Exploration of the emotional problems in the process of English learning can promote the emotional communication between teachers and students. The organic combination of the two aspects of cognitive and emotional can help to finish the promotion of cognitive and education with emotion. People abroad have achieved many results about the research, while further research in domestic is still rare. This paper mainly analyzes the main emotional problems influencing the English leaming, clarifies the importance of using emotional strategy in English learning, points out the way of improving learning effect by affective strategies, thus to guide the students form the corresponding emotion strategy, effectively use in English learning, and improve the English learning.展开更多

For this purpose, we study the effects and electronic state densities of atomic hydrogen and nitrogen in pure tungsten, in order to analyze some important properties such as the density of states of the system. Focusing on this application, this work is a preliminary study of the behavior of atoms of hydrogen and nitrogen, on a surface of tungsten on the three sites of the cell： top, hollow and bridge. We use a program simulation based on the DFT （density functional theory） implemented in the Open-Source Code Quantum Espresso, in order to obtain the adsorption energy and the density of states of the systems.展开更多

The numerical results show that the polarization and Curie temperature will both become large sensitively due to the large values of JB and the small value of ΩB of the defect layers. Meanwhile, the dependence of the crossover values of the exchange interaction JA, the transverse field ΩA of the bulk material on the exchange interaction JB and the transverse field ΩB of the defect layers are shown in 3-Dimensional （3-D） figures for the first time.
