguards and operating several multinational fuel‐cycle facilities rather than supporting many more national facilities.     

How a System Backfires: Dynamics of Redundancy Problems in Security

Increasing attention is being paid to reliability, safety, and security issues in social systems. Scott Sagan examined why more security forces (a redundancy solution) may lead to less security.⁽ 1 ⁾ He discussed how such a solution can backfire due to three major issues (i.e., “common‐mode error,”“social shirking,” and “overcompensation”). In this article, using Sagan's hypotheses, we simulate and analyze a simple and generic security system as more guards are added to the system. Simulation results support two of Sagan's hypotheses. More specifically, the results show that “common‐mode error” causes the system to backfire, and “social shirking” leads to an inefficient system while exacerbating the common‐mode error's effect. Simulation results show that “overcompensation” has no effect of backfiring, but it leads the system to a critical state in which it can easily be affected by the common‐mode error. Furthermore, the simulation results make us question the importance of the initial power of adversaries (e.g., terrorists) as the results show that, for any exogenous level of adversary power, the system endogenously overcompensates to a level that makes the system more susceptible to being attacked.

身为言意舞乐合节——少数民族审美视域下舞与乐的三重性

舞蹈与音乐作为两种艺术形态,以不同的介入方式深嵌在人类文化历史进程中,相互关联,交错共生。尽管作为两种不同的言说方式,它们分别占有相应的媒介,但是都共享同一本体——“人”。舞蹈与音乐是“人”这一有机体向外凸显主体性的两种面向。因而,舞蹈是可视化的音乐,而音乐是舞蹈的形体提纯。舞与乐之间的这种关系织体便塑造了其本身的“三重性”,即互文性、纳构性和表征性。民族舞蹈与音乐在艺术史的叙事传统中一直紧密协调,互相成就。民族舞蹈与音乐以各自的特质分别在舞台的话语体系中占有各自的言说方式,并不断夯实自身的审美体验。应该说,两者即可合体。     

冗余现象及其对英语教学的启示

冗余信息是指信息传递过程中比实际需要多的信息,它普遍存在于语言中。在语言交际中保持适度冗余是必要的。冗余主要表现为两种形式:信息复现和信息蕴涵。英语语言符号系统本身及语言符号使用过程中均存在大量冗余,前者主要体现在语音、词汇及语法层次上,后者主要体现为重复、宕词、应酬语、感情词语及违反会话“合作原则”。正确认识、把握冗余现象,可从听、说、读、写及测试等方面促进英语教学。     

大学英语写作教学研究与实践
