激光靶测速相对误差影响因素研究

激光靶测速是速度测量的一种重要的实验方法,其测试效率高、精度高、抗干扰能力强、测速范围大、受环境因素影响小,很有工程应用前景。针对激光靶速度的实际工程应用背景,深入、系统地研究了在匀加速阶段和匀速阶段测速时影响测速相对误差的因素,得出了在这两个典型阶段测速时,激光靶的安装位置及其精度与测速相对误差的重要关系。同时,分析得到了在给定测速相对误差前提下,激光靶的最佳安装间距。上述结果对激光靶测速的相关工程应用和相关实验的设计与开发具有重要的指导意义。

Assessing South China (Guangzhou) High School Students’ Views on Nature of Science: A Validation Study

Research on students’ views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students’ VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial aspects of NOS indicated by the literature and/or the dominating ideology in China (i.e., Marxism). A sample (N = 604) was randomly divided into two groups used for exploratory analyses and confirmatory analyses. The results indicated that the instrument expressed satisfactory reliability and validity and the seven NOS dimensions could be explained by a higher-order dimension. That is, the data of this study supported the multi-dimensional framework that treats VNOS as comprising several more-or-less correlated dimensions. Two distinct dimensions, namely “Accumulative-Empirical Source” and “Pragmatic Justification” which have not been explicitly specified in the past literature, were found. In addition, the Chinese high school students generally held a constructivist/relativist-oriented view of all seven dimensions. Differences in gender and grade level were hardly observed in any dimension of the instrument. The findings are further discussed through a socio-cultural lens to enrich the current understanding of VNOS.     

Periodontal status and associated risk factors among childbearing age women in Cixi City of China

Objective:To investigate the periodontal status and associated risk factors among women of childbearing age to increase the awareness of oral health.Methods:The study was conducted on childbearing age women in Cixi,a city in Zhejiang Province in the southeast of China.A total of 754 women participated in periodontal examination while receiving prenatal care.Data of the women were collected from the Cixi Family Planning Commission and during an interview.Clinical periodontal indices,such as bleeding on probing(BOP),probing depth(PD),and clinical attachment level(CAL) were measured during the examination.Statistical analysis on subject-based data was performed.Results:The prevalence of periodontal disease among childbearing age women in Cixi was high(84.7%).A significant association was found between the disease and educational level,pregnancy,taking oral contraceptives,stress,alcohol consumption,overweight,dental visit,and teeth brushing(P<0.05).Women who suffered periodontal disease showed deep PD,obvious BOP,and clinical attachment loss.Among this population,pregnancy was closely associated with higher BOP percentage;teeth brushing no more than once per day or brushing for less than 1 min(P<0.001) after adjusting for age and stress.Conclusions:The periodontal status of childbearing age women in Cixi needs to be improved urgently.Attention towards the periodontal health should be warranted,especially for those in special statuses and with poor awareness.     

灵韵的消逝与技术复制时代感知方式的变迁——本雅明“灵韵”概念重新解读

本文通过对本雅明作品的文本分析,认为"灵韵"是一种本雅明式的独特感知方式,建立在经验交流的基础上,其运作的心理机制是普鲁斯特式的非意愿记忆和弗洛伊德的自由联想法。此概念是本雅明传媒技术与文化批判的起点,由此形成的一套传媒文化理论在今天仍具有认识论的指导意义。     

“感觉”的运用实现了科学歌唱发声状态培养的简化

一切的声乐技能都是靠自己的意识来控制发声器官的,按照意识预定要求进行动作结果的。发声的各个器官的互相搭配其实也是人的一种本能的意识反应,建立科学发声状态是通过自身感觉的调控,使复杂的肌肉运动准确化、歌唱运用共鸣和呼吸合理化、技巧的掌握简单化,最后实现演唱的自动化。     

评价视角下大学生英语习作的介入策略研究

笔者从评价理论之介入视角对英语专业四级学生作文的介入策略进行研究.通过对本学院英语专业2年级学生20份习作和2份专四作文进行介入资源的分析和统计,发现学生在通过作文与阅卷教师进行人际交流时,使用最多的介入资源是自言.学生趋向于直接介入文章事态,直言其态度.进一步进行细化考究,自言中的否认资源占了明显优势.此外,一致和引发资源也被较多的使用.这些策略的使用一方面帮助作文作者清晰地表达个人观点,另一方面又能协调作者与阅卷教师的关系,从而获取高分.在2篇分数和等级完全不一样的四级样文中考究其介入资源的声音来源,发现高分样文的主语使用比较紧凑,人称选择比较固定,叙事角度较为稳定;而低分样文主语变换较多,人称变化也漂浮不定,从而导致叙事角度不停变换,连贯表达难度增加.     

High school students’ scientific epistemological beliefs,motivation in learning science,and their relationships: A comparative study within the Chinese culture

This study explored the differences in high school students’ scientific epistemological beliefs (SEBs), motivation in learning science (MLS), and the different relationships between them in Taiwan and China. 310 Taiwanese and 302 Chinese high school students’ SEBs and MLS were assessed quantitatively. Taiwanese students generally were more prone to believe that scientific reality is invented, the development of scientific knowledge is culture-dependent, and scientific knowledge is always changing and its status is tentative than the Chinese students were. Yet, the Taiwanese students perceived higher test anxiety in science than the Chinese students did. Moreover, Chinese students who have a stronger belief that science knowledge is changing and tentative are more likely to perceive themselves as having higher test anxiety in science. The results suggest that the role of culture might have an impact on students’ SEBs and their MLS.
