    企业对企业(BTOB)营销不同于企业对普通消费者(BTOC)营销的模式,企业客户在营销中的购买行为拥有着自己的流程和特点。因此在选用的营销分析模型时不能简单照搬套用针对普通消费者的理论模型。BTOB营销虽然已经开始受到我国学者的重视,但对工业品客户购买行为的研究,在我国还处于刚刚起步阶段。本文根据ABB所属输配电设备行业营销的特点,对影响我国输配电设备市场的发展情况进行介绍,选择使用“韦—温模型”对影响ABB客户采购的外部因素和购买行为因素进行分析。在此基础上,本文综合利用层次分析法、德尔菲法和线性加权法等评价方法构建了适合该行业的采购核心小组角色的客户购买行为问卷,对ABB企业案例进行了分析...Business to Business (B TO B) marketing differs from business-to-consumers (B TO C) mode of marketing, corporate clients in marketing their buying behavior has a process and characteristics. Therefore, the choice of marketing analysis model can’t simply follow the applied theoretical model for the average consumer. B TO B marketing although Chinese scholars have begun to attract attention, b...学位:工商管理硕士院系专业:管理学院工商管理教育中心(MBA中心)_工商管理硕士(MBA)学号:X20041531

    针对整体硬质合金刀具曲面结构复杂、参数化直接建模难以实现的问题,对整体硬质合金立铣刀的三维参数化直接建模进行了研究。分析了整体硬质合金立铣刀中包含的复杂曲线与曲面,将立铣刀的三维模型划分为5个重要特征,在三维建模过程中对每个特征根据刀具的设计规则进行了详细的数学建模,提取出了影响特征生成的关键几何设计参数,为每个特征建立了通用数学模型,通过ug/OPEn二次开发工具完成了立铣刀参数化界面设计,并在ug环境下建立了整体硬质合金刀具参数化设计系统。研究结果表明,整体硬质合金刀具参数化设计系统实现了复杂曲面刀具的参数化直接建模,节约了曲面方程的计算时间,有效提高了刀具设计与建模效率。Aiming at realizing the direct modelingon solid carbide cutting tools with complex surface structure,the three-dimensional modeling of solid carbide end mills was researched.Complex curves and surfaces contained in the solid carbide end mills were analyzed, models of solid carbide end mills were divided into five features,each feature had detailed mathematical equation based on the tool designing rules during the modeling,the key geometric parameters influencing the feature generation were extracted,and each feature correspond to a general mathematical model.At last,the parametric interface design and parametric system of solid carbide cutting tools were built up by UG/Open secondary development tools.The results indicate that,the system completes the parametric direct modeling on solid carbide cutting tools with complex surfaces,saves the computing time of surface equation,improves the design and model efficiency of tools.厦门市重大科技计划资助项目(3502Z20131007

    为了探讨戊型肝炎病毒多聚蛋白ORF1的多个功能域在宿主细胞中的表达和定位情况,我们首先将psk-HEV重组载体上的ORF1各功能域的编码序列克隆到绿色荧光蛋白载体pcDNA3.1-GFP上,构建成融合表达的重组质粒,并测序和酶切鉴定其构建成功。再通过Western-Blot验证各融合蛋白在细胞中正确表达,并用激光扫描共聚焦显微镜观察融合蛋白在细胞内的分布和定位。在Huh7细胞中,RdRp蛋白主要分布于细胞核内,HEL蛋白以囊泡状分布于细胞核周,MET蛋白以颗粒状存在于细胞核和细胞质中,PLP蛋白呈极性分布于细胞核周,X蛋白在细胞核和细胞质中均存在。各融合蛋白在细胞中的不同定位印证了对这些蛋白质的功能预测和体外研究结果,这为进一步研究HEV不同蛋白功能提供了支持

    目的:探讨孤独症谱系障碍(ASD)儿童心理推理能力(ToM)与局部脑功能连接的关系。方法:选取符合DSM-5诊断标准的6~18岁ASD儿童39例和年龄、性别及智商相匹配的正常儿童43例,进行ToM任务测查和静息态磁共振成像扫描,比较两组ToM通过率/得分和全脑局部一致性(ReHo)缺陷的脑机制值,并采用偏相关方法分析两组间存在差异的ToM通过率/得分和ReHo值之间的关系。结果:ASD组显性错误信念、一级错误信念通过率和表情识别任务得分低于正常对照组(均P&lt;0.05);右额上回局部ReHo值高于正常对照组,右距状沟、左内侧额叶皮层区域ReHo值低于正常对照组(GRF校正,体素P&lt;0.001,团块P&lt;0.05)。结论:ASD患者存在ToM缺陷和局部一致性异常,其中显性错误信念与左内侧额叶皮层局部功能连接相关。</p
