From the objective point of view, the computer technology in play its advantages at the same time, once the use of unscientific, will also form a certain negative impact. Therefore, it is necessary to discuss the computer technology from many angles
Study on Performance Control of Intercalated Melt-Blowout Method Based on Least Nonlinear Squares
Get PDFIn this paper, the performance control of intercalated melt-blown nonwoven materials has been studied in many aspects. According to the different indexes given by the title, a model has been established to analyze the change rule of structure variables and product performance of intercalated melt-blown nonwoven materials and the influence relationship of different indexes, and the model has been verified. For the research on the change law of structural variables and product performance, we first preliminarily analyzed the change law of structural variables and product performance after intercalation through data visualization, and studied the change ratio of six indicators. The primary objective of the model is to study the dependence of the intercalation rate on the six indexes. Then we study the influence of the intercalation rate on the change ratio of the three indexes, namely porosity, compression and resilience, and filtration resistance, through correlation analysis. Studies on the relationship between process parameters and structural variables, we after data processing on multiple correlation analysis of the dependent variable and the correlation coefficient between different independent variable indicators, and then by the least squares fitting receiving distance, air velocity and thickness, porosity, compression resilience, the relationship between the use of the relationship developed predict eight parameters combination structure of the variable. Finally, we use simulation data to verify the practicability of the model and the effectiveness of the algorithm, solve the problem of intercalating melt-blown nonwovens performance control, so as to improve the efficiency of the processing and weaving system, maximize the use of resources. And analyze the advantages and disadvantages of the model, explore the significance of promotion and reference

and paper reading seminar writing, and how to build an evaluation mechanism for the management of the entire teaching process, so as to
achieve equal emphasis on basic theory and cutting-edge research, theoretical teaching and practical training, to enable graduate students
to truly understand and master theoretical knowledge, improve their practical ability, and lay a solid foundation for scientifi c research and
subsequent innovation
Research on online public opinion response and Strategy of University Emergencies under new media environment
Get PDFNew media environment not only brings convenience to people’s life, but also brings great infl uence.In the network public
opinion events, university emergencies account for a large proportion. University emergencies not only have a direct impact on university
teachers and students, but also bring a lot of adverse eff ects on the regular teaching activities of universities and colleges, and also bring
severe challenges to the emergency management of network crisis events in universities and colleges. In line with the development trend
of new media, the study of online public opinion responses and strategies of university emergencies plays a vital role in improving the
management ability and level of the university, ensuring the stable conduct of various education and management of the university, and
maintaining the stability of the university and the society.This paper mainly studies the characteristics and coping strategies of online public
opinions in college emergencies under the new media environment, including the basic situation of existing online public opinions in college
emergencies, the characteristics of online public opinions in college emergencies under the new media environment, the actual problems
existing in online public opinions in college emergencies and the specifi c coping strategies
Research on mixed teaching practice of medical immunology
Get PDFwith the rapid development of information technology, hybrid teaching mode is applied. As an important part of basic
medicine, medical immunology is relatively abstract. If teachers still use traditional teaching methods, it is diffi cult to ensure that students
understand medical immunology thoroughly. At this time, teachers can use mixed teaching to teach students professional knowledge,
which can not only make the teaching atmosphere more interesting, but also ensure that students understand the knowledge points taught
by teachers thoroughly, so as to improve the quality of teaching activities. In this regard. This paper studies the mixed teaching practice of
medical immunology for reference
Multiple Sound Sources 3D Localization System Using TDOA and Tetrahedral Microphone Array
Get PDFIn this paper, we propose an acoustic positioning and tracking system using time difference of arrival (TDOA) for multiple sound source positions in a three-dimensional (3D) space. The microphone array uses a regular tetrahedron structure and only requires four sensors to realize the position analysis of the sound source. We develop a fast cross-correlation algorithm to obtain characteristic peaks quickly from the TDOA data, which can effectively distinguish the phases of different sound sources and locate them in a multi-source environment. The optimized TDOA algorithm uses a minimum number of 3D sound source capture sensor arrays, which can capture the 3D coordinates of every sound source while performing low-latency multiple signal classification (MUSIC) calculations. The development of this technology will have a wide range of applications in real-time sound source coordinate acquisition in the field of multi-source acoustic visualization

Near-infrared fl uorescence probe based on selective recognition of glutathione
Get PDFGlutathione (GSH) is an important bioactive molecule, and its content is closely related to the stability and health of the
intracellular environment. Therefore, the detection of GSH is of great signifi cance for life science research. Near-infrared fl uorescence probe
can eff ectively avoid fl uorescence quenching and enhance fl uorescence signal, so it is often used in the detection of GSH. In recent years,
the development of near-infrared fl uorescence probes has been rapid, and several series of near-infrared fl uorescence probes have been
reported for the detection of GSH. Based on this, a new type of NIR fl uorescence probe was designed and synthesized in this paper. Through
its recognition with glutathione (GSH), the fl uorescence of the probe was enhanced after reaction with glutathione. Because the probe has
selective recognition of GSH, high sensitivity and certain biocompatibility, it can be used for the detection of GSH content in vivo

No full textafter entering xinshida, the fi eld of cross-border e-commerce has fl ourished, providing an important driving force for the
economic growth of various countries, but it is still a complex that is constantly supplemented, continuously improved and needs to be
developed, requiring a large number of professionals to innovate and adjust the operation platform and mode. Colleges and universities
should pay more attention to the “quality” and “quantity” of talent training when carrying out the training of cross-border e-commerce
innovative and entrepreneurial talents, so as to provide talent support for the healthy and sustainable development of cross-border e-commerce.
Based on this, this paper analyzes the demand for cross-border e-commerce talents, and puts forward some practical strategies, in order to
provide reference for the cultivation of cross-border e-commerce innovation and entrepreneurship talents
