Abstract.Because the shallow water effect and shore wall effect have significant influence on the ship's hydrodynamic force during the movement of ship in and out of the ship lift car, the operation process of the ship lift at this stage is more complicated and there are many influencing factors, which is one of the core links of the safe operation of the ship lift. Therefore, based on domestic and foreign research data, this paper analyzes and summarizes the types of ship lift and the hydrodynamic characteristics of ship lift during the phase of ship entering and exiting the car, and summarizes and … Read more →

Abstract.With the rapid development of information technology, data communication and management systems are becoming more and more important in various industries. Especially in remote device management and data center operations, effective data processing and transmission mechanisms are crucial to ensuring system performance and reliability. In this context, serial port virtualization technology is particularly important because it allows remote devices to be controlled and monitored over the network, so that physical location constraints are no longer an obstacle to efficiency and effectiveness. … Read more →

Abstract.Mg is one of the essential medium elements for plant growth and an essential mineral nutrient in agricultural production. In this paper, we summarize the past series of plant Mg nutrition studies and Mg leaching tests in field soils to reveal the leaching status of Mg elements in soils today and their influencing factors. According to the test results of 325 609 soils in the 2016 National Soil Testing and Formulation Program, Mg-deficient soils with exchangeable Mg content (Mgex) <50 mg-kg-1 accounted for 43.8% of soils in the country; among them, soils with 25-50 mg-kg-1 accounted for 7.64%, … Read more →

Abstract.Thematic meaning inquiry provides a new way of thinking and direction for English reading teaching. The degree of exploring the meaning of the theme influences the depth of students’ discourse comprehension, the height of students’ thinking development and the effect of students’ language learning. Combined with senior high school English teaching cases, this paper discusses how to explore the thematic meaning through in-depth interpretation of texts. Under the guidance of the activity-based approach to English learning, this paper expounds an effective approach to reading teaching design … Read more →

Abstract.Concrete is one of the most widely used building materials in the world. The compressive strength of concrete is a crucial parameter in construction engineering as it directly affects the safety performance and stability of building structures. Therefore, accurately predicting the compressive strength of concrete has become a widely discussed issue across various fields. Both traditional prediction methods and machine learning techniques, which have gained popularity in recent years, play important roles in this field. Researchers have started applying these methods to predict the compressive … Read more →

Abstract.With the acceleration of China's economic development and urbanization, people's demand for convenient transportation is increasing, of which the most representative is highway construction. But the project compared to other projects there are many difficulties and uncertainties, such as long construction period, large investment, complex technical requirements and other external factors. Among them, the construction unit on-site quality management is the top priority of engineering construction, so the construction unit how to comprehensively and accurately control and improve on-site quality … Read more →
