长期权力感知对谈判结果的影响研究

为了探究个人长期权力感知对谈判结果的影响及作用机制,丰富和创新现有的谈判理论,针对实验被试者设计并实施了一次多事项模拟谈判实验;以实验测量所得的长期权力感知、首次报价、调节作用分别作为自变量、中介变量以及调节变量,探究长期权力感知对谈判结果的影响、首次报价所起到的中介作用以及调节定向的调节作用;结果显示长期权力感知与谈判收益之间具有正向相关关系,首次报价在过程中起到中介作用,但是调节定向的调节作用在其中却并不显著;基于以上研究,长期权力感知更强的谈判者会提出更高的首次报价,从而获取更好的谈判收益,调节定向的调节作用在以后的研究中有待进一步探究。

Multifunctional artificial nacre via biomimetic matrix-directed mineralization

Natural nacre, one of the most studied biological structural materials with delicate hierarchical structures and extraordinary performance, has inspired the design and fabrication of artificial structural ceramics with high fracture toughness. However, to meet the diverse requirements of different applications, future structural materials must be multifunctional with superior mechanical properties, such as strength, hardness, and toughness. Herein, based on the matrix-directed mineralization method for producing biomimetic structural materials, we introduce nanoparticles with different inherent functions into the platelets of artificial nacre via the co-mineralization of aragonite and the nanoparticles. Besides their enhanced mechanical properties, the obtained artificial nacre materials also exhibit different functions depending on the type of the nanoparticles. To extend the versatility of this strategy, the effects of nanoparticles of different sizes and zeta potentials on mineralization are also analyzed. This universal strategy can be applied to the fabrication of other types of functionalized biomimetic structural ceramics that have potential applications in various fields, such as biomedical science.     

微生物燃料电池修复钒污染地下水的响应曲面优化研究

使用响应曲面法, 对单室微生物燃料电池去除五价钒的运行条件进行分析和优化。采用乙酸钠作为单室微生物燃料电池的碳源, 探讨钒初始浓度、COD初始浓度和电解液电导率对五价钒去除率的影响, 三因素三水平的响应曲面分析结果表明, 五价钒初始浓度对五价钒去除率的影响最显著, 其次为 COD 初始浓度, 最后是电解液电导率。利用响应曲面法得到最优实验条件: 五价钒初始浓度为75.44 mg/L, COD初始浓度为1007.48 mg/L, 电导率为11.98 mS/cm, 此时可获得五价钒的最大理论去除率80.31%。验证实验的结果证实了该优化方法的可靠性。研究成果可以促进微生物燃料电池技术在治理钒污染地下水领域的实际应用。     

An M-Objective Penalty Function Algorithm Under Big Penalty Parameters

Some classical penalty function algorithms may not always be convergent under big penalty parameters in Matlab software, which makes them impossible to find out an optimal solution to constrained optimization problems. In this paper, a novel penalty function (called M-objective penalty function) with one penalty parameter added to both objective and constrained functions of inequality constrained optimization problems is proposed. Based on the M-objective penalty function, an algorithm is developed to solve an optimal solution to the inequality constrained optimization problems, with its convergence proved under some conditions. Furthermore, numerical results show that the proposed algorithm has a much better convergence than the classical penalty function algorithms under big penalty parameters, and is efficient in choosing a penalty parameter in a large range in Matlab software.     

市售夏枯草饮片质量调查及评价标准研究

为了对夏枯草饮片质量进行全面的评价和控制,对市售18批饮片进行了外观性状考察、TLC鉴别以及水分、灰分、浸出物检测,建立了夏枯草饮片HPLC指纹图谱和咖啡酸、迷迭香酸含量测定方法,并结合主成分分析和聚类分析方法用于对不同批次饮片的模式识别。结果表明,18批饮片外观性状均符合药典标准,但少有符合传统对优品夏枯草外观的要求。TLC图谱均可检出迷迭香酸;水分、总灰分、浸出物含量均符合药典要求;酸不溶性灰分除3批外,其余符合药典要求,但不同批次间有较大的差异;指纹图谱的整体相似度较高,批次间主要色谱峰峰面积和批次间咖啡酸、迷迭香酸的含量有较大差异。通过上述研究,对市售饮片质量有了初步了解,建议提高外观评价标准,增加指纹图谱质量评价指标。     

An Overview of Kernelization Algorithms for Graph Modification Problems

Kernelization algorithms for graph modification problems are important ingredients in parameterized computation theory. In this paper, we survey the kernelization algorithms for four types of graph modification problems, which include vertex deletion problems, edge editing problems, edge deletion problems, and edge completion problems. For each type of problem, we outline typical examples together with recent results, analyze the main techniques, and provide some suggestions for future research in this field.
