Abstract: 摘要: 在气质情绪特性理论框架下,编制《青少年儿童气质情绪特性问卷》,并对小学至大学共5831名学生的气质情绪特性进行调查。结果发现:问卷具有良好的信、效度;各学段女生情绪产生的速度都要快于男生;小、初、高三学段与大学阶段相比,情绪变化速度更快且更外显;本科生比专科生情绪更外显且更易控;文科生比理科生对情绪更敏感、产生强度更强、产生速度更快、变化速度更快且更外显。此研究为深入探索个体的情绪特征,拓展了新视野。
Abstract: Temperament is a controversial psychological construct and widely used in many fields such as childhood, adult, clinics, health and education. The current theories and its applications of temperament in our country overlooked the emotional aspects of temperament’s psychological characteristics. No measurement tool and no relevant research to emotional characteristics of temperament exist. As a result, we developed the questionnaire on children’s and adolescents’ emotional characteristics of temperament and administered it to children and adolescents in Shanghai. We enriched the connotation of the original “emotional excitability” of temperament, forming the six secondary indexes and named them as emotional characteristics of temperament. The six secondary indexes were as follows: (1) sensitivity of emotional excitability, (2) strength of emotional excitability, (3) generation speed of emotional excitability, (4) changing speed of emotional excitability, (5) controllability of emotional excitability and (6) explicitness of emotional excitability. These indexes were corresponding to the active characteristics of temperament. The connotations of these indexes were mentioned below: (1) Sensitivity of emotional excitability reflected people’s difficulty difference of emotion generation; (2) Strength of emotional excitability reflected people’s strength difference of generated emotions; (3) Generation speed of emotional excitability reflected people’s speed difference of emotion generation; (4) Changing speed of emotional excitability reflected people’s changing speed difference between different emotions or different emotion degrees; (5) Controllability of emotional excitability reflected people’s controllability difference of emotions; (6) Explicitness of emotional excitability reflected people’s explicitness difference of emotions. The questionnaire was administered to 5831 students from Shanghai, including primary school students (fourth-grade and fifth-grade), junior school students, senior high school students and undergraduates (vocational college students and university students). The results showed: (1) The questionnaire meets the criteria of an effective measurement tool and serves as an original investigative tool for affective diathesis of college students. (2) In every schooling stage (primary school, junior school, senior
FRS-XRSA与SAXS研究硬弹性聚丙烯的结晶度、取向与超结构Ⅲ应变与回复

Abstract: 应用全倒易空间X射线散射理论分析(FRSXRSA)与SAXS研究了HEPP在应变(ε)与回复(R)过程中结晶、取向与超结构的变化.结果指出,ε可以诱发结晶,但当ε≥30%后,结晶度(XWC)趋于不变ε可以导致晶粒破碎;ε与R对取向分布与平均取向基本上无影响,这符合片晶平行分离模型,而非叶簧弯曲模型;发现,在ε≤30%时,层状片晶的分离为主要过程,而当ε>30%后,则分离的片晶会发生断层滑移;ε可以诱发微孔,类似地当ε>20%,微孔尺寸亦趋不变.从凝聚态结构阐明了HEPP在εR过程中不同阶段的结构变化

Abstract: Affective diathesis refers to the individual’s emotional psychological quality. The college students’ affective diathesis questionnaire has six sub-questionnaires including thirty-three different kinds of affects. A large-scale investigation on the affective diathesis was administered to 11982 college students involving 100 colleges and universities of 14 major cities. With the purpose of more convenient, in-depth understanding of the affective diathesis of college students, this paper uses the decision tree algorithm to predict the affective diathesis of college students and their subordinate affections based on the research above. Decision tree is a supervised classification algorithm for data classification in the field of data mining. Through the approach of creating a classification function or classification model by learning the sample set, the function or classification model can map data records to one category, which can be used for the prediction of data classification. The decision tree consists of decision nodes (also called root nodes), branches (approach decision), and leaves (finally result), making themselves into a tree structure, which represents the final classification result (each approach represent one kind of result). In present study, each node in the tree represents a property of the analysis object such as moral affectivity, self-improvement affectivity and so on. Moreover, each branch represents a possible value for this attribute. Therefore, the approach from the root node to the leaf node corresponds to a reasonable rule. These rules are usually described in the form of If-then. The combination of the attribute and the value of attribute formed along the path from the root node of the decision tree constitutes the part represents “if”, then the category marked by the leaf node forms the “then” part of the rule, which draw the conclusion of the rule. The specific affectivity and various affectivities based on the score it has got is divided into five grades, which from bad to good is "worse", "poor", "general", "good", "excellent". Actually, the data set is divided into a sample set and a test set, and the software called Weka can generate a decision tree model by using the sample set as a data source to analyze the relationship between attributes. At the same time Weka uses the test set to
