Abstract： Social essentialism is an intuitive theory about social categories. It is a biological attribution of differences in social categories. It implies that members of one social category share unobservable intrinsic characteristics that determine their membership and generate observable similarities between them. Studies show that social essentialism increases racial, gender, and class prejudice, but also reduces prejudice against obese people, homosexuals, and criminals. Why are there domain differences in the impact of social essentialism on prejudice? The causal discounting theory holds that people weigh the possibility of multiple candidate causal explanations perceived in the process of explaining group differences. When a given causal explanation is considered more likely, other causal explanations are automatically regarded as unlikely, that is, the possibility of alternative causal explanations is discounted. The causal discounting theory, however, fails to distinguish between social categories that promote prejudices and those that reduce prejudices, nor does it explain the internal logic of causal discounting in a process of social essentialism that leads to different prejudice outcomes. Attribution theory can provide further insight into these questions.牋Specifically, a major difference between social categories is whether group members are able to join or leave them. Based on this criterion, social categories can be classified into two categories: forced social categories and chosen social categories. Forced social categories result in significant social status differences between groups, and people often need to explain why one group has a lower status than another. However, in the chosen social categories, the stigma of groups is more prominent, so it is often necessary to explain why a group holds a stigmatized identity. More importantly,in forced social categories where stability cues are strong (e.g. race, gender, and class), social essentialism leads people to believe that differences between groups are difficult to change, thus increasing prejudice by discounting environmental explanations. In chosen social categories where controllability cues are strong (e.g. obesity, homosexuality, criminals), social essentialism leads people to believe that the stigmatized identities of some group members are uncontrollable, thus reducing prejudice by discounting chosen explanations. 牋 Future research on social essentialism could focus on the following aspects in order to yield more practical value. Firstly, it is necessary to clarify social essentialist beliefs, describe how each component relates to prejudice, and analyze these relationships across different social domains in order to gain a deeper understanding. In addition, future research should examine the mechanisms behind social essentialism's influence on prejudice in greater depth. It is mainly because social essentialism's influence on prejudice can be complex, and it will not increase or decrease prejudice on its own; also, the current research on this mechanism is primarily based on causal discount theory, so future research should examine the internal mechanisms of this effect in greater detail. Finally, future research should focus on developing practical and effective interventions that can maximize the positive effects of social essentialism while eliminating its negative effects. The main reason for this is that these interventions are helpful in reducing intergroup conflict, eliminating prejudice, and fostering harmony in society. In order to reduce prejudice in the future, there needs to be vigorous development of relevant and effective intervention programs that target social essentialism.

Abstract： With the promotion of the construction of ecological civilization in China, the demand for professional talents with ecological background is also urgent. How to improve the teaching quality of ecology and explore new teaching models are the problems that ecological educators need to solve. Based on years of teaching practice and in combination with the new talent training objectives, our teaching team has formed a teaching mode of "taking the cultivation of comprehensive quality as the core, ecological civilization as the principal line, supplemented by a variety of teaching tools, and integrating a variety of teaching modes", which focuses on the guidance of values system while imparting knowledge. This teaching reform has played a positive role in improving students' interest in learning, cultivating students' autonomous learning ability, teamwork ability, etc.

Abstract：
Social essentialism is an intuitive theory about social categories. It implies that members of one social category share unobservable intrinsic characteristics that determine their membership and generate observable similarities between them.There are numerous studies showing that social essentialism contributes to prejudice based on race, gender, and class. but also reduces prejudice against obesity, homosexuality and criminals. In forced social categories where stability cues are strong (e.g. race, gender, and class), social essentialism leads people to believe that differences between groups are hard to change, thus increasing prejudice by discounting environmental explanations. In chosen social categories where controllability cues are strong (e.g. obesity, homosexuality, criminals), social essentialism leads people to believe that the stigmatized identities of some group members are uncontrollable, thus reducing prejudice by discounting chosen explanations. For future research, it would be useful to examine how social essentialist beliefs emerge, develop and ultimately lead to different outcomes, and from there, to develop systematic, sustained, and effective interventions aimed at eliminating prejudice and promoting harmony within society using scientific psychological solutions.

Abstract：本文针对某汽车供应商提供的Cu-Ni-Cr镀层试样，采用电化学方法(电化学阻抗、动电位极化曲线)，研究了不同钙铁离子浓度以及在特定温度下铁离子对Cu-Ni-Cr镀层耐蚀性的影响。研究结果表明，在浸泡初期Ca2+对Cu-Ni-Cr镀层起钝化作用对镀层具有一定防护作用，在浸泡中后期，主要以Cl-的腐蚀作用为主；Fe3+对Cr为加速腐蚀作用，而且随着温度升高会加速Cr的腐蚀，Fe3+对Cu-Ni-Cr镀层的腐蚀反应主要发生在Ni-Cr层。
