amount of SiC particles was deposited at the non-woven(C/C-SiC-1) and web(C/C-SiC-2) layer of 2D needle-punched carbon fibre fabric reinforced pyrocarbon composites,respectively.Ablation under......
cotton by agar diffusion method against Staphylococcus aureus and Escherichia coli bacterial pathogens and fungal strains Candida albicans and Aspergillus niger,respectively.关键词:......
of compressibility and permeability from the perspective of soil fabric. The Pb-contaminated KB mixtures for oedometer tests and sedimentation tests were prepared with bentonite contents of 0, 5%, 10... concentration. It is concluded that the fabric of KB mixture, depending on the particle-particle interaction subjected to different ranges of pH and Pb concentration, governs the sedimentation behavior......
was fabricated by using the cotton as biotemplate, through cerium nitrate solution infiltration and thermal decomposition. Field emission scanning electron microscope (FESEM), powder X-ray diffraction (XRD... numerous efforts have been directed to the synthesis of hierarchical microtube, few researches have been concerned with ceria material. We chose the plentiful agricultural product, cotton......
, the multilayer reinforced fabrics are subjected to the following procedures: pattern design, cutting and sewing. Considering the fabric properties, the 3-dimensional CAD software and sewing machines, which... As an example, the following procedures demonstrate how to finish a rotor preform from carbon-PEEK fabric. 2.1 Pattern design In this process the 2-dimensional pattern will be calculated from cubic......
to cotton structure, and carbon polyhedron with dimension of 50-250 nm and shell thickness of 15-30 nm. The change of solid spheres to hollow polyhedron with branches gives a new evidence for formation... at 2 300 ℃. HRTEM image in Fig.3(b) reveals that the curled carbon sheets entangle like cotton structure with many spaces between cottonwoods. Through HTT, the disordered carbon sphere transforms......
) nonwoven fabrics. Surface modifications of the fabric were performed by using a chemical modification procedure where carboxyl groups were prepared on the PET surface, a coupling agent was grafted......
基于区块链的电力数据资产化及交易系统设计王柯元1,2,于雷1,颜拥3,孙毅1,21. 中国科学院计算技术研究所2. 中国科学院大学计算机科学与技术学院3. 国网浙江省电力有限公司电力科学研究院摘 要:在传统的中心化数据交易系统中,电力数据类的敏感数据存在因可复制而易被滥用等问题.为此,设计了基于区块链技术的电力数据资产化及交易系统.利用区块链技术的密码算法,多中心对等架构,分布式多方共识协议,使参与记录数据交易信息的多方实体仅需通过对区块链技术的信赖建立多方信任关系.该系统以超级账本项目的 Fabric联盟链为框架,借助区块链的技术特性实现了电力数据交易业务的安全,透明,可追溯,不可篡改,并加入了监管机制.该系统实现了应用层Web服务的开发,便于使用.对该系统在一台设备上模拟多节点部署进行测试,结果表......
resistance and low coefficient of friction.Bidirectional(BD) satin weave polyacrylonitrile(PAN)based carbon fiber(Cf) fabric preform was successfully infiltrated with Al 6061 alloy by squeeze infiltration......
studied, and the genesis of deposit was researched combined with the ore-forming material source, mineralization type, mineral assemblages and mineral fabric, wall rock alteration and pattern......
