1New forming method of manufacturing cylindrical parts with nano/ultrafine grained structures by power spinning based on small plastic strains显示文摘A new spinning method to manufacture the cylindrical parts with nano/ultrafine grained structures is proposed, which consists of quenching, power spinning and recrystallization annealing. The microstructural evolution during the different process stages and macroforming quality of the spun parts made of ASTM 1020 steel are investigated. The results show that the microstructures of the ferrites and pearlites in the ASTM 1020 steel are transformed to the lath martensites after quenching. The martensite laths obtained by quenching are refined to 87 nm and a small amount of nanoscale deformation twins with an average thickness of 20 nm is generated after performing a 3-pass stagger spinning with 55% thinning ratio of wall thickness, where the equivalent strain required is only 0.92. The equiaxial ferritic grains with an average size of 160 nm and nano-carbides are generated by subsequent recrystallization annealing at 480°C for 30 min. The spun parts with high dimensional precision and low surface roughness are obtained by the forming method developed in this work, combining quenching with 3-pass stagger spinning and recrystallization annealing.XIAO GangFeng XIA QinXiang CHENG XiuQua LONG Hu 2016Science China(Technological Sciences)2016,59,11:6

3Finite Element Simulation on the Spin-forming of the 3D Non-axisymmetric Thin-Walled Tubes显示文摘为 3D non-axisymmetric 的压路机运动踪迹薄墙的试管是一条复杂空间曲线。除与空白的接触引起的压路机旋转以外,压路机和主要锭子在细工品附近旋转,并且也沿着革命半径的方向同时移动。正确地建立金属的有限元素(FE ) 模型旋转的方法基于 MSC。榨渣软件被介绍。就压路机的革命和旋转而言的计算公式被数学推理获得。节省的计算点 m 应该是一 4 多重为旋转 3Dnon-axisymmetric 为在细工品附近的压路机的一条革命强迫薄墙的试管获得形成的最大值。模拟结果为几个旋转方法一致很好到试验性的;最大的错误是不到 +-15% 。Qinxiang XIA Baixiang LIANG Saiiun ZHANG Xiuquan CHENG Feng RUAN 2006Journal of Materials Science & Technology2006,22,2:2
4Efficiency against multidrug resistance by co-delivery of doxorubicin and curcumin with a legumain-sensitive nanocarrier显示文摘Multidrug 抵抗蛋白质(MDRP ) 在肿瘤在 multidrug 抵抗的调停被含有,代表主要障碍到成功的化疗。当 curcumin (杂种狗) 在 MDRP 的表示和功能上施加禁止的效果,为杂种狗和 doxorubicin (纪录影片) 的合作交货的 nanocarrier 被准备通过他们的 synergistic 效果克服 MDR 肿瘤。由于在肿瘤的 legumain 的 overexpression,从这 nanocarrier 的纪录影片的版本侧面被设计是调制的 legumain,它被与 legumain 敏感的肽衔接纪录影片到基本材料(chitosan ) 完成。与 nanoparticles 相比仅仅包含纪录影片,纪录影片和杂种狗的 coadministration 显著地禁止了 multidrug 抵抗(P < 0.05 ) 在一个 multidrug 抵抗的癌症房间模型(MCF-7/ADR 房间线) ,与到正常房间(L929 房间线) 的 cytotoxicity。如此的抑制能在 MCF-7/ADR 原子核被归功于到增加的纪录影片累积。合作交货系统整个延长发行量时间,改进指向肿瘤的效率,肿瘤抑制活动的举起,和 MDRP 表示的抑制展出了好 anticancer 效果。这些数据为癌症治疗揭示了这个合作交货系统的庞大的潜力,特别在 multidrug 抵抗可以发展的以后的阶段。Sen Lin Peiling Xie Mengmeng Luo Qing Li Ling Li Jinzhao Zhang Qinxiang Zheng Hao Chen Kaihui Nan 2018Nano Research2018,11,7:2

14A Study on Spatial Distribution of Commercial Housing Prices in Xiangtan City显示文摘ArcGIS technology is used to study the spatial pattern of housing prices in Xiangtan City,and it is found that the spatial pattern of housing prices shows primary and secondary two-center rings. In Hedong Jianshe Road and near Hexi Jijianying,there are primary and secondary polar nuclei,respectively; the secondary housing price area is located near the east-west and south-north trunk road in the urban area; there are significant regional differences in housing price changes( fastest reduction of prices in the Hedong main center-southwest direction; slow reduction of prices in the main center-northwest,southeast direction; slowest reduction of prices in the main center-northeast direction). In Hexi sub-center,except slow reduction of prices in the Xiangjiang River direction,the prices decline rapidly in other directions. The housing prices exhibit an obvious overall decreasing trend from primary and secondary centers to the suburbs,but there are also exceptions. On this basis,this paper analyzes the driving factors for spatial pattern of housing prices in Xiangtan City,and finds that the spatial pattern of housing prices is mainly influenced by commercial centers,residential environmental conditions,traffic conditions,and urban land layout differences.Jinning XIE Qinxiang SONG 2016Asian Agricultural Research2016,8,9:0
