摘要：快递包装物的智能回收是解决当前物流行业面临的回收成本高、配合意愿低、盈利难等问题的大势所趋。通过文献研究法和问卷调查法基于SERVQUAL模型梳理了影响用户使用快递包装物智能回收箱意愿的影响因素。运用SPSS26.0将用户参与意愿影响因素划分为“服务运作”、“服务体验”、“服务便捷性”三个重要维度并分析其影响,在此基础上提出了快递包装物智能回收箱设计的相关建议。

摘要：为科学客观地确定木结构建筑的可靠性,构建一种基于三角模糊数层次分析法(TFN-AHP)的模糊综合评估方法。依据环境因素对木结构建筑的构成要素造成的影响选取木材开裂、受潮、虫蛀、强度、腐朽、构件变形、连接件松动及锈蚀共8个参数构成评估指标体系;运用TFN-AHP为各项指标分级赋予权重,并依据GB 50005-2017《木结构设计标准》等划分可靠性评估等级;将指标分类处理以确定各指标隶属向量,依据模糊综合评估原理得出木结构建筑可靠性等级;并结合牡丹江市某木结构建筑进行工程实例分析,为木结构建筑的维修加固工作提供科学指导。

摘要：Seeking catalysts with high electrocatalytic activity for ambient-condition N2 reduction reaction (NRR) remains an ongoing challenge due to the chemical inertness of ***,defect-rich WS2 nanosheets (WS2-x) were designed as an efficient electrocatalyst for NRR,which were prepared via vulcanizing the oxygen-vacancy-rich tungsten oxide in a vacuum *** sulfur defects were conducive to the adsorption and activation of *** neutral electrolyte of 0.1 mol L^(-1)Na2SO_(4) at-0.60 V *** hydrogen electrode,such WS2-xoffered a high Faradaic efficiency of 12.1%with a NH3generation rate of 16.38μg h-1mg-1cat..
