Higher engineering education assessment is an important part of the existing education system assessment, it plays an important role in the strengthening macroeconomic management of higher education, the engineering education reform and development as well as improving the quality of engineering education. Especially with the international trend of(More)
In this paper, theoretical analysis and practical of coal production were combined to study the mechanism of large gas explosion accident at coal face. The author uses coal spontaneous combustion theory, as well as rock pressure, gas flow field and gas explosion theory to study the cause of the large gas explosion with high incidence at coal face.(More)
The stator end-winding is the key component of turbo-generator running in normal status. For exploring the quality characteristics for stator end-winding of large capacity turbo-generator of 600MW,the test modal based on architectural characteristics is established. The hammering method is used for testing process and the modal parameters of stator(More)
By analyzing the evaluation method and working characteristics of the design courses in universities, a fuzzy comprehensive evaluation method is advanced, which based on fuzzy clustering analysis. According to the fuzzy membership degree theory, the author translated the qualitative evaluation into quantitative evaluation. Through this, the problem that the(More)
In deep coal mine, the thermal pollution is becoming more and more serious. It is harm for the workers physical and mental health; and at the same time it has a serious impact on the normal production. In this paper, the research situation of the thermal pollution in deep was described; a number of commonly cooling techniques and methods are analyzed;(More)
