- Abstract: The transfer of oil and gas resources towards high-risk and high-intensity directions has put forward higher environmental requirements for long-distance oil and gas pipelines, as well as higher demands for operation and maintenance efficiency and safety. Frequent, scattered, bloated and inefficient cleaning and detection operation processes are not conducive to the improvement of intelligent pipeline integrity management systems. This paper studies an intelligent maintenance system integrating cleaning, detection and data. This system is based on a modular concept, adopts multi-modal non-destructive testing technology and a highperformance and efficient edge computing framework, and is an intelligent system integrating structural adaptation, collaboration and data integration. Typical pipeline network field verification. This system has significant advantages in operation efficiency, defect detection accuracy, and data closed-loop management, and has good engineering promotion and application value. It provides a method and technical means for efficient, safe, and intelligent operation and maintenance of long-distance oil and gas pipelines.

The Origin and Grammaticalization of the Frequency Adverb Jin ( 尽) in Chinese Dialects
- Authors:
- Keywords: Chinese Dialects; Frequency Adverb; Jin ( 尽); Etymology; Grammaticalization
- Abstract: The frequency adverb Jin ( 尽) is widely distributed in Mandarin Dialects as well as in Jin, Xiang, Gan, Wu, and Hakka dialects, indicating high-frequency repetition of actions and long-term continuation of states and often carries strong negative evaluative colors. It is derived from the word Jin ( 儘) with the Jingmu ( 精母, voiceless initial consonant) and Shangsheng ( 上声) tone in the Tang Dynasty (7th-10th c.). Its semantic and phonetic evolution led to a new writing form, Jin ( 儘)’s creation on the basis of Jin ( 盡), which was both simplified to the vulgar form Jin ( 尽) in contemporary written language. In the Middle Ancient Chinese (5th-12thc.), the verb Jin ( 尽) developed a causative meaning in the pivotal structure “Jin ( 尽) +N+VP” and gradually evolved along the semantic continuum of “cause > permit > allow > connive”. When the noun (N) in that structure was omitted, the Jin ( 尽) is adjacent to the VP and gradually grammaticalized from a verb into a modal adverb and then frequency adverb. The grammaticalization path of Jin ( 尽) can be summarized as: “verb with the meaning ‘to connive’ > modal adverb > frequency adverb”.

- Keywords: Export-oriented industry; High-quality development; Zhejiang Province; Policy recommendation
- Abstract: Based on Zhejiang Province’s leapfrogging development in foreign trade exports (rising from the 4th to the 2nd nationwide in export volume), this study analyzes the key pathways for its transition from a major foreign trade province to a strong open economy. By stimulating the vitality of the private sector, optimizing trade structures, diversifying market expansion, and strengthening cross-border e-commerce, Zhejiang has achieved resilient growth. The paper systematically examines the current opportunities and challenges facing Zhejiang’s foreign trade sector and proposes four high-quality development strategies: Expanding Infrastructure Investment, Building a Globally Connected Trade Network; Enhancing the Business Environment, Strengthening Policy Support for Enterprise Globalization; Implementing Innovation-Driven Development, Breaking Trade Barriers Through Technological Breakthroughs; Engaging in International Rule-Making, Shifting from “Follower” to “Leader”. The research results provide solutions with both theoretical value and practical significance for the high-quality development of extroverted enterprises in Zhejiang Province.

- Keywords: Psychological capital; Social capital; Innovation potential; Mediating effect; Moderating effect
- Abstract: This study investigated the influence and mechanism of social capital on innovation potential through the 2018 sample data of the China Family Panel Studies (CFPS). 12,318 Chinese people were identified as research subjects, and a model was constructed and validated to explore the relationship between social capital and innovation potential. The results showed that: (1) Both social capital and psychological capital were significantly and positively related to innovation potential; (2) Psychological capital played a partial mediating effect in the relationship between social capital and innovation potential; (3) Psychological capital played a moderating effect in the relationship between social capital and innovation potential — when individuals had a higher level of psychological capital, social capital showed a more substantial facilitation effect on innovation potential. These findings enrich the theory of innovation and provide cross-cultural evidence to better exploit the role of innovation in economic development and social progress.

A Study on Emotional Resonance of the Short Drama Escape from the British Museum Based on Multimodal Analysis
- Authors:
- Keywords: Multimodal Discourse Analysis; Visual Grammar; Online Short Drama; Emotional Resonance; Cultural Communication
- Abstract: Using Zhang Delu’s multimodal discourse analysis framework, this paper investigates the modal synergy and emotional resonance construction mechanism of the online short drama Escape from the British Museum from four levels: culture, context, content and expression. The results show that the cultural layer embeds “cultural relics home” into the collective memory. The context layer makes the narrative everyday through “blood title + civilian scene.” The content layer combines the desire to return home with perceptible audio-visual stimulation. The expression layer anchors the identity with “family.” The resonance between linguistic and non-linguistic modalities drives the audience to shift from cognitive recognition to emotional identification. Multiple modalities interact collaboratively, forming emotional peaks. This interaction connects with the audience’s social practice (likes, retweets, topic participation) to complete the emotion-behavior closed loop. This model reveals the role of multimodal synergy in promoting audience emotional resonance.
