摘要：近几年,快时尚的出现与服装存量与增量的逐年上升引发了极大的浪费。仅我国每年产生的废弃纺织品总量约2 600万吨,在废旧纺织品回收利用上还不到万分之三,对环境造成了严重的影响。本课题通过研究国内外废弃服装再利用的现状与在艺术领域的价值体现,使废旧服装再生设计成为一种本能设计。

摘要：从微观动力学角度对企业的环境行为进行分析,从而识别影响企业改善环境行为的关键因素,对寻求促进企业改善环境行为的最优方式,并为政府制定有效的环境政策有着积极和迫切的意义。以世界自然遗产武陵源所在地张家界市的酒店企业为研究标耙,基于对不同类型酒店环境行为存在差异性的假设,采用33个环境行为测量指标,从酒店建筑和景观设计、能源管理、水资源管理、废弃物减量、环保意识沟通、环保管理知识等6个方面进行测度。结果表明:张家界市酒店企业6个度量项目环境行为指标的组均值分别为1.91,2.04,1.77,1.95,1.62,1.45,在环保管理知识、环保意识沟通、水资源管理3个方面的表现较为欠缺;高星级酒店没有与低星级酒店、社会旅馆在大部分环境行为指标的分值上拉开差距;最后就改善酒店企业环境行为提出相关建议,其中主要包括增强酒店企业的环保责任意识,力促酒店企业运营模式转型以及加强对遗产旅游地酒店企业的调控与引导等。

摘要：针对我国纤维材料艺术品的优缺点,对彩织的摩擦、皂洗、汗渍色牢度和唾液色牢度进行了测试分析。结果表明目前的彩织产品在基本指标上达到了要求;且如能成功解决产品的柔软度、厚度及贴肤性触感等问题,彩织产品将具有更大的应用空间。

摘要：介绍了家用纺织品的起源和概念、国内家用纺织品销售的现状和问题,分析了家用纺织品卖场展示对其销售的影响与功效,旨在推进优秀的家纺卖场展示设计,以提高销售利润,对家纺业产生积极的作用。

摘要：针对基于模糊C均值聚类(FCM)的图像分割算法仅利用像素的灰度信息、噪声抑制不理想、算法鲁棒性不高的问题,提出了一种基于像素邻域信息约束的FCM图像分割算法。该算法在模糊目标函数中引入邻域信息约束,通过约束系数自适应调节控制邻域信息约束强度,自优化迭代更新聚类中心和聚类隶属度矩阵,使模糊目标函数收敛到最小,并利用像素最优聚类隶属度去模糊化操作实现图像分割。实验结果表明,该算法在获得较高的图像分割精度的同时,具有较强的噪声抑制能力。

摘要：铁路客运站的安检流程是保障旅客出行安全、提升铁路服务质量的重要举措。近年来,传统客运站的安检方式与高速铁路旅客方便快捷的出行需求间矛盾日益突出。以北京南站为例,结合历史客流数据,通过调查安检通道的具体参数、旅客在通过安检通道过程中的行为参数,利用Anylogic仿真软件建立铁路客运站旅客安检通道模型,对旅客的安检流程进行分析。根据仿真结果,得到旅客平均排队长度、旅客平均排队时长、旅客通过安检通道平均时间等参数,分析安检流程设置的瓶颈,得出采取增加检查点或替换新型X光机的优化方案后,旅客安检效率得到显著提升,旅客在各个队列的等待时间以及旅客在安检通道中花费的时间均优于以往的安检流程,从而对提升铁路客运服务质量、保障便捷高效的运输服务提供支撑与借鉴。

摘要：采用DMAc/liCl/Chitin/HA溶胶-凝胶体系获得了直径在100-150 m、连续长度的HA陶瓷纤维。研究进一步设计了一种由HA粉体和HA短纤维制成多孔HA陶瓷的方法,通过改变添加的制孔剂和纤维的数量,可制备气孔率在60%-80%的三维支架。扫描电镜观测支架结构,X射线衍射图谱分析样品晶相,万能材料测试机测试样品抗压强度,结果表明混入同质纤维,样品仍保持较好的贯通性,在相同开气孔率下样品抗压强度提高幅度95%-110%。

摘要：Several novel C-pseudonucleosides containing thiazolidin-4-one and phenyl connected by acetamide bond were rationally designed and easily synthesized at room temperature by using the unprotected sugar aldehyde as the starting material. The effects of the compounds on Con A-induced T cell proliferation were evaluated at five concentrations of 5, 10, 25, 50, and 100 mmol/L Interestingly,compounds 7a and 8a（n = 2, R = H） exhibited immunostimulating activities, while compounds 5a, 6a（n = 1, R = H） and 7b, 8b（n = 2, R = CH3） showed immunosuppressive activities. Another two compounds 5 b and 6b（n = 1, R = CH3） had no immunomodulating activities. These initial biological results suggested that subtle structural changes to the phenyl and acetamide bond of C-pseudonucleosides could have a significant effect on T cell proliferation bias, although it was difficult to formulate a rigorous structureactivity relationship based on the observed activities.
