杂质对Ti-55.8%Ni SMA低周弯曲疲劳性能的影响

真空感应熔炼时采用高纯氧化物坩埚及石墨坩埚, 保持其他控制参数不变, 得到名义成分为Ti-55.8%Ni的TiNi形状记忆合金铸锭, 经完全相同的加工工艺制备成Φ 1.5 mm的TiNi合金丝材. 用自制试验装置对所得TiNi合金丝材的室温低周弯曲疲劳性能进行评价. 研究发现, 使用氧化物坩埚熔炼所得材料的低周弯曲疲劳性能较使用石墨坩埚得到的材料有显著提高. 杂质成分分析及SEM形貌观察显示合金中第二相夹杂物有所减少, 这是其性能得到改善的主要原因. 采用随机安排对比试验结果的t检验方法可以判断, 氧化物坩埚使用中期所得到TiNi合金的疲劳性能较好. 认为坩埚的连续使用次数过多坩埚材料性能的恶化是造成周期疲劳变坏的主要原因.     

从软件开发项目看管理中的沟通

用任何方法或形式,在两个或两个以上的主体(如人或电脑)传递、交换或分享任何种类的信息的任何过程,就叫做沟通.要完成一个项目,需要具备各种才能和素质的人,由此产生了对组织或团队的需求,因此组织的成员都必须与他人共事.而沟通则是实现"共事"的必要条件.没有沟通就无法传达任务,组员不明确任务就无法工作.沟通要定位清晰,采取恰当的沟通渠道和方式,要以尊重他人为前提进行沟通交流,了解他人的性格个性,多倾听,鼓励,提高交谈技巧,表达要清晰.恰当的、及时主动的沟通能够避免软件项目开发中不必要的失误.

电炉电极降耗机理及工艺研究

石墨电极是电炉炼钢和钢包精炼炉的主要加热部件,但电极消耗也是在炼钢过程中所不可避免的消耗材料.电极消耗成本是电弧炉炼钢的主要成本之一.针对近年来电弧炉炼钢居高不下的电极消耗量,相关领域的冶金炼钢专家对此做了深入分析研究,并取得了很好的效果,降低了电极的消耗.然而与国外先进炼钢生产水平的电极消耗相比仍有相当的差距.为此,针对这一现状对电炉电极消耗机理及国内外研究现状做了综合性的分析研究,旨在为电弧炉电极研究专家及工作人员的系统研究做详细的总结陈述,以便于电极的研究与生产.

浓缩-沉淀法制备铟锡氧化物(ITO)微米棒状粉末的试验研究

文章利用新颖的浓缩析出加煅烧工艺、制备了微米级ITO棒状粉末.借助X射线衍射(XRD)对棒状粉末进行了相结构研究;利用扫描电镜(SEM)对棒状粉末形貌进行了相关的表征;用能量分散谱仪(EDS)以及化学分析方法对粉末的化学成分进行了分析;利用热分析仪(TG-DTA,TG-DTG)对粉末的受热行为进行了相关的表征.结果表明:绝大部分ITO棒的直径位于2～9 μm,而且约95%的棒的长径比大于6;ITO棒中的Sn含量主要富集于表面,而且由棒的表面向核心区逐渐递减,这与Sn的引入方式有关;In(OH)3棒中应该存在含In的硝酸盐或亚硝酸盐;In(OH)3强烈的脱水发生在260～280 ℃,随后在更高的温度下形成ITO固溶体.

Statutory remedies to the duty to protect: A reconsideration.

Offers a brief history of duty-to-protect statutes, which limit the liability of psychotherapists who treat life-endangering outpatients and protect therapists who make good-faith warnings when danger to identifiable victims is predictable. Fears are discussed that surround the possibility that courts will continue to expand the Tarasoff (1976) decision beyond its original parameters. Current statutory remedies to problems related to the Tarasoff decision are discussed, and the intent of duty-to-protect laws is examined. Alternative wording to these statutes is offered.

Participation in continuing professional education in nursing: findings of an interview study

The evidence suggests that enrolled nurses and those working part-time and on night duty consistently attend less continuing professional education than their more senior, full-time and day duty colleagues. This was substantiated in the findings of this study which also highlighted the paucity of opportunities for continuing education among unqualified practitioners. In the light of recent developments within the health services, this inequitable provision of continuing professional education to all nursing practitioners will need to be addressed and resolved. Continuing professional education provided on an arbitrary and random basis will not afford maximum positive outcomes for clients, the service and practitioners and has the potential to increase the levels of frustration among disadvantaged groups of nursing staff.     

Motivational forces affecting participation in post-registration degree courses and effects on home and work life: a qualitative study

Over the past decade, pre- and post-registration education for nurses and midwives in the United Kingdom has undergone major change, creating an atmosphere where continuing professional development is a matter of priority for individual health care staff. Against this context of change, and as part of a larger study of continuing education and training in the National Health Service, a cohort of participants in a part-time health studies degree course were interviewed using a semi-structured schedule. Twenty-nine nurses, midwives and allied professional staff described their motives for participation in the course and its effects on their professional and personal lives. Data collected in interviews were analysed using qualitative methods and revealed that participation was encouraged by both professional and personal factors. For many staff participation was prompted by negative feelings about themselves and their professional status. Participation in the course was associated with (largely negative) changes in home and family life and most participants faced additional financial burdens. The findings of the study have implications for policy relating to the funding of continual professional education for nurses and other health care staff. Health care staff are receiving mixed messages about continuing education from policy makers and employers. Dependence on willingness and ability to pay for post-registration degree-level studies is unlikely to be an efficient or equitable means of ensuring lifelong learning for healthcare staff.     

Unintended Consequences: Ventures and Misadventures in the Education of Professional Psychologists.

Increasing professionalization of psychology, accelerated by expansion of professional schools, has evoked concern among critics, who claim that many practitioners ignore scientific research and engage in practices that are demonstrably useless or harmful. Recent data on admissions to professional schools and performance of professional school graduates show cause for concerns of the critics. If psychology is to maintain its stature as a profession, exclusionary controls as well as hortatory requirements for the practice of psychology and the education of practitioners must be established and enforced. Before more stringent standards can be imposed, convincing means for evaluating competence in professional work and quality in professional education must be developed. Local and institutional actions to advance those aims are proposed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
