The Hot Dry Rock(HDR)is considered as a clean and renewable energy,poised to significantly contribute to the global energy decarbonization agenda.Many HDR projects worldwide have accumulated valuable experience in efficient drilling and completion,reservoir construction,and fracture simulation.In 2019,China Geological Survey(CGS)initiated a demonstration project of HDR exploration and production in the Gonghe Basin,aiming to overcome the setbacks faced by HDR projects.Over the ensuing four years,the Gonghe HDR project achieved the first power generation in 2021,followed by the second power generation test in 2022.After establishing the primary well group in the initial phase,two directional wells and one branch well were drilled.Noteworthy progress was made in successfully constructing the targeted reservoir,realizing inter-well connectivity,power generation and grid connection,implementing of the real-time micro-seismic monitoring.A closed-loop technical validation of the HDR exploration and production was completed.However,many technical challenges remain in the process of HDR industrialization,such as reservoir fracture network characterization,efficient drilling and completion,multiple fracturing treatment,continuous injection and production,as well as mitigation of induced seismicity and numerical simulation technology. 展开更多

Internet buzzwords,as distinct forms of language,consist of short sentences yet carry rich meanings and spread rapidly.To better study this intriguing and unique linguistic phenomenon,this paper employed conceptual integration theory for its powerful explanatory capabilities to analyze the origins,composition,and emergence of meanings of internet buzzwords over the past four years.These 40 internet buzzwords can be categorized into five types:semantic derivation,generalization,abbreviation,metonymy,and compounding.Furthermore,this paper conducted cognitive analysis from different conceptual integration network perspectives,elucidating specific cognitive operations involved in the construction of meanings and revealing the emergence process of layered meanings in recent internet buzzwords over the past four years. 展开更多

This paper studies and construes the meaning construction of idiom based on blending model,intending to use the blending model to reveal the meaning construction mechanism of idiom so as to make people understand that the meaning of idiom is constructed through the non-compositional integrated approach.The study shows that the conceptual blending is a primary means of encoding the metaphorical meaning of idiom.It blends the concepts of different cognitive frames,through the cross-space mapping and projection,to form a new concept,which is the metaphorical meaning of idiom.The process of idiom’s meaning construction is essentially a semantic leap,thus,a process of frame-shifting.Moreover,the national cognitive and cultural models play a very important role in the process of meaning construction of idiom.The cognitive model provides a guiding for the meaning construction of idiom,and this guiding become a kind of reality induced by the cultural model eventually. 展开更多

The multimodal discourse has been playing a significant role in modern society since its springing-up from the 1990s.Based on the theoretical framework of Visual Grammar(VG)put forward by Kress&van Leeuwen(1996),this study,from the per⁃spective of multimodal discourse analysis,aims at exploring the meaning construction in the emblem of 2019 Beijing International Horticultural Exposition.It is found that an emblem can be interpreted with other modes such as visual image,color and pattern de⁃sign apart from verbal language,which will not only work to participate in the overall meaning construction with mutual interaction,but also analyze how sociocultural background,local customs and humanity spirit are reflected through these forms. 展开更多

Media discourse in the context of intercultural communications is an important channel that countries and cultures use to communicate. It is also a process of meaning interpretation and knowledge production, which exerts a great impact on the establishment of the world's cultural order. This paper discusses media discourse in intercultural communications theoretically from the perspective of knowledge production, media dialogue and meaning construction. It is suggested that an effective ideographic mechanism be developed and improved, and the essential meaning of Chinese culture be initiatively exported and integrated into a knowledge system of cognition and understanding about the world to promote the understanding and exchange between China and other countries and to help create an equal and reasonable world cultural order. 展开更多

This study proposes a teaching system environment for the training of English guides of stone inscription relics based on analysis and describes the roles played by each element in this system environment. The elements listed in the system environment can contribute themselves only under the support of the whole system environment. Therefore, the effect of the meaning construction is really the coordination result between the elements of the system environment. It can effectively improve the training efficiency of the training of English guides of stone inscription relics. 展开更多

This paper presents a Method for the squaring of a circle (i.e., constructing a square having an area equal to that of a given circle). The construction, when applied to a given circle having an area of 12.7 cm<sup>2</sup>, it produced a square having an area of 12.7 cm<sup>2</sup>, using only an unmarked ruler and a compass. This result was a clear demonstration that not only is the construction valid for the squaring of a circle but also for achieving absolute results (independent of the number pi (π) and in a finite number of steps) when carried out with precision. 展开更多

The wide acceptability of Nigerian hip hop music,home and abroad,indicates increasing value of the inclusion of local popular languages in the composition and performance of the music.In the text of many of the award winning singles and albums are mixtures of different languages ranging from English,Pidgin English,Yoruba,Igbo and other local dialects.Drawing on Ferdinand de Saussure’s theory of structuralism,this study examines meaning construction in hip hop music in Nigeria.By focusing on the Nigerian hip hop artists,who adopt different slangs embedded with codes considered absurd within the mainstream cultural milieu,the study closely investigates constructed meanings in the lyrics of four Nigerian award winning hip hop artists.All the artists adopted multilingual codes-switching from one language to another in presentation of their messages.The codes in the songs generally symbolise and present messages or meaning that appears out of the mainstream cultural meanings.Listeners and artistes meet at the level of interpretations.The article argues that Nigerian artists creatively present a sub-culture where they and their fans can relate through codes and words embedded with symbolic meanings shared by both artists and fans. 展开更多

In the context of "two-wheel drive" development mode, China's construction land shows significant expansion characteristics. The carbon emission effect of construction land changes is an important factor for the increase of carbon emissions in the atmosphere. In this study, the drivers of carbon emissions in Anhui Province from 1997 to 2011 were quantitatively measured using the improved Kaya identity and Logarithmic Mean Divisia Index. The results show that: economic growth, expansion of construction land and changes in population density have incremental effects on carbon emissions. The average contribution rate of economic growth as the first driver is 266.32 percent. The construction land expansion is an important driving factor with annual mean carbon effect of 6.4057 million tons and annual mean contribution rate of 187.30 percent. But the change in population density has little impact on carbon emission driving. Energy structure changes and energy intensity reduction have inhibitory effects on carbon emissions, of which the annual mean contribution rate is -212.06 percent and -158.115 percent respectively. The targeted policy approaches of carbon emission reduction were put forward based on the decomposition of carbon emission factors, laying a scientific basis to rationally use the land for the Government, which is conducive to build an ecological province for Anhui and achieve the purpose of emission reduction, providing a reference for the research on carbon emission effect of changes in provincial-scale construction land. 展开更多
