Research on Supply Chain Coordination in the Perspective of Cost Management

供应链是典型的需要协调的系统。基于成本管理的供应链协调机制能使供应链的总成本最低，总收益最大化，实现供应链节点企业的共赢。本文从成本管理的角度，分别研究核心企业与上下游之间的供应链协调。在制造商与供应商的协调过程中，根据依赖性的强弱、供应商参与程度高低和双边承诺的多少，核心企业可以将供应商分为战略伙伴供应商、主要供应商、承包商和普通供应商，不同的供应链节点企业关系类型影响成本管理协调方法的选择，对供应链成本缩减的贡献由高到低。核心企业对非战略伙伴关系的供应商采用成本共担的协调机制，激励供应商参与产品设计。运用博弈论的方法，得出存在Pareto改进使供应链合作的收益大于非合作下收益的结论，成本共...Supply chain is a typical system which is needed to be coordinated. By using the supply chain coordination mechanisms based on cost management, the overall costs will be minimized and the total profits will be maximized and firms in the supply chain will get a multi-win goal. So, this thesis analyzes the supply chain coordination between the core enterprise and its downstream and upstream respecti...学位：管理学硕士院系专业：管理学院管理科学系_技术经济及管理学号：2005130127

单晶6H-SiC经氦离子辐照及退火后的微观组织研究

在400℃下对单晶6H-SiC进行了400keV氦离子辐照,辐照剂量为1×1016He+/cm2,随后在1200和1500℃退火30min。采用透射电子显微镜和扫描电子显微镜对辐照态和退火态SiC进行微观结构观察与分析。结果表明,单晶6H-SiC在400℃经氦离子辐照后,仅观察到由辐照引起的位移损伤带,而未观察到明显尺寸的氦气泡。但经1200℃退火30min后,在辐照损伤区域形成了呈血小板状的气泡簇,其主要分布在（0001）晶面上,少量形成在（1120）晶面。辐照未在6H-SiC表面上形成明显尺寸的缺陷,而经1200℃退火30min后,SiC表面出现大尺寸的起泡和凹坑,进一步提高退火温度至1500℃时,表面起泡和形成凹坑更严重,并产生了大量裂纹。本研究同时对微观结构演化的机理进行了分析与讨论。中国工程物理研究院NPL,CAEP项目资助(2015AB001

Determination of Andrographolide and Dehydroandrographolide in Andrographis paniculata Nees Materials and Related Patent Medicines by Reversed-Phase High Performance Liquid Chromatography

发展了穿心莲药材及其中成药中两种主要成分穿心莲内酯和脱水穿心莲内酯的反相高效液相色谱测定方法。采用甲醇振荡提取法进行样品前处理 ,在以乙腈 水为流动相作梯度洗脱、ODS柱、检测波长为 2 2 5nm的条件下 ,穿心莲内酯和脱水穿心莲内酯在 1 5min内可达到基线分离。两种内酯在 1 0mg/L～ 1 0 0mg/L时其浓度与峰面积成良好的线性关系 ,加标回收率为 96 %～ 1 0 4 %。该法适用于穿心莲药材及其制剂的质量分析检验A simple and accurate method for the determination of andrographolide and dehydroandrographolide in andrographis paniculata Nees materials and patent medicines with high performance liquid chromatography (HPLC) has been developed. The two components were extracted from powdered samples by shaking with methanol. The resultant extracts were separated within 15 min on a BECKMAN C 18 column (4 6 mm i d ×250 mm, 5 μm) and with a gradient elution of acetonitrile water at a flow rate of 0 5 mL/min . The detection wavelength was 225 nm and the injection volume was 20 μL. In gradient elution program the volume fraction of acetonitrile in mobile phase was as follows: 0 min-1 min, 40%; 1 min-5 min, 40%-50%; 5 min-15 min, 50%-70%. Both andrographolide and dehydroandrographolide have good linearity in the range of 10 mg/L to 100 mg/L with the correlation coefficients of 0 997?6 and 0 998?6 respectively. This method has been successfully applied for the analysis of andrographis paniculata Nees materials and related patent medicines.科技部中药现代化重中之重项目( 99 92 9 0 213);; 福建省科技部中药质量控制重点项目 (2 0 0 0F0 0 1)

The Magnetic Field in Quiescent Star-forming Filament G16.96+0.27

We present 850 μm thermal dust polarization observations with a resolution of 14.″4 (∼0.13 pc) toward an infrared dark cloud G16.96+0.27 using James Clerk Maxwell Telescope/POL-2. The average magnetic field orientation, which roughly agrees with the larger-scale magnetic field orientation traced by the Planck 353 GHz data, is approximately perpendicular to the filament structure. The estimated plane-of-sky magnetic field strength is ∼96 μG and ∼60 μG using two variants of the Davis–Chandrasekhar–Fermi methods. We calculate the virial and magnetic critical parameters to evaluate the relative importance of gravity, the magnetic field, and turbulence. The magnetic field and turbulence are both weaker than gravity, but magnetic fields and turbulence together are equal to gravity, suggesting that G16.96+0.27 is in a quasi-equilibrium state. The alignment between the magnetic field and cloud is found to have a trend moving away from perpendicularity in the dense regions, which may serve as a tracer of potential fragmentation in such quiescent filaments
