供应链中多供应商与单零售商的利益分配问题研究

本文利用合作博弈的方法，研究了“多供应商-单零售商”组成的供应链中成员的合作及利益分配问题。由于供应链中所有成员之间相互竞争时产生的利益是无效率的，供应链成员只有合作形成大联盟才能保证整体和成员局部利益更优。本文分析了大联盟的可行性，给出了相应的稳定利益分配方案。结果表明，零售商加入由供应商组成的“协作”联盟，是实现供应链各方利益最优化的有效途径。

双圈连通图的L(2,1)-labelling

给定图G,G的一个L(2,1)-labelling是指一个映射f:V(G)→{0,1,2,…},满足:当dG(u,v)=1时,f(u)-f(v)≥2;当dG(u,v)=2时,f(u)-f(v)≥1.如果G的一个L(2,1)-labelling的像集合中没有元素超过k,则称之为一个k-L(2,1)-labelling.G的L(2,1)-labelling数记作l(G),是指使得G存在k-L(2,1)-labelling的最小整数k.如果G的一个L(2,1)-labelling中的像元素是连续的,则称之为一个no-holeL(2,1)-labelling.本文证明了对每个双圈连通图G,l(G)=△ 1或△ 2.这个工作推广了[1]中的一个结果.此外,我们还给出了双圈连通图的no-hole L(2,1)-labelling的存在性.     

Compositional change in human enamel irradiated with MIR free electron laser

The purpose of this study was to investigate compositional changes in human enamel irradiated with the free electron laser (FEL).The exposure on dental enamel at the wavelength of 9.64μm was observed with the Beijing free electron laser.The distribution of elements in the irradiated or non-irradiated enamel was measured by scanning electron microscope (SEM) with energy-dispersive spectroscopy and synchrotron radiation X-ray fluorescence(SRXRF) in Beijing Synchrotron Radiation Facility (BSRF).The results showed that the P/Ca ratio in the ablation region of enamel at the maximum wavelength of infrared absorption of enalmel at the maximum wavelength of infrared absorption was obviously smaller than that at the non-maximum wavelength.In the ablation region the ratios of P/Ca and Ca/Sr were smaller than those in the non-ablation region.The distribution of P,Ca and Sr in the ablation region were heterogeneous due to the element change caused by FEL irradiation.

Modeling the THz spectrum of the bentazon

Terahertz (THz) spectra of bentazon are determined within the range of 0.3 2.4 THz at room temperature.Density functional methods are used to compute the THz spectra using three different programs:Gaussian03 for isolated-molecule form,DMol 3 and CRYSTAL09 for solid-state forms.Among the three,the computed THz spectrum of CRYSTAL09 shows better bond length and angle agreements with Xray experimental results,and corresponds with observed THz experiment spectral characteristics.The isolated-molecule vibrational mode values are less by half than those derived from solid-state calculations.The last five peak positions of the two solid-state computations coincide with each other.Moreover,all the experimental THz absorption peaks are assigned by utilizing CRYSTAL09.
