This paper is to analyze the connotation of network security literacy by conducting a questionnaire survey on the level of college students' network security literacy. It analyzes the data in detail from four sub-dimensions: network security awareness, network security knowledge, network security skills, network security law and ethics. According to the analysis results, it provides reference for the improvement of network security literacy level of college students.

The control logic of single elevator and the control method of multi-elevator cluster were studied based on DPRO elevator simulation training model, and the control algorithm of elevator cluster was optimized with the goal of minimizing the waiting time of passengers. The automatic control system of elevator cluster is designed by Siemens S7-1200 PLC, and the program of elevator cluster control system and the monitoring screen of upper computer are written by TIA Portal software. The automatic control and real-time monitoring of running state of six elevators cluster are realized. The simulation results show that the improved system can effectively reduce the average waiting time of passengers. And improve the overall working efficiency of the elevator group.

AGV is the key equipment for the flexible and intelligent modern logistics system. This paper mainly designs the system of magnetic navigation AGV, including structural design and control system. In the structural design, the differential steering six-wheel running mode is adopted, and the three-dimensional design software is used for the modeling design. The control system adopts the MCU as the control unit. Based on the magnetic navigation, the fuzzy control is used to realize the driving speed adjustment to ensure that the AGV runs on the predetermined trajectory, so that the AGV has strong stability, fast response speed and automatic correction in the work. Ability. Finally, the corrective ability of the AGV is verified by simulink simulation.

In order to well know the current situation of atmospheric environment in Jilin City, correlation analysis method and applied statistical method were used to analyze the change characteristics of air pollutant mass concentration, and the correlation between pollutant concentration and meteorological factors, based on the monitoring data of CO, SO2, NO2, O3 (O3-8h), PM2.5 and PM10 from 7 ambient air quality monitoring stations in Jilin City from 2014 to 2018, and hourly meteorological data in 2018. The results show that: from 2014 to 2018, the annual average concentrations of SO2, NO2, PM10 and PM2.5 has showed a downward trend, while the concentration of O3 has been increasing in Jilin City, the concentrations of PM10, PM2.5 and O3 were occasionally higher than the national standard, indicating that they are the main air pollutants in Jilin City; the pollutant concentration varied from seasons, months and times, therefore, stagger production time according to the change law can improve ambient air quality; meteorological factors were correlative with pollutant concentrations, in which O3 concentrations was highly correlated with temperature, humidity and wind speed, and NO2 was highly negatively correlated with wind speed; the importance of meteorological factors to concentrations of CO, NO2, O3, PM10 and PM2.5 displays wind speed > atmospheric pressure > humidity > temperature; precipitation can reduce the concentration of PM10 and PM2.5, and the reduce effect was more obvious with increasing precipitation. The results of the current study can provide the data support for a further study of air pollution control and environmental capacity in Jilin City.

Today's world is a highly competitive era for network application development. Accurate, economical and efficient development and application are the needs of the times.The design pattern of MVC architecture is widely used in the design of application systems at present. based on MVC framework, this paper optimizes the traditional MVC design pattern by using Spring boot framework and the concept of "Convention is better than configuration".  Solve the limitation of traditional MVC design pattern.

Material Safety Data Sheets（MSDS）has become an important means of chemical safety management in universities. This paper introduces the concept of MSDS and its content in detail. In order to ensure the safe use of chemicals in university laboratories, it is suggested in this paper that universities control strictly the process of the purchase, use and waste disposal of chemicals considering the current situation of universities featured by chemical engineering.

Lu Xun's novel On the Restaurant has left a deep impression on the readers because of its description of Lvweifu's " perfunctoriness", "vagueness", and "exceptionally slowness". Why does Mr. Lu Xun give such a description? What is the background? For this reason, this article puts the Lvweifu's description of the spirit and action into macro social and cultural context, uses Bourdieu cultural sociology as a theoretical support to analyze the martial arts spirit from three core aspects: field, habits and capital. It is believed that the gradual loss of martial arts spirit is the prominent appearance of the social value of the intellectuals' represented by Lvweifu at that time. This appearance is the profound influence of the intellectual spiritual entities in the field, capital, and habits caused by the dramatic social changes in the late May 4th period. The central problem of qualitative change, It is embodied in deep social relations with the field(social space), habits(subjective behavior), and capital(objective behavior). This deep social relationship directly affects the "convergence of the martial arts spirit", resulting in the intellectual' "perfunctory", "vague" mental state and "exceptionally slow" action represented by Lvweifu, and eventually affected the intellectual reform.

As the antithesis of politeness studies, the study of impoliteness becomes a hot spot in pragmatics. In this paper, Bousfield's impoliteness theory is used as an analytical foundation to study the impolite expressions of dialogue in the classic fantasy film Harry Potter and the Sorcerer's Stone. This paper focuses on the following two research questions: 1, how direct and indirect impolite discourses are distributed in movie dialogues; 2, what are the prominent forms of the two discourses. Meanwhile, the author further analyzes the different characteristics of the film characters through the film dialogue in the impolite words.

With the acceleration of globalization, supply chain has gradually extended from the coordination between internal and external enterprises at the micro level to the promotion of industrial chain and value chain at the macro level, and even the improvement of the performance of the whole national economy. Chemical industry is one of the five pillar industries in Jilin Province, but its industrial advantage has been weakening in recent years. From the perspective of modern supply chain, the paper found the problems in the development of chemical industry supply chain in Jilin Province, and tried to put forward the integration path and innovative development suggestions for the chemical industry supply chain in Jilin Province, so as to provide strategic reference for the realization of value chain climbing in the new development pattern of chemical industry in Jilin Province.
