Anyone who works on the college ideological and political education has to learn the basic features of the development of the undergraduates’ moral qualities as well as the counseling principle, the optimism principle, the democratic principle and the encouraging principle. The college applied the means of traditional moral education to enhance undergraduates’ understanding of morality, gave topics on morality for undergraduates to increase their judgments on moral issues, praised the moral model undergraduates who served as a role model for the undergraduates, and offered the literary and artistic works for reading to trigger the emotional response of undergraduates. The undergraduates will have a better ideological understanding and seek new heights of self-cultivation during their moral practice.展开更多

Integrity is a distinct characteristic of Marxism. Research and grasp the integrity of Marxism is the level one discipline of Marxist theories, especially the Marxism basic principle. Basic principle of Marxism is not exceptional and also of course, the theory of Marxism is its logical premise. People＇ s life is to continue and develop which makes this kind of complex internal structure to establish contact with the outside world. Our research is novel and innovative which will be meaningful for the research of the Marxism theory.展开更多

Thus, its understanding implies an assumption at a conceptual-theoretical level of some approaches where the didactic aspects find their usefulness by relating to value principles. This situation expresses in fact focus on the formative side specific to the process of didactic communication. Therefore, the understanding of the didactic principles emphasizes concrete modalities of completing the educational activities.展开更多

文摘Zinc-air batteries(ZABs)are promising energy storage systems because of high theoretical energy density,safety,low cost,and abundance of zinc.However,the slow multi-step reaction of oxygen and heavy reliance on noble-metal catalysts hinder the practical applications of ZABs.Therefore,feasible and advanced non-noble-metal elec-trocatalysts for air cathodes need to be identified to promote the oxygen catalytic reaction.In this review,we initially introduced the advancement of ZABs in the past two decades and provided an overview of key developments in this field.Then,we discussed the work-ing mechanism and the design of bifunctional electrocatalysts from the perspective of morphology design,crystal structure tuning,interface strategy,and atomic engineering.We also included theoretical studies,machine learning,and advanced characterization technologies to provide a comprehensive understanding of the structure-performance relationship of electrocatalysts and the reaction pathways of the oxygen redox reactions.Finally,we discussed the challenges and prospects related to designing advanced non-noble-metal bifunctional electrocatalysts for ZABs.

Anyone who works on the college ideological and political education has to learn the basic features of the development of the undergraduates’ moral qualities as well as the counseling principle, the optimism principle, the democratic principle and the encouraging principle. The college applied the means of traditional moral education to enhance undergraduates’ understanding of morality, gave topics on morality for undergraduates to increase their judgments on moral issues, praised the moral model undergraduates who served as a role model for the undergraduates, and offered the literary and artistic works for reading to trigger the emotional response of undergraduates.
