The temperature extent of linear resistance, non-linear deviation and endurance ability of surge energy were further discussed. The effect of Mg^2+, AI^3+ and Si^4+, which could be solid solutioned in ZnO grain and the function of Y^3+ ion segregated out in grain boundary were studied as well. The function of Ti was analyzed emphatically.展开更多

To carry out English teaching in a scientific and reasonable way is of great significance to the cultivation of primary school students' core qualities such as language ability, cultural awareness and learning ability. Using English picture books to carry out reading teaching is a new trend in English teaching in recent years. There are many stories with complete context in English picture books. Using these stories to carry out English teaching can on the one hand stimulate students' interest in learning English, and on the other hand help students get more language input. In view of this, it is very necessary to promote the integration of primary school English picture books reading and main textbooks. Therefore, based on my own teaching experience, the author explores the strategy of integrating English picture books with main textbooks in order to provide theoretical basis for primary school English teachers' teaching.展开更多
