In recent years, the development of new media has brought favorable opportunities to the means of ideological and political education, colleges and universities should attach importance to the advantages and conveniences brought by it. Based on this, first of all, the characteristics of new media were outlined in this study, and the current situation of the use of new media in contemporary ideological and political education in Colleges and universities was analyzed by taking micro-blog as an example;then the opportunities and challenges that the current new media environment brings to the ideological and political work were studied;finally, the methods and means for improving the efficiency of ideological and political education were put forward. While paying close attention to the negative impact of the new media environment on ideological and political education, colleges and universities should also take effective measures to do ideological and political work well, so as to form a good state of development.

By means of electroless copper deposition method a complex image has been fabricated in a mixture of cupric sulphate and formaldehyde, the surface and subsurface properties of which has been studied in detail by X-ray photoelectron spectroscopy (XPS) combined with sputter depth profiling technique analyzing distribution and chemical state of copper and silver. Depth profiling by XPS in conjunction with Ar+ sputtering shows that the catalytic activity of silver persists, catalyzing reduction of copper. The integral areas of spectra Ag3d after electroless copper deposition for 5 min at different sputtering times demonstrate that the amount of silver at the surface is greater than that in the interior. And then, the quite likely reasonable explanations are provided for the result. Additionally, the chemical shift of Ag3d XPS and deconvolution of Ag3d XPS spectrum have been also analyzed respectively at length.

美国研究生教育最早源于殖民地时期学院颁发的荣誉性质的硕士学位。美国研究生教育形成受到美国建立本土大学的理想和德国大学的双重影响。19世纪上半叶,美国大学开始为大学毕业取得学士学位的毕业生开设学士后课程,这种高级知识学习成为美国研究生教育的开端。在研究生教育形成阶段,美国吸收德国培养研究生的经验,广泛采用德国大学的讲座制、习明纳和实验法,鼓励科学研究,同时抛弃德国大学"师徒式"研究生培养方式,在大学建立研究生院,把研究生教育与本科生教育结合起来,强调独立学习与科学研究是培养研究生的主要途径,研究生教育最终摆脱传统学院培养本科生方法的影响和局限,地位得以承认。研究生教育发展促进了美国研究型大学的产生和科学研究职能的确立。

A chemical process may involve multiple adiabatic electronic states, and non-adiabatic couplings play an important role in the reaction mechanism. In this work, the effect of non-adiabatic couplings in the H+MgH;→Mg;+H;reaction are studied using the time-dependent wave packet method and trajectory surface hopping method. The calculated results show that the reaction follows a direct abstraction process when the non-adiabatic couplings are neglected. However, when non-adiabatic couplings are included in the calculations, a longlived excited state complex(MgH_(2)+)*can be formed during the reaction. These direct and complex-forming reaction pathways are revealed by trajectory surface hopping *** non-adiabatic couplings induced complex-forming mechanism not only increases the reactivity but also has significant effect on the product vibrational state distribution.
