Abstract.National economics has different disciplinary origins both domestically and internationally, and this discipline has strong complexity and comprehensiveness. There are four problems in the teaching mode of national economics in China, including a one-way indoctrination teaching mode, unclear curriculum levels, closed curriculum organization form, and outdated teaching methods. In this regard, the following paths should be taken to promote the reform of the teaching mode of national economics, namely establishing a people-oriented teaching concept, strengthening the setting of courses at … Read more →

Abstract.With the deepening and development of research in the field of concrete both domestically and internationally, the performance of concrete in high temperature environments in China plays a leading role. In the past, people's understanding of the performance of concrete in high-temperature environments mostly focused on static mechanics, as static mechanics is the foundation of the entire concrete industry. In the current literature, there is a lot of important knowledge and information on how to improve the performance of concrete. This article reviews the relevant knowledge on improving … Read more →

Abstract.In the context of the new era, the complexity and comprehensiveness of ideological and political education have become more and more obvious, due to the rapidly changing external environment, there is its own fracture and fragmentation phenomenon, accelerating innovation is important. In order to satisfy the new requirements of ideological and political education in the new circumstances, colleges and universities can take traditional teaching concepts and methods as the basis for the implementation of ideological and political education, associated with the actual requirements of the students … Read more →

Abstract.Based on coupling coordination degree model, this paper calculates the coupling coordination between basic old-age insurance and Economic development in 30 provinces (municipalities and districts) in China from 1997 to 2017 (excluding Xizang, Hong Kong, Macao and Taiwan), and analyzes its influencing factors using the spatial Durbin model. Firstly, the coupling coordination between basic old-age insurance and Economic development is on the rise from the stage of reluctant coordination to the stage of primary coordination. However, the regional differences continue to expand, and the spatial … Read more →

Abstract.As integrated circuit technology continuously evolves towards nanometre scales, the susceptibility of chips to Electrostatic Discharge (ESD) under low voltage conditions has significantly increased, posing greater challenges for ESD protection design. Traditionally, ESD protection strategies have centred on high-voltage applications, employing complex and cumbersome circuits and components to enhance tolerance. However, these methods often underperform in low-voltage CMOS processes due to excessive leakage currents, increased chip area, and an inability to meet the requirements of low power … Read more →

Abstract.Currently, there is no universally recognized valve disc slight opening identification technology for online verification in safety valves. For spring-loaded safety valves, there is no online verification method available when the mid-range value is unknown. Particularly in the online verification of spring-loaded safety valves, the existing methods generally suffer from the drawback of poor verification accuracy. This paper proposes a novel approach, centered around a computer system, comprising an acoustic emission sensor, a signal amplifier, a valve stem lifting device, and an additional … Read more →

Abstract.With the in-depth application of artificial intelligence, AR/VR, big data, 5G and other emerging technologies in the field of education and teaching, human education is transforming and evolving to the stage of smart education. The connotation and characteristics of "smart education" require teachers to improve their professional ability under the premise of mastering the theoretical concepts such as constructivism and connectionism, and finally realize the transformation of their roles in the teaching of "wisdom education". On the basis of combing the relevant education and teaching theories … Read more →

Abstract.The fluorescent characteristics of arsenic and mercury determine that the atomic fluorescence method can be used to determine its content in the natural environment of the atmosphere, soil, and water body to effectively understand the arsenic and mercury pollution in the natural environment. Essence According to this experimental analysis, it can be seen that the application of the atomic fluorescence method is better, which can meet the needs of arsenic and mercury analysis in different situations in different situations. Compared with previous measurement methods, the atomic fluorescence … Read more →

Abstract.Sichuan-Tibet Railway Changdu-Linzhi section construction power supply project (Phase II) by Tibet Power Grid Co. 4900m), the mountain is treacherous, the foundation excavation is difficult (mostly rock foundation). Among them, 3 times across 35kV lines, 1 time across 220kV lines, 1 time across the Nujiang River, across the construction is more difficult. At present, China often use galvanized steel, galvanized copper and other traditional grounding materials, due to corrosion phenomenon caused by the increase in grounding resistance, affecting the frequency current, lightning current … Read more →

Abstract.In response to the ethical issues arising from the development of intelligent robot technology, this paper first analyzes the ethical issues that have arisen in the development of intelligent robot technology from three aspects: the impact on the definition of human subjectivity, the impact on human creativity, and the impact on human privacy. Then, from the technical, institutional, and moral perspectives, targeted strategies are proposed to address ethical issues related to intelligent robot technology. Read more →
