In recent years, the development momentum of China's construction field is good, and various construction projects are increasing, creating a good living space environment for people. In order to meet the needs of wartime, the construction of civil air defense basement is very necessary. Compared with the general construction engineering projects, the construction requirements of civil air defense basement are higher, in terms of technical application standards are obviously higher than ordinary buildings, especially in structural design has more requirements, in the actual civil air defense basement structure design process, often appear a variety of problems, seriously affect the functional role of civil air defense basement, not conducive to the development of civil air defense engineering. The continuous acceleration of urbanization process has made the development space of urban ground buildings smaller and smaller, underground buildings have begun to be paid attention to underground construction projects must involve basement structures, the safety of basement structures is directly related to the quality and safety of the entire building, and the civil air defense basement structure introduced in this article has higher requirements than ordinary basement building structures. This article analyzes this and puts forward several simple points, which should be seriously solved to ensure the function of the civil air defense basement.

The transportation capacity pressure and the high technological content of rail transit equipment make safety control problems potentially disastrous. These challenges elevate demands for the development of intelligent technology in the field of rail transit operation and maintenance, allowing significant room for growth and development in the industry. This paper reviews the current status of intelligent operation and maintenance by discussing the intelligent operation and maintenance detection of locomotives and the electric locomotive technology state management platform in rail transit. Through an analysis of locomotive operating data acquisition, the architecture of the intelligent monitoring and maintenance system, key factors affecting fault diagnosis and remote operation and maintenance, and intelligent operation and maintenance systems, this paper summarizes the current state of intelligent operation and maintenance.

With the development of railway technology, railways in alpine regions are gradually being constructed. Different from ordinary high-speed railways, alpine high-speed railways have higher construction costs, higher operation and maintenance technologies and costs, and their dispatching and commanding is also difficult. This paper will discuss the operation of the alpine high-speed railway from the perspective of the safe operation and dispatching of the alpine high-speed railway.With the improvement of people's living standards and the advancement of science and technology, alpine high-speed rail is an important form of railway transportation, and we need to conduct in-depth research on its safe operation and dispatching command. The safety operation and dispatching command system of high-speed railways in alpine regions is a high-risk system with a rather complex structure. Analyzing and managing its safe operation, dispatching and commanding can effectively enhance the management effect of railways, strengthen safety, operation and research on dispatching command can effectively promote the development of railways and better serve the people.

In recent years, with the development of science and technology in China, modern intelligent conferences have been widely used in people's work and life. Select highly intelligent, high-tech products, establish an open architecture of the system, and take standardization and modularization as the design requirements, which are not only convenient for the management and maintenance of the system, but also can maintain the advanced nature of the system for a long time. We will closely focus on the implementation of the above content, in line with the three principles of advanced, reliable stability, economic rationality, in strict accordance with the technical indicators and functional requirements, in accordance with the relevant national standards, for the modern intelligent video conference system composition research and analysis. It is hoped that this research can help people further understand the advanced aspects and technical composition of modern intelligent video conferencing, and promote the continuous development of intelligent technology in China.

This paper investigates the application of bistatic Synthetic Aperture Radar (SAR) technology in the analysis and optimization of rocket motion within the equatorial plane. Bistatic SAR is an advanced remote sensing technology that enables the precise measurement of the position and velocity of objects, including rockets. By incorporating bistatic SAR data, we aim to provide a comprehensive and in-depth understanding of rocket motion under various scenarios and parameters. We first study the basic motion equations of the rocket under the influence of pure gravity and Earth’s rotation, introducing the concept of Coriolis force. Subsequently, we conduct a detailed analysis of the rocket’s dynamics, including factors such as thrust, lift, and drag, as well as their impact on the rocket at different stages. We also discuss the motion differential equations during the rocket separation process, focusing on the dynamic characteristics of the Musk-style rocket during the first stage separation and return landing. Throughout the derivation process, we employ multiple assumptions and parameters, making the rocket’s motion differential equations more complex and thus closer to actual situations. The integration of bistatic SAR technology with the rocket’s motion analysis provides a novel approach to improving rocket performance and navigation capabilities.

With the deepening of China's aging population, the number of assisted care facilities for the elderly have increased. However, the spatial model of pension facilities and the setting requirements of the intermediary and nursing unit are not perfect, leading to a series of problems such as the lack of design guidance of the intermediary and nursing unit in most pension facilities, the unreasonable proportion of supporting facilities space. This paper sorts out and summarize the relevant norms and actual cases of care-type elderly facilities in Japan, Germany and the United States, where the elderly system is well developed, and focuses on the spatial design of the elderly rooms in the three countries, exploring the common de-sign points of the elderly rooms in terms of usable area and room size, and summarizing the spatial strategies and methods of care-type elderly facilities. By summarizing and learning foreign experience, we can further improve the standardization level of the construction of elderly care facilities and provide reference for the design and improvement of elderly care facilities in China.
