乙二胺四乙酸桥联锰配合物的结构和磁行为

A trinuclear Mn(Ⅱ)coordination complex Mn_3(HEDTA)_2·10H_2O(EDTA=ethylene diamine tetraacetic acid)1 has been synthesized and characterized by X-ray crystal structure determination.In addition,IR spectrum,thermogravimetric analysis,electron paramagnetic resonance(EPR)spectra and magnetic susceptibility of this complex are discussed.X-ray determination indicates that six-and seven-coordinate modes between Mn(Ⅱ)and H_4EDTA exist alternately in 1.Furthermore, detailed discussion of magnetic ordering in the temperature range of 2～300 K reveals the antiferromagnetic interactions in the complex.

语篇分析与大学俄语写作教学

写作能力的培养是大学俄语教学中一个重要的环节在写作教学中，除了教授学生利用准备的词句来表达自己的思想，突出主题外，还要使学生采用一定的写作手法，按一定的逻辑顺序将符合文章主题的各种信息材料组织成主题突出，语义连贯，结构严谨，文章流畅的篇章结构。本文从培养学生的句子意识，段落意识和篇章意识三个方面来探讨提高写作能力问题。     

Aggregating concept map data to investigate the knowledge of beginning CS students

Concept maps have a long history in educational settings as a tool for teaching, learning, and assessing. As an assessment tool, they are predominantly used to extract the structural configuration of learners’ knowledge. This article presents an investigation of the knowledge structures of a large group of beginning CS students. The investigation is based on a method that collects, aggregates, and automatically analyzes the concept maps of a group of learners as a whole, to identify common structural configurations and differences in the learners’ knowledge. It shows that those students who have attended CS education in their secondary school life have, on average, configured their knowledge about typical core CS/OOP concepts differently. Also, artifacts of their particular CS curriculum are visible in their externalized knowledge. The data structures and analysis methods necessary for working with concept landscapes have been implemented as a GNU R package that is freely available.

紫藤和凌霄花的输水结构与水流速度的初步研究

用热脉冲技术，测定了2种藤本植物紫藤(Wistaria Sinensis)和凌霄花(Campsis Chinensis)茎干的液流速度。对两种植物的输水结构进行了解剖学研究，结果表明，两种植物一天中的液流速度变化小，维持在较高速度值上，径向液流速最大值的位点均位于靠近形成层的区域。二者输水结构也表现出了相似的特征，两树种的液流速度与其解剖结构有密切的关系。
