After the engineering and technical personnel reasonably use BIM science and technology, not only can the architectural design of cold source project be more optimized, but also the accuracy of central air conditioning load can be improved, thus ensuring that HVAC central air conditioning buildings can play their due functions. Therefore, the construction unit and its related personnel must strengthen their knowledge and understanding of BIM science and technology, and make effective use of it in modern HVAC engineering construction. Modern HVAC technology can adjust indoor and outdoor air temperature appropriately and purify indoor air effectively, thus creating a more comfortable indoor environment for the people. At present, the previous construction methods have not met the requirements of modern HVAC construction specifications. However, there are still three problems in the installation of HVAC, namely, inaccurate construction drawings, unsmooth chilled water pipe system of air conditioners, and lax management of central air conditioners.展开更多

These basic skills are also directly related to vocabulary, but many teachers report that the effect is not good. Compared with junior high school English, senior high school students have a large vocabulary, which is often difficult to remember, or words confuse memory, often forget, etc., so that students' vocabulary is difficult to meet the needs of learning and English teaching effect is not good. In view of this situation, teachers should pay attention to guide students to learn and remember the rules, improve students' vocabulary, and then improve the quality of English teaching. According to the rules of time, quantity and association, the teacher guides the students to memorize the words and promotes the students to learn the words.展开更多

In addition, in addition to the design of the main structure of the early building, the decoration design and construction in the later stage is very important, and it is no exaggeration to say that the decoration construction is the most critical stage to determine the function and performance of the building. With the continuous development of the construction industry, the construction technology is also constantly improving and the new materials and new technologies applied in the field of architectural decoration design are also becoming more and more common.

As early as 1970s and 1980s, China began to vigorously develop the mining industry, among which the excavation of Daqing Oilfield is more famous, and it can still provide a steady stream of petroleum minerals today. In the past, some safety accidents often occurred in the process of mineral exploitation projects, resulting in casualties and economic losses, which were a kind of loss to the society and the industry. The emergence of geological exploration technology for mineral exploitation made people hope to reduce the risk coefficient of mineral exploitation and improve the efficiency of mineral exploitation, and had an optimized direction. In this paper, the concept and application of geological exploration technology, as well as a series of problems and obstacles will be discussed, combined with examples of remote sensing exploration technology, hoping to provide some reference for future mineral exploration.展开更多

For teachers' teaching work, the network learning space is not only a change in teaching methods, but also a deeper change in teachers' educational concepts and thoughts. Using online learning space to optimize classroom teaching has also become a help to improve classroom teaching efficiency and teaching quality. However, the integration of education and information technology in our country is getting closer and closer, and the means and methods of learning by using network technology are becoming more and more perfect. With the help of information technology and network environment, the network learning space provides teachers and students with relevant technologies and services they need to meet the teaching needs.

Methods: This study focuses on evidence-based nursing care of severe acute pancreatitis. Patients with severe acute pancreatitis who received treatment in our hospital were selected, from which 80 cases were chosen for detailed analysis. The patients were randomly grouped into a control group (conventional nursing care) and a study group (evidence-based nursing care), with 40 patients each. Relevant research data were recorded during the nursing process, analyzed, and used as research indicators. Results: The hospitalization time and morbidity and mortality rate of the research group were shorter than those of the control group, and the recovery rate was higher than that of the control group (P < 0.05). Patient satisfaction with nursing care in the observation group was higher than in the control group (P < 0.05). Conclusion: For patients with severe acute pancreatitis, the use of evidence-based nursing methods effectively reduced the patient’s mortality rate, improved its curative effect, and also shortened the patient’s hospitalization time.展开更多
