First-principles Study on the Ductility Effect of Zirconium and Its Distinct Behavior from Boron to Restrain Hydrogen-induced Embrittlement in Ni-Ni3Al Alloys

Journal of Materials Science & Technology 2008年第2期24卷 165-171页

作者： yuxi wu Yuanming WANG Shenyang National Laboratory for Materials Science Institute of Metal Research Chinese Academy of Sciences Shenyang 110016 China Anhui University of Technology Graduate School of AHUT Maanshan 243002 China

By studying a cluster model containing Ni region （phase）, NiaAI region （phase） and Ni/Ni3Al region （interface） with a first-principles method, the occupation behavior and the ductility effect of zirconium in a Ni-Ni3Al system were investigated. It is found that zirconium has a stronger segregation tendency to Ni region than to Ni3Al region. The bond order analyses based on Rice-Wang model and the maximum theoretical shear stress model, however, show that zirconium has different degrees of ductility effect in these three regions, which originates from its different ability to increase the Griffith work of interracial cleavage 2γint and to decrease the maximum theoretical shear stress τmax. In addition, it is revealed in this paper that the distinct behavior of zirconium from boron to restrain hydrogen-induced embrittlement can be attributed to their different influences on the crystalline and electronic structures in Ni-Ni3Al alloys.

Graph publishing method based on differential privacy protection

High Technology Letters 2018年第2期24卷 134-141页

作者： Wang Junli Yang Li wu yuxi Guan Min Department of Computer Science and Technology Tongji University Shanghai 201804 P. R. China

There are growing concerns surrounding the data security of social networks because large amount of user information and sensitive data are collected. Differential privacy is an effective method for privacy protection that can provide rigorous and quantitative protection. Concerning the application of differential privacy in social networks,this paper analyzes current trends of research and provides some background information including privacy protection standards and noise *** on the privacy protection of social network data publishing,a graph-publishing model is designed to provide differential privacy in social networks via three steps: Firstly,according to the features of social network where two nodes that possess certain common properties are associated with a higher probability,a raw graph is divided into several disconnected sub-graphs,and correspondingly dense adjacent matrixes and the number of bridges are obtained. Secondly,taking the advantage of quad-trees,dense region exploration of the adjacent matrixes is conducted. Finally,using an exponential mechanism and leaf nodes of quad-trees,an adjacent matrix of the sanitized graph is reconstructed. In addition,a set of experiments is conducted to evaluate its feasibility,availability and strengths using three analysis techniques: degree distribution,shortest path,and clustering coefficients.

The First-principles Study on the Occupation Behavior and the Ductility Mechanism of Zr in Ni-Ni_3Al System with Lattice Misfit

引用

Journal of Materials Science & Technology 2014年第5期30卷 517-522页

作者： yuxi wu Wanglin Zhang Jia Guo Jieshan Hou Xiuyan Li Renzhong Huang Xiufang Ma Qianfeng Zhang Institute of Molecular Engineering and Applied Chemistry Anhui University of Technology Shenyang National Laboratory for Materials Science Institute of Metal ResearchChinese Academy of Sciences College of Physics Science and Technology Shenyang Normal University

The influence of lattice misfit on the occupation behavior and the ductility effect of Zr in Ni-Ni3Al alloys were explored. It is found in energy analysis that the preferable site of Zr between Ni sublattice and Al sublattice will change under different lattice misfit, however, the Zr prefers to segregate Ni phase rather than Ni3Al phase in all lattice misfit range, which makes it impossible for Zr to go into Ni3Al phase to occupy Al sublattice in Ni-Ni3Al system. Bond order （BO） analysis shows that the localized ductility effect of Zr differs in different region, and the comparison between Zr-free and Zr-doped BO analysis successfully explain the mechanism of the embrittlement of Ni-Ni3Al alloys and the ductility effect of Zr.

在清代前中期的顺治至嘉庆朝,有一批来自西方的科学家、技师和艺术家(被称为“技艺之人”)获准为清廷效力。他们进京有一套相对固定的程式,推荐是最为重要的一环。把他们推荐给中国皇帝的途径主要有两条,一是已供职于廷的西洋人,二是广东督、抚。这两条推荐途径交替发挥主要作用,最后发展到只能由两广总督奏报。就推荐方式而言,广东督、抚只有奏报这一种,供职于廷的西洋人主要以奏章形式推荐,有时也会利用在皇帝身边的有利条件进行口头推荐。因清廷缺乏引进西方科技艺术的动力,加之进京效力西洋人几乎是清一色天主教传教士,清代前中期的西洋人才引进经历了一个从积极招徕到限制再到最后停止的变化过程。

为解决个性化的服装样板生成技术中合体性的问题,提出了一种基于三维测量数据的个性化女上装原型样板的生成方法。首先,随机选取1名青年女性进行三维人体扫描,根据人体特征点将三维扫描模型于东丽CreacompoⅡTorso系统中数字人台进行拟合,以得到个性化的数字人台模型。采用该软件对个性化数字人台模型的特征线进行分割和展平,得到二维展平矢量图,并根据二维矢量展平图建立了原型样板的变化规则。最后将原型样衣进行试穿实验,生成的个性化原型能够良好地展现实验对象的躯干形态,验证了样板生成规则的可行性和合体性,为个性化女装样板生成提供了一种新的途径,丰富了三维人体模型的二维原型生成的理论和实践。
