Ni was effectively recovered from spent electroless nickel （EN） plating baths by forming a nano-nickel coated activated carbon composite. With the aid of ultrasonication, melamine- formaldehyde-tetraoxalyl-ethylenediamine chelating resins were grafted on activated carbon （MFT/AG）. PdC12 sol was adsorbed on MFT/AC, which was then immersed in spent electroless nickel plating bath; then nano-nickel could be reduced by ascorbic acid to form a nano-nickel coating on the activated carbon composite （Ni/AC） in situ. The materials present were carefully examined by Fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy, X-ray photoelectron spectroscopy and electro- chemistry techniques. The resins were well distributed on the inside and outside surfaces of activated carbon with a size of 120 ± 30 nm in MFT/AC, and a great deal of nano-nickel particles were evenly deposited with a size of 3.8 ± 1.1 nm in Ni/MFT. Moreover, Ni/AC was successfully used as a catalyst for ultrasonic degradation of 2.6-dichloronhenol.

采用单辊急冷技术研究了Fe_(67.5)Al_(22.8)Nb_(9.7)三元合金的快速凝固和组织形成规律。当辊速从10 m/s增大到40 m/s时,合金条带厚度减少1个数量级,冷速增加了7倍;辊速为40 m/s时样品形状除规则条带外还出现了鱼骨状条带和球状液滴。... 详细信息

采用单辊急冷技术研究了Fe_(67.5)Al_(22.8)Nb_(9.7)三元合金的快速凝固和组织形成规律。当辊速从10 m/s增大到40 m/s时,合金条带厚度减少1个数量级,冷速增加了7倍;辊速为40 m/s时样品形状除规则条带外还出现了鱼骨状条带和球状液滴。合金显微组织由Nb(Fe,Al)_2和a-Fe组成,随着辊速增大,凝固组织特征发生变化并且显著细化。随着辊速的增大,合金条带近自由面凝固组织则由初生a-Fe相和层片共晶向碎断层片共晶转变,近辊面凝固组织始终由不规则共晶组成。辊速达到40 m/s时,规则条带完全由不规则共晶组成;合金液滴由于获得的冷速相对较低,其凝固组织主要由初生a-Fe相和层片共晶组成,且随着液滴直径的减小初生相由树枝晶向等轴晶转变。

探讨了聚乙二醇(PEG)分子量(400、600、1000、1500、2000、4000和6000)对氯化聚乙烯/聚乙烯醇缩丁醛(CPVC/PVB)超滤膜微观结构及其性能(纯水通量、截留率、机械强度和耐污染性能)的影响。结果表明:PEG分子量小于6000时,CPVC/PVB共混膜断面的指状大孔被疏松的多孔结构取代,PEG达到6000时,膜断面出现指状大孔结构,其微观结构与未加添加剂时的微观结构基本一致;PEG分子量为400和600时,CPVC/PVB共混膜表面为多孔结构,随着PEG分子量的增大,膜表面趋于致密。添加不同分子量PEG,均能使CPVC/PVB共混膜的水通量和耐污染性能大幅提升,其中PEG4000和PEG6000提高最多,但膜的截留率和机械性能略有下降。经过比较PEG6000作为添加剂,CPVC/PVB共混膜的性能较优。

采用行为博弈的分析方法建立行为惩罚机制的博弈模型,从定量分析角度研究侵权方实施侵权行为与不实施侵权行为的效用问题;对该博弈模型进行扩展,建立侵权方与政府监管部门之间的混合策略博弈模型并求解和分析该博弈模型纳什均衡的条件。研究表明,建立国家、监管部门和侵权方三者之间的双重惩罚机制,在加强监管力度的基础上增大对侵权方的惩罚强度,一旦发现侵权行为就对其进行严厉惩罚,可有效减少侵权行为的发生。

本文运用演化博弈理论对监管部门和生产企业之间相互作用时策略行为的动态趋势和稳定性进行了分析。研究发现,这些影响博弈双方行为的要素会影响二者行为交互系统均衡点的稳定性。分析表明,企业投机行为的额外收益过高,监管部门不坚持严格监管等因素都会导致系统向不良状态演化,并在这一不良状态保持一定的稳定性,同时,本文还讨论了系统向良好状态演化的条件,并为管理者提出相关的政策建议。
