全国政协委员、中国快递协会会长高宏峰:要让快递车辆进城不再难

正"快递业的发展创造了一种新的物流形态,以快递为线,把物流、资金流、信息流有效融合起来,这会形成一个很大的产业链。"3月5日,全国政协委员、交通运输部原副部长、中国快递协会会长高宏峰在接受记者采访时表示,要高度重视快递行业,化解快递车辆进城难等问题,用规模化、规范化、标准化推进快递行业的发展。目前,我国快递业发展迅速,但依然面临很多困难。"很多城市对快递车辆进城采取了严格限制,快递企业只能采用改装后的小型客车在城     

Fabrication and Interfacial Structure of Ni-YSZ-LSM Porous Scaffold for Solid Oxide Fuel Cells

A novel process route using tape casting and stacking for fabricating porous scaffold of solid oxide fuel cells (SOFC) was demonstrated. The linear shrinkages of anode (Ni-YSZ, YSZ stands for 3% Y_2O_3(mole fraction) stabilized ZrO_2) and cathode (LSM-YSZ, LSM stands for La_(0.8)Sr_(0.2)Mn0_3) were optimized to be uniform with that of electrolyte during sintering, by controlling the content of pore former. The micromorphology and interface microstructure of the cross-section of the porous scaffold were observed by optical microscope and scanning electron microscope, respectively. The element distribution and phase composition were analyzed by energy dispersive spectrometer and X-ray diffraction, respectively. The results showed that the porous scaffold with regular pore shape and high specific surface area was obtained after sintering at 1 350℃. The fabricated porous scaffold had defect free interfacial structures due to the uniform shrinkage of anode, cathode and electrolyte layers. In addition, it was shown that diffusions of Zr, Ni and La caused a progressive boundary between YSZ, Ni-YSZ and LSM-YSZ layers. The interface between anode and electrolyte (Ni-YSZ/YSZ) was mainly composed of Ni, YSZ and a small amount of NiO, and the interface between cathode and electrolyte (LSM-YSZ/YSZ) was mainly composed of YSZ, LSM and a small amount of La_2Zr_2O_7.

Cost-benefit of interface management improvement in design-manufacturing chain

Design-manufacturing chain (D-MC) is the most important link of the supply chain with the greatest possibility in cost reduction. How to strengthen the effective management of interfacial relationship between designer and manufacturer and increase the efficency of interface management concerns the efficiency of the whole supply chain. In order to evaluate and improve the impacts of D-MC interfacial relationship, first we should construct the evaluation index system and then we should analyze the total cost and benefit of the interfacial relationship betterment, including the cost of member units in D-MC, the opportunity cost of cooperation partners, and the market returns resulted from the interfacial relationship improvement, which will advance the whole supply chain efficiency as well as enhance the management performance of D-MC.

筋土界面摩擦特性影响因素分析

以整体式单向聚乙烯土工格栅与钢塑复合加筋带为加筋材料,以含细粒土砂为填料,设计了高速公路拓宽工程加筋边坡。通过室内拉拔试验对填料在不同含水量和不同压实度条件下与土工格栅之间的摩擦特性进行分析,并对比了原样土工格栅、去除横肋的土工格栅和土工加筋带三者之间的界面摩擦特性。分析结果表明:在填料含水量高于填料的最佳含水量时,筋土界面强度随着含水量增加而降低,且变化明显,随着填料压实度的提高而不断增强,加筋效果也明显增强;土工格栅的横肋对筋土界面特性影响非常明显,贡献率高达50%以上。
