碳限额背景下,考虑到碳减排技术的高成本,双渠道供应链中的制造商倾向于与零售商共担成本以减少企业风险。对制造商和零售商碳减排成本分担冲突问题进行研究,有助于供应链协同减排,促进国家实现碳减排目标。本文针对一个制造商和一个零售商组成的双渠道供应链系统,运用演化博弈模型研究碳限额约束下的减排成本分担及减排策略(投资碳减排技术和购买碳排放配额)选择问题,并分析价格调控机制对演化稳定策略的影响。研究发现:存在(制造商不投资,零售商不投资)、(制造商投资,零售商不投资)和(制造商不投资,零售商投资)三种演化稳定策略;进一步,当引入价格调控机制时,双渠道供应链系统在策略(制造商投资,零售商投资)上也能形成稳定。此外,通过仿真分析验证了上述理论结果,并讨论了不同情形下的产品批发价格、减排技术成本、碳交易成本、成本分担比例对制造商和零售商共同分担碳减排技术成本意愿的影响。

光谱学与光谱分析 2012年第10期32卷 2759-2764页

作者： dong cheng-yu LIU yuan-yuan LIU Yin College of Life and Environmental Sciences Minzu University of China Beijing 100081 China

Based on the self-ordered ring(SOR) fluorescence microscopic imaging technique on a hydrophobic glass slide with Zn 2+ and cetyltrimethyl ammonium bromide(CTMAB) as sensitizer,and poly(vinyl alcohol)-124(PVA-124) and NH 3-NH 4 Cl(pH 10.00) as the medium,a method has been developed for determining sparfloxacin(SPFX) concentrations in chicken serum and residues in chicken tissues and *** the droplet volume was 0.20 μ L,SPFX was determined in the range of 1.38×10-13 ～2.03×10-12 ***-1(or 6.90×10-7 ～1.02×10-5 mol.L-1),and the limit of detection(LOD) was ***-1(or 6.90× 10-8 mol.L-1).The recoveries of SPFX at all different spiked levels are in the range of 90.74%～106.61% when the methanol or acetonitrile were used as extracting agent,respectively,and the relative standard deviations(RSDs) are less than 3.0%.This study expands the applied fields of SOR technique in drug concentrations and residues determination.

Removal of Humic Acid from Groundwater by Electrocoagulation

引用

Journal of China University of Mining and Technology 2007年第4期17卷 513-515,520页

作者： FENG Qi-yan LI Xiang-dong cheng yu-jie MENG Lei MENG Qing-jun School of Environment and Spatial lnformatics China University of Mining ＆ Technology Xuzhou Jiangsu 221008 China

With this study,we investigated an approach of applying an electrocoagulation method for the removal of humic acid from groundwater. Aluminium electrodes were selected in the experiment. Some major experimental factors,such as electrode distance,current densities and pH values were explored. Results suggest that,given a small electrode interval and/or a high current density,a lower pH value leads to an improved removal rate of humic acid. Under acid conditions with a current density 47.6 A/m2,for instance,humic acid concentrations were reduced from 20 mg/L to 0.43 mg/L which resulted in the removal of 97.8% of the humic acid. This encouraging result demonstrated that our electro-coagulation method is effective in the removal of humic acid from groundwater.
