A ＂shared＂ relationship between teachers and students is advocated now. In the construction of a harmonious relationship between teachers and students, the positions of the teachers and students in teaching should be first made clear, and then an effective mental communication between teachers and students is necessarily available.展开更多

The current state of BF ironmaking in Europe, America, Japan, and China were briefly overviewed. Moreover, some innovative BF ironmaking technologies aiming at environmental harmony and operation intellectualization in the world, such as waste gas recycling sintering, BF op eration with coke oven gas injection, ferro coke, lime coating coke, BF visualization and intellectuali zation, were roundly summarized. Finally, some discussion on the technologies was carried out and the development trends of BF ironmaking were pointed out. The review could provide references and supports for the progress of environment friendly technologies of BF ironmaking, thereby promoting their practical applications and achieving sustainable development of BF ironmaking, especially for Chinese ironmaking industry.展开更多
文摘The harmony of a relationship between teachers and students is a powerful promotion to the students＇ mental health. A ＂shared＂ relationship between teachers and students is advocated now. In the construction of a harmonious relationship between teachers and students, the positions of the teachers and students in teaching should be first made clear, and then an effective mental communication between teachers and students is necessarily available.
