 [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%。

Abstract: 文章对我国矿产资源综合利用现状及重要性进行了简要介绍,并对目前在矿产资源综合利用方面存在的问题作一概述,提出了建立矿产资源综合利用监测指标体系的必要性。同时设计了宏观监测指标和微观监测指标,并结合Matlab数学工具对指标数据的采集、处理方面的工作进行了探索。
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。

Abstract:

本文通过运用文献资料法,通过对我国各专业体育院校和综合类体育学院近年来对体育史学科课程开展状况资料的收集,谈一下体育史学科在整个体育学领域的重要性。体育史学科作为体育学的基础学科之一,它具有开阔视野、追根问底以及改观思辨等方面的功效。因此无论在专业的体育院校,还是在综合类体育学院,其基础功用都不容忽视。但是,据近些年来体育院校和综合类大学内体育学院的开展情况来看,却不容乐观。有的体育院校甚至取消了该门学科。本文就体育史学科在专业体育院校和综合类大学内体育学院开展的意义做一陈述,来激发学术界对体育史这一学科的关注。从而让它在教学过程中承担起相应的功用。
By using the documentation method to collect the recent years’ materials about the development of physical education curriculum in our country’s professional sports colleges and comprehensive sports univer-sities, this paper mainly discuss the importance of physical education curriculum to the physical training field. As one of the fundamental curriculum in physical training field, because sports’ history curriculum can widen horizon and enrich mind, its basic functions can’t be ignored in professional sports colleges or comprehensive sports universities. However, it’s in bad condition according to the recent year’s development of physical education curriculum in our country’s professional sports colleges and comprehensive sports universities. Some colleges even had stopped teaching this course. This paper will discuss the significance of teaching sports’ history curriculum in professional sports college and comprehensive sports university to get more concerns from academic circles to this course. Thus it can play well its role in teaching process.
