本研究采用问卷法对2929名在校大学生进行施测,考察了睡眠卫生习惯与大学生失眠的关系以及睡眠拖延在其中的中介作用和睡眠信念的调节作用。结果表明:1) 大学生睡眠卫生习惯与失眠存在显著关联,即大学生睡眠卫生习惯越差,失眠症状越明显;2) 睡眠拖延在睡眠卫生习惯与失眠之间起部分中介作用;3) 中介模型的三条路径均受到睡眠信念的调节。这些发现一方面揭示了睡眠卫生习惯与大学生失眠的关系及作用机制,另一方面也为预防和干预大学生失眠带来一些重要启示。This paper investigated the relationship between sleep hygiene practice and insomnia symptoms in college students and the mediating role of bedtime procrastination as well as the moderating role of sleep beliefs. A sample of 2929 college students completed questionnaires measuring sleep hygiene practice, bedtime procrastination, sleep beliefs, and insomnia. The results showed that: 1) sleep hygiene practice was significantly associated with college students’ insomnia, which indicated that the poorer sleep hygiene practice, the more severe insomnia symptoms in college students;2) bedtime procrastination partially mediated the relationship between sleep hygiene practice and insomnia;3) the mediating effect of bedtime procrastination and the directing effect of sleep hygiene practice were significantly moderated by sleep beliefs. These findings revealed the inner relationship between sleep hygiene practice and insomnia as well as its underlying mechanisms, and also brought some important inspirations for the prevention and intervention of college students’ insomnia in real life.
扫描电子显微镜(Scanning Electron Microscope,SEM)是获得物质表面微观形貌的常用工具之一。获取宣纸的表面形貌和宣纸的纤维结构是古籍保护与修复造纸工序的一项重要依据。但目前,大多数研究仅仅停留在光学显微镜对于纸张纤维的单个分析,基于纳米尺度的相关研究很少。因此,文章把四种现代品牌的棉连纸作为实验研究对象,利用扫描电子显微镜获得其表面的微观形貌交织和内部纤维尺寸信息。希望能为古籍保护与修复的纸张选择提供新的思路和手段。
