Physical and Electrochemical Characterization of Hydrothermal Prepared α'-NaV_2O_5 Crystals

引用

Chemical Research in Chinese Universities 2010年第2期26卷 291-293页

作者： HU Fang wei Ying-jin jiang Tao MING Xing CHEN Gang WANG Chun-zhong College of Physics State Key Laboratory of Superhard Materials Jilin University Changchun 130012 P. R. China

a＇-NaV2O5 was prepared by a simple hydrothermal process. X-ray diffraction confirmed the orthorhombic structure of a＇-NaV2O5, with preferential growth along the （001） direction. Scanning electron microscopy showed a＇-NaV205 was composed of flake-shaped crystals. X-ray photoelectron spectroscopy confirmed the co-existence of V^4＋ and V^5＋ in a＇-NaV2O5, which results in an average V^4.5＋ oxidation state of a＇-NaV2O5. The observed Raman bands are ascribed to different V-O vibrations, a＇-NaV205 shows a reversible specific capacity of about 100 mA·h·g^-1 between 3.5 and 1.0 V, with a good capacity retention. The good electrochemical stability of the material is attributed to its structural stability during Li^＋ intercalation.

某用于实验室激光通信实验的转台要求具有±1.5″的定位精度,为了对该高定位精度转台实施检测,搭建了由24面棱体、定心装置、0.2″二维光电自准直仪和支架组成的高精度测角系统,对该测角系统进行了准直误差理论分析。结果表明:多面棱体偏心对定位精度的测量结果影响很小,一般可以忽略,但自准直仪的调整误差对高定位精度的测量影响很大。为了消除该系统误差,在理论分析的基础上,提出了一种基于角度标定的调整误差补偿的方法并进行了实验验证。通过精细调整减小调整误差方法测得转台定位精度σ为0.936″,而采用新补偿调整误差方法测得定位精度σ″为0.922″,σ″相对σ的相对误差为-1.496%,且满足转台定位精度要求。实验结果证明了本文方法的快速性和可靠性。

分析了互联网应用为满足后端存储系统高性能要求而引用的内存键值存储系统的应用特点,指出:为了永久保存数据,这些系统还需要在后端将数据从易失性的内存拷贝到慢速的非易失存储设备中;将新型的非易失存储器件(NVM)引入内存键值存储系统可减少其性能开销;根据NVM的特征,内存键值系统可采用两种架构:将NVM替代磁盘作为二级存储设备和将NVM替代DRAM直接作为主存储设备。基于上述分析,实现了两种NVM架构的内存键值存储系统,并通过实验分析,总结出了内存键值存储系统选择NVM架构的原则,这些原则可有效指导内存键值存储系统在采用当前以及未来NVM器件时,对架构的选择。其次,还通过理论和实验分析,得出了不同架构下的内存键值系统在软件层的主要开销,指出了未来针对这些系统的软件设计的优化方向。

利用世界银行提供的企业调查数据,考察了企业腐败与其内部不同层级人员之间薪酬差距的关系。研究结果表明:企业腐败扩大了CEO与中层管理者、中层管理者与普通员工以及CEO与普通员工之间的薪酬差距;企业腐败的这种效应只存在于内资企业中。以上结论为宏观经济中腐败的收入分配效应提供了微观证据,也为企业内部不断扩大的薪酬差距现象提供了新的解释。

为了推荐在遥感模型评估中引入不确定性的评价指标,即测量学界近年来提出的不确定度A类评定(U_A)。本文通过评估一系列水色遥感反演模型在各类数据集的表现,用计算机模拟了误差的各种近似分布,研究了样本个数n和统计指标RMSE、MAE与U_A之间的关系。算法测试和计算机模拟的结果都表明,在样本个数少的情况下,遥感模型的不确定性(可信赖度)评价用U_A比RMSE、MAE更适合,因为样本个数越多,建立的模型就越可靠(不确定度越小)。此外,本文至少使用50个样本验证遥感模型,可使精度评价更加准确。
