This paper focuses on non-destructive testing (NDT) technology for bridges, comprehensively examining its current status and future development trends. It elaborates on the critical role of NDT techniques in ensuring bridge operational safety and evaluating structural performance, while summarizing commonly employed testing methods. The study provides detailed analyses of practical applications for various detection technologies—including ultrasonic imaging, radar, and infrared thermal imaging—and outlines the fundamental components and standard operating procedures of integrated inspection systems. Key challenges in current NDT implementation are identified, such as technical limitations, complexity in data interpretation, and difficulties in establishing and maintaining monitoring systems—major obstacles to technological advancement. The paper identifies three primary future directions: toward intelligent and automated systems, more precise evaluation methodologies integrating multiple data sources, and transition to continuous monitoring with network-based data sharing. Specific recommendations include enhancing R&D and integration of core technologies, improving professional skills among inspectors, and optimizing management protocols and workflows. These measures aim to provide robust theoretical support and practical guidance for bridge engineering safety management, ensuring structural stability, reducing accident risks, and safeguarding public life and property. 展开更多

Based on 2014-2024 data from China’s Ministry of Education National Education Development Statistical Bulletin,this study explores the ten-year development trends and quality improvement paths of China’s higher education.It finds that the gross higher education enrollment rate rose from 37.5%to 60.8%over the decade,achieving a leap from popularization to accessibility,with significant growth in enrollment scale,institutional count,and resource investment.However,scale expansion has triggered quality challenges:fluctuating student-faculty ratios,imbalanced type structure,and lagging per capita resource growth.Enrollment growth has no significant linear correlation with full-time faculty growth,but a highly significant positive correlation with student-faculty ratio growth.The study proposes optimizing quality paths via a scale-quality linkage mechanism,faculty structure optimization,increased resource investment,and improved type structure,to provide empirical support and policy reference for China’s higher education transformation from scale-driven to connotation-based high-quality development. 展开更多

Shape is an important quality index of cold rolling strip. Up to now, many problems in the shape control domain have not been solved satisfactorily, and a review on the research progress in the shape control domain can help to seek new breakthrough directions. In the past 10 years, researches and applications of shape control models, shape control means, shape detection technology, and shape con- trol system have achieved significant progress. In the aspect of shape control models, the researches in the past improve the accuracy, speed and robustness of the models. The intelligentization of shape control models should be strengthened in the future. In the aspect of the shape control means, the researches in the past focus on the roll opti- mization, mill type selection, process optimization, local strip shape control, edge drop control, and so on. In the future, more attention should be paid to the coordination control of both strip shape and other quality indexes, and the refinement of control objective should be strengthened. In the aspects of shape detection technology and shape control system, some new types of shape detection meters and shape control systems are developed and have successfully indus- trial applications. In the future, the standardization of shape detection technology and shape control system should be promoted to solve the problem of compatibility. In general,the four expected development trends of shape control for cold roiling strip in the future are intelligentization, coordi- nation, refinement, and standardization. The proposed research provides new breakthrough directions for improv- ing shape quality. 展开更多

We aim to present an overview of the status of adhesives in the wood industry, especially in the area of wood-based panels. The review summarizes the current state of research of two kinds of adhesives, i.e., synthetic adhesives and natural adhesives. Synthetic adhesives, consisting of urea-formaldehyde resins （UF）, phenol-formaldehyde resins （PF）, polyvinyl acetate emulsion （PVAc） and isocyanates, are widely used. For UF, most investigations are concerned with the reduction of free formaldehyde; for PF, most studies focus on finding new chemicals to replace phenol. PVAc has poor properties, but these can be improved by a blending reactions and copolymerization with other chemicals. Isocyanate is an environmentally friendly synthetic adhesive, but also suffers from inadequate properties. Natural adhesives, such as protein/starch, lignin and tannins, have poor bonding effect that limits their level of use, but their main advantages are that they are environmentally friendly and a renewable resource. Studies of modification can improve the bonding performances and gradually cause natural adhesives to become applied in industrial production. Some proposals for future development and the importance of environmentally friendly adhesives are provided, which will be helpful in future theoretical and experimental research. 展开更多
