The new International Center for Dielectrics Research at Xi'an Jiaotong University: Recent activities and results

Abstract

This paper aims at some problems that the management of graduate education is facing. Combining with the discipline construction, we carried out some attempts and researches on improving the quality of graduate students' recruitment and training practice for different disciplines, and generalizations, which based on the educational practice of graduate students at School of Aerospace, Xi'an Jiaotong University. The present work is a try for combining with the discipline features to improve the quality of graduate education. Graduate Education in China and the Discipline Present Situation and Existing Problems of Graduate Education Since the setting up of degree system in 1981, there were 4.26million master graduate students and 490,000 doctor graduate students which were trained in China [1]. By the end of 2014, the number of graduate students in China is 1.85million, of which the master graduate student 1.54 million people, a doctoral candidate at 310,000 [2]. It has become a great nation of graduate education in China. However, with the rapid expansion of scale of graduate students, the problems existing in the recruitment, training, etc. became progressively. Firstly, the increase of graduate student recruitment lacks on the investigation of the depth of the society and the market demand, and brings excess caused part of the professional talents, employment difficulty [3]. Secondly, to supervise and guarantee the process of graduate student training mechanism is not sound, and the quality of master graduate student training is not high. The figures show that the elimination rate of master graduate student is less than 5% in China, which is as high as 30% ~ 50% in developed countries. This situation of easy enrollment and easy graduation lowers the level of master degree [1]. Finally, the training talents are lack of international competitiveness, because of the slow internationalization of graduate education in China [3]. The Relationship between Graduate Education and Discipline The meaning of university discipline has become more than a pure academic concept, that has a certain administrative function and bears three functions which are the talents cultivation, scientific research and social service, based on academic or research area classification. The meaning of university discipline construction includes the tutor team construction, scientific research and technological innovation, personnel training and construction of foundation platform [4]. Graduate education is to train high-level talents to adapt to the social needs, which is measured by the quality of training talents [5]. Therefore, discipline is the basic unit of graduate education, and graduate education is the important connotation of discipline construction. The level and the feature of discipline determine the cultivation model of graduate students and professional quality, and graduate students grow in characteristic of discipline [6]. 135

Preparation and Thermal Decomposition Mechanism of Sr²⁺-Doped Mg,Al-Hydrotalcite Nanocrystalline

“…Raman analyses show that there are two characteristic peaks from 150 cm -1 to 750 cm -1 for the Sr 2+ -doped samples (see Fig. because the growth direction of the Mg,Al-hydrotalcite nanocrystalline tends to be favorable to the direction which is parallel to the positively charged basic layer [3], the growth of Mg,Al-hydrotalcite nanocrystalline were restrained after Sr 2+ doping. Accordingly, the crystal size of the Mg,Al-hydrotalcite with Sr 2+ doping becomes smaller than that of ones without Sr 2+ doping.…”
