摘要：This paper reports a simple yet efficient method for the synthesis of hierarchical TiO2-B nanowire@α-Fe2O3 nanothorn core-branch arrays based on a stepwise hydrothermal approach. The as-fabricated hybrid arrays show impressive performance as a high-capacity anode for lithium-ion batteries. The key design in this study is a core-branch hybrid architecture, which not only provides large surface active sites for lithium ion insertion/extraction, but also enables fast charge transport owing to the reduced diffusion paths for both electrons and lithium ions. The peculiar combination of attributes of TiO2 （good structural stability） and Fe2O3 （large specific capacity） provides the hybrid array electrodes with several desirable electrochemical features： large reversible capacity （-800 mA.h.g^-1 for specific mass capacity and -750 μA.h-cm^-2 for specific areal＂ capacity）, good cycling stability, and high rate capability. The impressive electrochemical performance, together with the facile synthesis procedure, may provide an efficient platform to integrate the TiO2 nanowire@Fe2O3 nanothorn core-branch arrays as a three-dimensional thin film electrode for lithium-ion microbatteries.

摘要：Layered lithium manganese-rich oxides are promising cathode materials for lithium-ion batteries(LIBs),due to the low-cost,abundant manganese source,and large theoretical ***,these layered lithium manganese-rich oxides,e.g.,monoclinic-LiMn0_(2),suffer from poor cycle performance and rate performance because of fast structural degradation with the irreversible layered-to-spinel phase transition and sluggish electrode kinetics during cycling[1,2].

摘要：为分析埋地钢质管道在河流穿越段承受静态荷载时的力学行为和变形特性,文章选取典型河流穿越段的埋地管道作为研究对象,利用有限元软件建立管道的计算模型,系统研究了不同土体力学参数和埋设深度对管道响应的影响。结果表明:随着土体变形模量的增加,管道的应力和位移均有所降低,且二者之间存在线性相关;而管道的位移随着埋深的增加而增加,管道应力则先随埋深增加而上升,之后趋于稳定。研究结论深化了对复杂地质条件下埋地管道受力和变形机制的理解,为管道的设计、施工和维护工作提供了理论支持,同时对相关工程项目的规划与实施具有参考意义。

摘要：选取丙氨酸为含氮模型化合物,用密度泛函理论(DFT)B3LYP/6-31+G(d,p)基组对丙氨酸高温热解过程进行量子化学模拟计算,设计了三条初反应路径与一条次反应路径,对每条反应路径中的反应物、过渡态、中间体及产物进行几何结构优化和频率计算,分析热解机理。用热重和红外光谱对热解实验释放的含氮气体进行分析,验证模拟结果的正确性。结果表明,初反应是两个丙氨酸分子通过缩合反应脱去水分子生成丙-丙二肽,丙-丙二肽通过缩合反应生成2,5-二酮哌嗪类化合物(DKPs),此路径焓变值小且反应所需活化能最少,为主反应。约290℃时,NH3产率最大,400~450℃时HCN生成量增加,丙氨酸裂解主要的含氮气体产物是HCN,NH3和HNCO,实验所得含氮气体产物与计算结果一致。

摘要：This essay expounds the indiscernible symbiosis that hitches formalist aesthetics to moral consciousness via an analysis of the fictionality of metafiction,the uncertainty of dream narrative,and Sontag’s sarcasm of anti-intellectual behaviors imbedded in her novel The *** fictive nature of the novel is well manifested via the pervasive disclosure of self referential narration made by *** glaring discrepancies between the dreamlike life experiences expatiated on by Hippolyte in the main body of the novel and the circumstances laid plain en masse in his journals,letter,and manuscript which come out at the close of the novel are a strikingly acute revelation to remind a reader of the novel of the uncertainty of Hippolyte’s *** concluding section of the essay is an analysis of Sontag’s satirical version of anti-intellectualism:She arranges for the two abnormal characters—one is fond of daydreaming,and the other is temperamentally“camp”—to revert to the normal way of life and become intellectually *** conclusion of the novel obscurely implies that the realities of the world have rendered it difficult for such a moral disburdenment as is set forth in Sontag’s aesthetic conceptualization to come into being.

摘要：语言具有构建社会身份的作用。广告话语是以某一特定群体为目标,通过刺激、引导来达到销售商品、服务或理念的一种信息载体,是一种特殊的语言形式,同样具有构建社会身份的作用。从批评性话语分析的视角,探究广告话语对我国女性社会身份的构建,以期为广告话语这种特殊语言形式的研究提供新的视角,并促进公众对女性社会身份的正确认识。

摘要：中国绘画美学最早形成于六朝,发展于唐宋,经过元代的转折与衍变,到了明清基本上构成了一个完整的体系。六朝是中国绘画美学的一个关键时期。本文结合当时的绘画创作及相关画论,从三个方面:六朝画家与当时北方宗教艺术的美学思想比较;艺术作品内容与表现形式的统一;六朝画家"以形写神"绘画美学的集中体现,对六朝画家的绘画美学思想做一些初步的分析。
