Research and Analysis of Production and New Capacity of China's Electronic Copper Foil Enterprises in 2017

In the light of current fast development of new and expanded copper foil projects of electronic copper foil enterprises and recent adjustment of the main copper foil categories set to be developed by some companies(generally from lithium foil to PCB foil).The secretariat of China Electronics Materials Industry Association e-copper foil branch conducted in March,2017 an extensive and in-depth

Study on stability of road and bridge based on stress analysis and computer modeling

In this paper, some concepts and problems in the stress analysis design method are discussed. Based on the introduction of various types of stress characteristics, the differences between stress decomposition and stress classification are emphasized. We pointed out that the stress decomposition only relates how stress is decomposed into uniform stress, the equivalent stress distribution of linear and nonlinear stress components, how will break out of stress classification, entirely by the stress position and stress the external decision. At the same time, it also gives a valuable perspective on the distribution twe ofoeak stress, the self limitation and the stress decomposition and classification.

Research on Financial Internal Control of Higher Vocational Colleges

Financial intemal control in higher vocational olleges is an important means to ensure the stable development of school finance.However,in practice,it was found that there are problems such as insufficient internal supervision,imperfect internal control system,and imperfect risk prevention mechanism.Therefore,this article aims to discuss the relevant overview,existing problems,and specific strategies of financial intermal control in higher vocational colleges to provide a reference for the improvement of financial internal control in higher vocational colleges.

Application of data analysis method in geotechnical engineering

Geotechnical seismic engineering belongs to the cross field of geotechnical engineering and earthquake engineering. Due to the dual effects of the variability of geotechnical objects and the complexity of dynamic loading, the scientific problems involved in this field have to face more uncertainties. Through the analysis on the status quo of uncertainty analysis methods in geotechnical earthquake engineering in the field of non deterministic analysis clear difficulties, weak links with all kinds of uncertainty analysis method to solve the inherent weakness of determining geotechnical earthquake engineering uncertainty problem, and can determine the establishment and improvement to provide some ideas and direction analysis model for non.

The Research of thick seam mining methods

China＇s total coal reserves are enormous, in which recoverable reserves of coal seam thickness ofmineable coal reserves in China accounted for 43% of recoverable reserves When correctly using thick seam mining, mining methods can improve the proper thick seam mining rate and reduce coal loss. Using proper thick seam mining method can effectively reduce the thick seam mining costs. In mining safety, the use of appropriate thick seam mining methods can effectively prevent thick seam mining accidents. But in the process of development and current situation from the perspective of the Chinese coal mining, there are certain aspects of thick seam mining problems. These problems are mainly in the thick seam mining and the coal recovery rate is low, resulting in lots of waste coal. Besides, thick coal mining is less secure, safe and there are frequent accidents. These problems have seriously affected the thick seam mining. And a lot of thick coal seams of coal resources can not be effectively taken out. Now Chinese mining methods in thick seam mining areas are mainly open-pit mining and underground mining exploitation. Because of the open-pit coal burial depth has more stringent requirements, only used in shallow-depth areas. Underground mining is the primary way China is now using in thick seam mining. Underground mining methods include full-height slice mining and mechanized mining caving mining method once adopted. Research on these thick seam mining methods can provide theoretical and technical support for thick seam mining, thick seam mining techniques to enhance the level . I will combine the current situation of thick seam mining in Chinese study with thick seam mining methods, comments and suggestions for the current thick seam mining study

Researches on the teaching based on the applied linguistics

Along with the development of the times and the innovation of the society, the history and cultures are also constantly inherited under the strike of the flow of the tide over the years, forming the centuries-old cultures. Of course, the heritage of any culture needs a carrier, and the history and culture is no exception. Language itself is a kind of tool for the information exchange, and the communication process of the language is also accompanied by the substitution of the culture. So it can be said it is not only the category of the information exchange, but should be expanded to the cultural heritage. With the continuous changes and development of the society, people focused more on the application in the learning of the language, so as to highlight the characteristics of different cultures through the applications in different aspects.

Investigation fbr teaching mode of developmental biology

The reform of teaching mode, arrangement of curriculum content and investigation for relevant theory can promote the development of the biology course, and can greatly improve the research value of developmental biology. Based on this, this paper will analyze the course content, the teaching mode and the content of multimedia courseware by combining with content of developmental biology.
