Visible-light-driven photocatalysis as a green technology has attracted a lot of attention due to its potential applications in environmental remediation. Vesicle Cd Se nano-semiconductor photocatalyst are successfully prepared by a gas template method and characterized by a variety of methods. The vesicle Cd Se nano-semiconductors display enhanced photocatalytic performance for the degradation of tetracycline hydrochloride, the photodegradation rate of78.824% was achieved by vesicle Cd Se, which exhibited an increase of 31.779% compared to granular Cd Se. Such an exceptional photocatalytic capability can be attributed to the unique structure of the vesicle Cd Se nano-semiconductor with enhanced light absorption ability and excellent carrier transport capability. Meanwhile, the large surface area of the vesicle Cd Se nano-semiconductor can increase the contact probability between catalyst and target and provide more surface-active centers. The photocatalytic mechanisms are analyzed by active species quenching. It indicates that h＋and UO2^-are the main active species which play a major role in catalyzing environmental toxic pollutants. Simultaneously, the vesicle Cd Se nano-semiconductor had high efficiency and stability.

Fe68Zr20B12 amorphous alloy was prepared by mechanical alloying（MA） method and annealed at different temperatures. Microstructures and magnetic properties of Fe68Zr20B12 alloys as-milled and annealed at 693, 843, 943 and 993 K were studied. The raw powders（Fe, Zr, B） formed b. c. c. α-Fe solid solution at early stages of MA and then transformed into amorphous alloy. Grain size（D） of Fe68Zr20B12 alloys increases with increasing annealing temperature and keeps at nanometer level. The specific saturation magnetization（σs） increases with increasing annealing temperature from 300 K to 943 K, and then decreases with annealing temperature at 993 K because of the precipitation of Fe3B.

随着经济发展的不断加速,工程建设技术也在不断提升,但混凝土结构工程出现裂缝的质量问题仍然存在,也是质量投诉的焦点,给建筑市场带来了较大的负面影响。混凝土质量问题是直接影响建筑物安全性和使用功能的最关键问题之一。混凝土结构大量的应用,沉淀了技术,同时也暴露出了自身存在的一些问题,其中裂缝问题表现的尤为明显。在建设中应该采取有效的措施对其进行控制,特别是避免有害裂缝的产生。本文主要对混凝土结构工程中裂缝成因进行分析并结合成因提出对策,为后续裂缝控制提供思路。

任何文学的接受都离不开特定的传播媒介,而不同时代传播媒介的不同转点必然对文学艺术产生深刘的影响。文学的生产工具从口语到刀刻到手写再到敲击键盘,承载文学的传播媒介从口耳相传到龟甲竹帛到纸版到声像再到互联网。无纸化时代的到来终将是一个不可逆转的历史潮流。如今的文学及其发展现状是:口语媒介时代的“贵族文学”已寿终正寝,书写媒介时代的“精英文学”已被挤到“边缘”,播放媒体时代的“大众文学”则一路高歌,数字媒介时代的“个人文学”正方兴未艾。在认识文学现状的同时,我们需思考文学的未来发展之路,从21世纪必须是环保型、节约型社会的角度去看,无纸化的网络文学有可能将是文学落实科学发展观的一个先锋。

“绘事后素”这一论断,是孔子与学生子夏在解读《诗经·卫风·硕人》时生发的一个哲学和美学命题,是《诗经》特有的文化基因与儒家创始人高超的智慧与理性相激发而进发出的思想火花。这一论题的解读在历史上曾引起不小的争议,众说纷纭,有人说它是一种绘画技法;有人说它是指在白色的底子上作画;有人说它是一种以质朴淡泊的画面效果比喻人的自然朴素之美等等。经学的解读向来是仁者见仁,智者见智的,笔者无意在此评判谁家说得更合理更可信,本文只想从“绘事后素”这一命题中“丽质”与“装饰”的关系,引申考量文艺创作中形与神、主观与客观、内容与形式等主辅互为关系的意义指向。
