产业组织视角下零售商通道费行为

将一次性支付的通道费与产业链产量相联系,利用斯坦尔伯格博弈逻辑考察零售商通道费行为与上下游厂商谈判势力的关系以及该行为对于产业链效率的影响.研究结果表明,零售商通道费行为可以改善产业链效率,具体表现为零售商利润与产业链总利润随零售商买方势力增强而增加,但供应商收益会受到损害.特别地,零售商可以选择通道费策略以使产业链利...     

Study of Un-added Allowance of Draping-PIanar Designing Garment Prototype for Young Ladies

As for the theory and method in garment structural design according to human figures, a principle for garment design, i. e. body-fitting without added allowance, and a combination of draping and planar design (DPD hereunder) for young ladies has been put forward, and, also, a DPD garment prototype for them has been established. And the applied formulae for extensively-practicing operation have been set up, which proves to be, with actual samples, a systematic and practical garment structural designing theory and approach.     

博士后研究人员绩效激励机制探讨

PHM项目研制的进度风险与技术成熟度要求

统计分析各国目前已完成的预测与健康管理(Prognostic and health management，PHM)项目相关资料,得到技术成熟度等级与相对进度拖延的原始数据。通过转化为线性回归的方法,建立技术成熟度等级与平均相对进度拖延和最大相对进度拖延的回归函数,并检验回归函数线性假设的显著性。假设相对进度拖延服从正态分布,确定进度风险与技术成熟度的概率关系。绘制进度风险、进度余量与技术成熟度等级的关系图。结果表明:PHM的技术成熟度达到7级时,项目研制的进度风险控制在20％以内,处于可以接受的范围。

Study on the Relation between Garment Style and Ease Distribution

IntroductionGarment pattern design is a 3 D to 2 D surfacemapping process. Traditionally, thegarmentpattern designcan be classified as “Drafting Method” and “DrapingMethod”.“Drafting”is a direct drawing of the garmentpattern using known body measurements from themannequin. Since this method does not requiremanipulation in the 3 D space, it is called“flat patterntechnique”. All flatpattern design masters approximate thegarment pattern using …

Analytical relations for luminescence intensities accounting for reabsorption

Mathematical relations defining distortions from true values of photoluminescence intensities that arise during measurements due to absorption at the luminescence frequencies are derived for various experimental designs. The adequacy of the derived relations is confirmed by special experiments. The relations allow one to define correctly the contours, widths, and maximum frequencies of luminescence bands of absorbing media and to deduce absorption coefficients of substances from luminescence measurements.
