Methods: A total of 629 subjects were administered the Index of Well-being, State-Trait Anxiety Inventory, and Symptom Checklist-90. Results: Significant gender difference was found on the index of well-being. There was also significant correlation between index of well-being and negative emotionality. Index of Well-being was negatively correlated with factor scores of emotionality including state anxiety, trait anxiety, and SCl-90-depression. Conclusion:The "Index of Well-being”is psychometrically sound for application to Chinese college students.展开更多
用PIT(powder in tube)法在不同条件下制备MgB2样品,通过X射线衍射、扫描电子显微镜(SEM)对不同参数下制备样品的成分和微观结构进行了表征;利用Campbell法检测样品的bac-λ′关系,求得样品的超导临界转变电流密度Jc;由样品的Jc结合形...用PIT(powder in tube)法在不同条件下制备MgB2样品,通过X射线衍射、扫描电子显微镜(SEM)对不同参数下制备样品的成分和微观结构进行了表征;利用Campbell法检测样品的bac-λ′关系,求得样品的超导临界转变电流密度Jc;由样品的Jc结合形貌与相成分对比分析,结果表明:长时间烧结,晶粒较大,利于导电,但缺乏钉扎作用,在外磁场下超导电流减小。长时间烧结,晶界间氧化层增厚,超导电流密度减小。展开更多
PIT(powder in tube)法制备了MgB2超导材料;用Campbell法测量了样品的外加交流磁场bac与磁通渗透深度λ′的关系,并计算得到样品在外磁场中的临界电流密度;讨论了bac-λ′,曲线误差形成的原因和选取曲线平稳部分为计算有效段原则;Campb...PIT(powder in tube)法制备了MgB2超导材料;用Campbell法测量了样品的外加交流磁场bac与磁通渗透深度λ′的关系,并计算得到样品在外磁场中的临界电流密度;讨论了bac-λ′,曲线误差形成的原因和选取曲线平稳部分为计算有效段原则;Campbell法测量考虑了样品的整体结构影响电流的特性,得到的结果更切合超导材料的实际临界电流密度。展开更多

In this paper, four elements of tourist route design were identified to form the list of tourist route design principle. Based on the analysis of Campbell model, four-point inspiration for tourist route design was summarized, a Campbell model-based schematic of the tourist route design of Rizhao was formed grounded on the analysis of tourism resources and service facilities in Rizhao, so as to explore the optimal way of the tourist route design.展开更多
