 [PDF]

Applied Physics (APP) , 2013, DOI: 10.12677/APP.2013.32008
Abstract:

本文采用脉冲激光沉积法(PLD)制备了(BiFeO3)0.5:(Sm2O3)0.5/SrTiO3(011)复合薄膜,采用X射线衍射仪(XRD)、能量色散X射线光谱仪(EDX)、X射线φ扫描(XRD phi-scan)和透射电子显微镜(TEM)测试分析了复合薄膜的取向关系、组分、微结构以及界面。并通过“润湿模型”原理结合能量最小化原理推测出了复合薄膜的可能生长结构,发现理论与实验结果相吻合。说明该“润湿模型”可以用来有效的分析讨论复合薄膜的微结构和生长机理。
A (BiFeO3)0.5:(Sm2O3)0.5/SrTiO3(011) composite film has been made by pulsed laser deposition (PLD). Various methods, such as x-ray diffractometer (XRD), energy dispersive x-ray spectroscopy (EDX), x-ray diffraction phi-scan (XRD phi-scan) and transmission electron microscopy (TEM), were used to measure and analyze the orientation relationship, composition, microstructure and interface of the composite film. A possible growth pattern of the film has been speculated by the theory of Wetting Model and Energy Minimization Principle. Analysis shows that the growth pattern is in coincidence with the practical results. The conclusion is that the Wetting Model can be applied to analyze and discuss the microstructure and growth mechanism of composite films.

Abstract:
随着台湾健保制度的改革促使医疗机构面临极大的挑战,故如何有效运用人力资源管理的效能来改善服务质量及提升竞争力是目前医院管理者的重要课题;因此本研究主要将探讨医疗机构之人力资本对人力资源管理效能的影响。本研究在人力资本方面引用了Schuler (1979)提出知识、经验、技能三构面,另人力资源管理效能则是引用曾信超、徐郁茹(2002)分为人力资源确保管理、人力资源开发管理、人力资源报偿管理、人力资源维持管理四构面,并以台湾医院协会人力资源委员会之21家医院为研究对象,每家医院随机抽取10位主管进行问卷调查,有效回收179份。发现人力资源管理效能受人力资本知识与技能显著性影响,且会依医院层级不同而有显著差异,此研究结果可提供医疗机构拟定人力资源策略之参考。
After carrying out the National Health Insurance Project in Taiwan, the healthcare environment is faced with significant change. Therefore, the emphasis on human resource management effectiveness be- comes more important for managers of healthcare organizations to improve the service quality and competi- tiveness. The main objective of this study is to explore the relationship between human capital and human re- source management effectiveness of healthcare organizations. The instruments of this study include two scales; one is the human capital scale developed by Schuler (1979) which comprises knowledge, technique and ex- perience dimensions, and the other is human resource management effectiveness scale suggested by Ceng Xin Chao and Xu Yu Ru (2002) which involves assurance management, development management, recom- pense management and preservation management dimensions. Beside that, this research takes 21 healthcare organizations of Human Resource Committee of Taiwan Hospital Association as objects and adopts the ques- tionnaire survey by collecting 10 questionnaires from each healthcare organization with random sampling. A total of 179 of valid questionnaires were collected. The human capital of healthcare organizations will posi- tively influence its human resource management effectiveness, and
ANTIPHASE DOMAIN BOUNDARY ENERGY OF γ′ [Ni_3(Al,Ti)] PARTICLES WITH VARIOUS Al CONTENTS AND THEIR STRENGTHENING CONTRIBUTION TO A Ni-BASE ALLOY GH99

金属学报 , 1986,
Abstract: GH99镍基合金在室温拉伸变形条件下,被位错切割过渡到被位错绕过的γ'Ni_3(Al,Ti)]质点的临界直径约为60nm.在同样条件下,该合金γ'强化的方式属于被位错切割机制.增加γ'相中Al含量能提高其反相畴界能和增大合金塑性变形的临界分切应力.GH99镍基合金的室温屈服强度理论计算值与实测值很接近.由γ'沉淀强化所贡献的强度占总强度的45%到64%,它随γ'相中Al含量的增多而增大.晶界碳化物强化所贡献的强度很少,只占2—3%。

海洋开发和海洋工程

海洋工程 , 1983,
Abstract: 随着人类社会经济的迅速发展,陆上资源日形衰竭,向面积为陆地2.44倍的海洋进军的要求也就日益迫切。海洋工程为海洋科学调查和海洋开发利用提供手段和装备,是一门新兴的综合性的学科。现将海洋开发的几个主要领域简述如下:
Ti-15-3铸件有希望用于飞机和发动机

材料工程 , 1990,
Abstract: 钛合金铸件早已用作飞机和发动机构件,但一般只用于要求重量轻和强度适中的部位。对于要求强度很高的部位,设计师仍主要依靠沉淀硬化不锈钢,在强度要求很严格的区域,用这种不锈钢来加强钛合金,这就抵消了钛合金重量轻的优点。最新的研究表明,β钛合金有很大的强度潜力,可以使钛合金在强度要求很高的应用中充分发挥重量轻的优势。

网络表情包的亚文化风格构建:从自我表达到公共空间
The Subculture Construction and Transformation of the Network Expression Package′s Discourse Space: From Self-Expression to Public Issues

??
- , 2017, DOI: 10.15896/j.xjtuskxb.201705010
Abstract: 表情包是网络与青年亚文化结合产生的一种新的符号形式。它以娱乐为目的,以拼接、戏仿等为手段,对原材料进行解构与建构,表现出戏谑反讽的风格。表情包不仅是自我表达的工具,而且进入公共领域,融入青年对时事、政治等重大事件的讨论中,成为中国青年参与公共生活的一种新方式。表情包的亚文化属性为青年人讨论严肃议题提供了一个新的空间,然而,其娱乐性及批判的弱化使得对公共议题的讨论深度有限,无法真正触及核心。
With the combination of network and the youth subculture, a new symbolic form which is called expression package has been born. On purpose of entertainment, expression package deconstructs and constructs the raw materials by means of splice and parody, presenting a joking and an ironic style. Expression package not only is a tool of self-expression but also begins a new way for the youth to participate in the public life when the discussed topic is current event, politics or something important. The expression package′s attribute of youth subculture also provides a new space for the young people to discuss some serious issues. However, expression package′s entertainment and the weakening of criticism limits the deep discussions of public issues
黄侃《诗品讲疏》探原

Abstract: 黄侃在北京大学任教期间编纂的《诗品讲疏》是现代《诗品》研究史上的一部知名之作,但学界对其整体内容和相关情况却知之甚少,迄今只能追溯到《文心雕龙札记》中所征引的个别片段。黄侃早年还发表过一篇《诗品笺》,在其身后所刊著述中并未收入,在诸多相关书录、年谱中也从未提及。通过覆核,可知其内容非常接近《诗品讲疏》的原貌,借此可以考察黄侃在研究《诗品》过程中的师承渊源、撰述宗旨、研究视角、个人趣味和教学方法等相关问题。黄侃原有笺疏《诗品》全书的计划,后因悔其少作及兴趣转移等原因而未能最终实现。即便如此,《诗品笺》仍然集中展现了黄侃在《诗品》研究方面的精辟见解,在现代《诗品》研究史上具有开创性的意义。
