Recent Developments of Antimony-Based Anodes for Sodium- and Potassium-Ion Batteries

The development of sodium-ion(SIBs) and potassium-ion batteries(PIBs) has increased rapidly because of the abundant resources and cost-effectiveness of Na and K.Antimony(Sb) plays an important role in SIBs and PIBs because of its high theoretical capacity,proper working voltage,and low cost.However,Sb-based anodes have the drawbacks of large volume changes and weak charge transfer during the charge and discharge processes,thus leading to poor cycling and rapid capacity decay.To address such draw...

我国纺织服装制品出口竞争力的SWOT分析

纺织服装产业是我国的传统优势产业。在2005年全球配额取消后,我国纺织服装出口额激增,进一步凸现了我国在这一领域的竞争优势,但在纺织服装产业发展过程中,也暴露出很多问题。从内外环境两个层面、有利与不利两个角度,利用SWOT分析法,对我国纺织服装产业的出口竞争力进行系统的分析,旨在指导我国纺织服装产业趋利避害,继续向良性方向发展。     

考虑老化蠕变耦合作用的土工格栅加筋砂土地基承载力的试验研究

聚丙烯双向土工格栅加筋土技术是一种新型的填土处理方法.但是由于聚丙烯材料本身性质使土工格栅在工作过程中会受到老化和蠕变的耦合作用,对土工格栅加筋土地基承载性能产生影响.本文通过五组平板载荷试验,对比分析了不同工况下砂土地基承载力变化.结果表明,加筋砂土地基承载力高于纯砂地基,考虑老化蠕变耦合作用的土工格栅加筋地基承载力...

Architecture Singularity Analysis of 4-U■S/U■U 5-DOF Parallel Mechanism

Architecture singularity of a parallel mechanism with five degrees of freedom (DOF) is analyzed. Such mechanism consists of a movable platform connected to the base by five active limbs. Four of them are identical 6-DOF limbs and the last one has the same DOF as the specified DOF of the movable platform. Based on the kinematics analysis, two categories of architecture singularities for such mechanism are proposed. Then the sufficient condition for each singularity is researched. Results show that the mechanism is singular when it employs each category of the proposed architecture, provided that it satisfies the corresponding sufficient condition. It can be concluded that the proposed two categories of architecture singularities should be avoided with the following dimensional synthesis of such mechanism.
