The CCTV Media Park Project

中央电视台是中国国家电视台,其新台址工程坐落于最具活力的北京中央商务区,是建国以来国家建设的单体最大的公共文化设施。作为央视新台址工程的重要组成部分,“媒体公园”的规划设计方案强调了央视作为媒体先锋的五个本质意义——“时代、时尚、时下、时段、时机”,在研究人的行为模式的基础上,融合皮拉内西的景观风格,力图建成北京城新的地标景观和城市名片。CCTV, which is China’s National Television Station, has settled down its new location in the most dynamic Central Business District in Beijing. This project will be the largest public cultural facility ever since the establishment of New China. The planning and design for Media Park, the major component of the CCTV New Location Project, highlights the five properties for CCTV’s leadership in mass media, which can be illustrated as time, fashion, update, period and opportunity. This design integrates the Piranesi style and attempts to build a new landmark and urban logo for Beijing

Effects of traditional Chinese medicine on Th17/Treg balance regulation and the role in inflammatory diseases

辅助性T细胞17(TH17)和调节性T细胞(TrEg)是具有密切关联的两种T细胞,它们分别在促进免疫应答和抑制免疫方面起着关键作用,两者此消彼长,协调平衡,是维持人体正常免疫功能的重要组成部分。许多传统中药具有显著的免疫调节和抑制炎性反应的作用,在治疗炎性疾病中具有较大的优势。经查阅国内外相关文献,文章就中医药对TH17/TrEg免疫调节功能的影响及在类风湿性关节炎、溃疡性结肠炎、肿瘤等中的作用进行综述,以冀促进中医药在治疗炎性疾病方面的研究。T helper 17 cells and regulatory T cells are two closely related T cells,which play a key role in promoting immune response and inhibiting immunity.They act as one falls and another rises,keep balance and coordination.They are important compositions for sustaining the normal immune function of human body.Many traditional Chinese materia medica have the effect of immunological regulation and inflammatory response inhibition,which has a large advantage in the treatment of inflammatory diseases.We refered to relevant literatures at home and abroad,and made a review of the effect of traditional Chinese medicine on the function of immunological regulation of Th17/Treg and the role in rheumatoid arthritis,ulcerative colitis,tumor,etc.,in order to promote the research of traditional Chinese medicine treating inflammatory diseases.国家自然科学基金项目(No.81373999); 教育部留学回国人员科研启动基金项目(No.2015-311); 教育部“新世纪优秀人才支持计划”(No.NCET-13-0505)~

PM流量控制器参数对液体静压导轨运动精度影响的研究

液体静压导轨在超精密机床中广泛应用,其运动误差直接影响被加工件表面精度,因此,针对液体静压导轨运动精度的研究并不少见。然而,上述研究涉及的建模方法都具有一定的简化处理,并且少有考虑恒压式液体静压导轨中关键元件节流器的影响作用。基于运动学理论,直接建立四油垫闭式液体静压导轨准静态理论模型,研究PM流量控制器参数对运动精度的影响。分析表明,该节流器三个关键参数不影响运动误差曲线波峰波谷的出现位置,但会影响运动误差的波动程度和PV值。通过油膜反力波动分析可以解释运动误差变化机理,油膜反力波动越剧烈,运动误差变化也越显著。相对于其他两个参数比流量Kr和供油压力Ps,初始流量Q0对运动精度的影响较为显著。研究工作旨在为PM流量控制器关键参数的选取提供理论参考。国家科技重大专项资助项目(2017ZX04022001-207

Critical serrated flow features during nanoindentation in La-based bulk metallic glasses

La57.6Al17.5(Cu,Ni)(24.9) and La64Al14(Cu,Ni)(22) bulk metallic glasses (BMGs) were prepared by copper-mould casting method. Plastic deformation behavior of the two BMGs at various loading rates was studied by nanoindentation. The results showed that the La57.6Al17.5(Cu,Ni)(24.9) BMG with a glass transition temperature of 423 K exhibited prominent serrated flow at low loading rates, whereas less pronounced serrated flow at high rates during nanoindentation. In contrast, the La64Al14(Cu,Ni)(22) BMG with a glass transition temperature of 401 K exhibited prominent serrated flow at high loading rates. The different rate dependency of serrated flow in the two La-based BMGs is related to the different glass transition temperature, and consequently the degree of viscous flow during indentation at room temperature. A smoother flow occurs in the alloy with relatively lower glass transition temperature, due to the relaxation of stress concentration
