本文以新冠肺炎疫情报道中的多模态隐喻现象为例,从社会认知角度探讨了多模态隐喻所具有的应急语言能力及其体现。本文认为,多模态隐喻通过隐喻加工具有更强的表象力、行事力与建构力,其应急语言能力主要体现在以下几个方面:信息传递、舆情引导、号召动员、语言抚慰、心理援助、鼓舞士气、凝心聚力和人文关怀等。基于此,本文提出了三项应急语言能力规划建议。

本文基于关联理论构建电影中幽默生成机制的三种模式,分析其影响因素,探讨其生成过程,并揭示其认知本质。研究发现:(1)电影中的幽默生成机制本质上是幽默的认知加工机制,幽默的生成过程是一个认知加工过程,该过程能否顺利完成,受语言或非语言输入信息、认知语境、关联性、信息意图、交际意图等因素影响,受认知主体的身体经验、百科知识、逻辑能力等因素制约。(2)电影中的幽默生成机制主要有三种模式:最大关联与最佳关联的冲突模式、信息意图与交际意图的冲突模式、语言或非语言与社交语境的冲突模式。在幽默生成时,这三种模式是一个动态连续统,可以并存。(3)在电影中,生成幽默的范式、路径和模态更加丰富。通过这些范式、路径和模态提供明示信息,强化了语境效果,从而使三种模式的反差更加凸显,这种强烈的反差凸显使电影中的语言元素和非语言元素相对于单纯语言范式和路径更加容易生成幽默。

时空性研究目前主要集中在语言结构和语法形态上,观点有二:1)汉语强空间性与英语强时间性;2)英语或汉语时空同态。但是,到目前为止,从语义角度,还鲜有学者对此方面进行研究。本文从语义角度出发,通过英汉习语语义生成的跨空间映射,包括... 详细信息

时空性研究目前主要集中在语言结构和语法形态上,观点有二:1)汉语强空间性与英语强时间性;2)英语或汉语时空同态。但是,到目前为止,从语义角度,还鲜有学者对此方面进行研究。本文从语义角度出发,通过英汉习语语义生成的跨空间映射,包括单域转喻映射、双域隐喻映射和多域概念整合映射,探究英汉习语时空性思维异同。基于分析与讨论,本文得出如下结论:1)汉语习语语义生成具有强空间性特质;2)英汉习语语义生成具有弱时间性的共同特征。

By using a novel meta-resonator structure, a miniaturized, surface mountable, shared aperture, and hybrid electric/magnetic dipole pattern diversity antenna is proposed for Internet of things（IoT） applications. By exploring the shared electric（E-dipole） and magnetic dipole（M-dipole） structures, a novel T-shaped split-ring resonator（SRR） with even and odd modes is presented and studied by current distributions and equivalent *** and omnidirectional（monopole-like） patterns are achieved by exciting the M-dipole and E-dipole modes of the T-shaped SRR, respectively. To validate the proposed design, this shared aperture metamaterial-inspired pattern diversity antenna with a small size of 0.295λ0× 0.0065λ0× 0.115λ0is fabricated and measured. The measured overlapped-10 dB bandwidth is from 3.40 GHz to 3.63 GHz（7.0%, covering the LTE B42 band） and the port isolation is greater than 23 dB. Both two modes achieve a good radiation efficiency better than-0.79 d B（>83.0%）.

With the development of the transportation industry, the effective guidance of aircraft in an emergency to prevent catastrophic accidents remains one of the top safety concerns. Undoubtedly, operational status data of the aircraft play an important role in the judgment and command of the Operational Control Center(OCC). However, how to transmit various operational status data from abnormal aircraft back to the OCC in an emergency is still an open problem. In this paper, we propose a novel Telemetry, Tracking,and Command(TT&C) architecture named Collaborative TT&C(CoTT&C) based on mega-constellation to solve such a problem. CoTT&C allows each satellite to help the abnormal aircraft by sharing TT&C resources when needed, realizing real-time and reliable aeronautical communication in an emergency. Specifically, we design a dynamic resource sharing mechanism for CoTT&C and model the mechanism as a single-leader-multi-follower Stackelberg game. Further, we give an unique Nash Equilibrium(NE) of the game as a closed form. Simulation results demonstrate that the proposed resource sharing mechanism is effective, incentive compatible, fair, and reciprocal. We hope that our findings can shed some light for future research on aeronautical communications in an emergency.
