A cobalt（II） coordination polymer, [Co（dimto）2（H2O）2]·4H2O[1, dimto=4,6-di（1-imidazolyl）-1,3,5- triazine-2-one], has been prepared under solvothermal condition. Single-crystal structural analysis reveals that compound 1 crystallizes in the orthorhombic space group Ibca（No.73） with a=1.80696（12） nm, b=1.93224（11） nm, c=1.36798（10） nm, V=4.7763（5） nm3 and R1=0.0438. Compound 1 is a 3D supramolecular architecture composed of 1D wave-like chains with hydrogen bonds and π-π interactions. Compound 1 was further characterized by powder X-ray diffraction（PXRD）, infrared（IR） spectroscopy, thermogravimertic analysis（TG） and elemental analysis. Additionally, the magnetic property of compound 1 was also investigated.

晚唱中的变调:庚辛禁毁小说运动考论

1900-1901年,江浙地区发生了一场大规模禁毁小说运动,可简称为庚辛禁毁运动。该运动是由杭州协德善堂认真议定应禁单目,于1900年初,由杭州官宦子弟樊达璋、许之荣等士绅出面禀请浙江学政文治并移咨江苏布政使陆元鼎和按察使朱之榛通饬... 详细信息

1900-1901年,江浙地区发生了一场大规模禁毁小说运动,可简称为庚辛禁毁运动。该运动是由杭州协德善堂认真议定应禁单目,于1900年初,由杭州官宦子弟樊达璋、许之荣等士绅出面禀请浙江学政文治并移咨江苏布政使陆元鼎和按察使朱之榛通饬执行。由于协德善堂在江浙官场较有影响力以及陆元鼎、朱之榛与协德善堂关系密切,禁毁小说运动迅速在江浙两省展开;1900年12月,同善社继起,接过了协德善堂的禁毁接力棒,再次把禁毁运动推向又一个高潮;庚辛禁毁运动是清代最后一次大规模禁毁小说活动。从禁毁单目上看,反对小说诲淫和迷信是本次禁毁运动的两大动因,诲淫和迷信也是清末小说改良运动针对的重要对象。可见,在义和团运动兴起之际暨小说界革命开启的前夜,小说诲淫和迷信两大问题被不少官员和士绅同时关注,这种关注有助于我们认识清末禁毁小说活动与小说改良运动之间的互动与转换。

目的对国内外博物馆展示交互设计的相关文献进行分析与总结,探讨该领域的研究热点、演进历程、发展趋势及国内外发展差异,并找出差异形成的原因,为今后博物馆展示交互设计的发展提供思路。方法以1995一2023年CNKI中国知网、Webof Science两大文献数据库作为数据来源,以1401篇博物馆展示交互设计相关文献为分析对象,经CiteSpace软件的运行,就国内外学界的已有研究生成相应的关键词共现图谱,并生成关键词聚类合成知识谱图,对该领域文献的发文统计、文献分布情况、作者、机构及关键词等内容进行梳理、知识图谱的生成及可视化分析。结果研究结果表明,国内外针对博物馆展示交互设计的研究都围绕观众展开,同时也都强调利用数字技术进行多感官体验的打造。但国外研究更注重以用户体验为中心的设计理念,研究重点聚焦以参与需求为目的社交空间等维度。国内研究则更多关注以数字展示为手段的展示内容上的感官呈现,更注重博物馆文化的传播。结论由于国内外博物馆展示交互设计中展陈设计理念、空间叙事逻辑、传播媒介偏向的不同,出现了基于不同研究视角的发展差异。伴随着社会职能的不断拓展与科学技术的不断进步,未来博物馆将在技术应用、展示功能、职能变革和交互体验等方面产生更多突破。

为探究吉县近30 a植被动态演变规律及其影响因素,本研究基于Landsat影像,结合气象、土地利用、夜间灯光等数据,采用趋势分析、偏相关分析、随机森林、残差分析等方法探究吉县植被覆盖度时空变化特征及气候和人为因素对植被变化的影响。结果显示:(1)1990—2020年研究区植被覆盖度(FVC)整体呈显著上升趋势,FVC年均增长速率约为0.49%,植被质量明显改善。(2)吉县FVC具有明显的“低值-高值”交错分布的空间特征。1990—2020年FVC显著增加区占51%,FVC显著减少区占7%。(3)气候因素对部分FVC高值区和建筑区植被生长起抑制作用,对其余地区植被覆盖起促进作用。将人类活动作为全域影响因素考虑时气候和人类活动对植被动态的贡献率分别为53.43%、46.57%,将其作为局域变量时相对贡献率减少至13.07%。人类活动在特定地区如吉县中部和东部是植被退化的重要影响因素,西侧和南部的植被恢复也与之相关。研究结果可为区域生态修复工作进一步开展提供科学依据。
