批评隐喻分析(critical metaphor analysis,CMA)作为一种语篇的隐喻分析方法,意在揭示语言使用者的潜在意图,不但可深化我们对语言隐喻的理解,还能揭示隐喻在人类思维和交流中的重要作用。隐喻识别作为CMA分析框架中的一个关键步骤,为隐喻阐释和隐喻说明等后续研究工作提供了坚实基础,是CMA中极其重要且不可或缺的一部分。本研究首先对CMA中隐喻识别的融合性和枢纽性进行深入讨论,探究CMA中隐喻识别的发展特性,熟悉CMA的整个分析框架。同时,针对CMA在隐喻识别中存在的客观性不足问题,提出尝试结合大语言模型(ChatGPT)进行隐喻识别的方法,并基于真实研究案例了解该方法的具体实践操作。通过案例,本研究也对使用大语言模型(ChatGPT)进行隐喻识别过程中遇到的问题进行分析和总结,希望通过合理、恰当地应用技术手段,探索人机协作的最佳方式,以提升隐喻识别的客观性,完善CMA的分析框架,更深入地进行语篇的隐喻研究。

Based on the Canadian Standards Association (CSA) criteria,105 pullout specimens were tested to investigate the effect of different rib geometries on bond strength of glass fiber reinforced polymer (GFRP) rebars embedded in concrete. Two kinds of conventional reinforcing rebars were also studied for comparison. Each rebar was embedded in a 150 mm concrete cube,with the embedded length being four times the rebar diameter. The experimental parameters were the rebar type,rebar component,rebar diameter,rebar surface texture,rib height,rib spacing and rib width. Theoretical analysis was also carried out to explain the experimental phenomena and results. The experimental and theoretical results indicated that the bond strength of GFRP rebars was about 13%～35% lower than that of steel rebars. The bond strength and bond-slip behavior of the specially machined rebars varied with the rebar type,rebar diameter,rebar surface texture,rib height,rib spacing and rib width. Using the results,design recom-mendations were made concerning optimum rib geometries of GFRP ribbed rebars with superior bond-slip characteristics,which concluded that the optimal rib spacing of ribbed rebars is the same as the rebar diameter,and that the optimal rib height is 6% of the rebar diameter.

Using agent development tools to construct an agent-based system is a well applied approach. However, the development tools usually do not have the function to check the feasibility about the workflow of the agent system during it implementation stage. Therefore, to develop an evaluation approach to analyze the feasibility of a developing agent system such that the improper workflow of an agent system can be found in the early design stage is a necessary task to reduce the risk of implementation. In this research, a Petri Net （PN） based three-stage evaluation approach was developed. In the conceptual stage, the pitfall of the current agent system developing process was examined and an improvement analysis process was specified. Then, in the system design stage, an evaluation approach which extracted the process log file from a developing agent system into a PN model in terms of a process mining approach-or algorithm was proposed. This model was simulated in a PN simulation package. The agent system performance was evaluated in terms of analyzing the deadlock phenomena of the PN model. Finally, in the implementation stage, the proposed concept was implemented by using an agent developing tool JADE and a PN simulation tool CPN. An agent-based robotic assembly system was used to examine the possible deadlock of the agent system.
