铁磁谐振产生的原因及消除方法分析

1谐振过电压概述谐振过电压一般分为线性谐振过电压、铁磁谐振过电压和参数谐振过电压。线性谐振过电压是电力系统中最简单的一种谐振形式,其特点是电感和电容都为恒定的常数。其谐振过电压数值一般小于额定电压的两倍。参数谐振过电压是由于水轮发电机(凸极机)的同步电抗在直轴与交轴之间周期性的流动,以及水轮发电机或汽轮发电机当定子磁通发生变动时,引起电抗周期性变动,这时如果外电路容抗和发电机的同步电抗相等,就会出现电流电压谐振现象,使发电机的端电压和电流幅值急剧上升,这种现象不仅威胁电气设备的绝缘,而且也影响发电机的并列…

Predicting College Students' Participation in Required Psychology Experiments.

While running a study of college-student subjects recently, I made a serendipitous discovery which may be of use to other experimenters. It is that scores on the Revised Social Responsibility Scale (RSRS) (Berkowitz & Daniels, 1964) discriminate significantly between students who appear and fail to appear for experiments. These findings are discussed in detail. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Genes, Race, and Psychology in the Genome Era: An Introduction.

The mapping of the human genome has reawakened interest in the topic of race and genetics, especially the use of genetic technology to examine racial differences in complex outcomes such as health and intelligence. Advances in genomic research challenge psychology to address the myriad conceptual, methodological, and analytical issues associated with research on genetics and race. In addition, the field needs to understand the numerous social, ethical, legal, clinical, and policy implications of research in this arena. Addressing these issues should not only benefit psychology but could also serve to guide such thought in other fields, including molecular biology. The purpose of this special issue is to begin a discussion of this issue of race and genetics within the field of psychology. Several scholars who work in the fields of genetics, race, or related areas were invited to write (or had previously submitted) articles sharing their perspectives.

Graduate Students' Perspectives of Academic Positions in School Psychology.

An increasing number of vacancies in school psychology academic positions and the reduced number of applicants seeking to enter academia have created projected shortages in academe. The purpose of the current study was to determine perspectives of academia held by current school psychology graduate students, who are in line to become the next generation of trainers. Based on information yielded from focus groups conducted with graduate students at two major doctoral school psychology training programs, a 42-item survey was designed to assess students' beliefs regarding benefits and drawbacks of an academic position, possible incentives that would encourage one to apply for an academic position, and past and current likelihood of applying for an academic position. Doctoral students from 98 school psychology graduate programs were invited to participate in the study; a total of 236 students returned completed surveys. Results indicated a significant trend toward increased consideration of an academic career as students progress through graduate school. The highest-ranked benefits of an academic career involved roles and activities inherent to the position, as opposed to potential benefits such as salary or prestige. Regarding perceived drawbacks to academia, job stress was ranked as the most significant deterrent, while the area of least concern involved current preparation to assume an academic position. Finally, respondents agreed on several incentives that would be helpful in overcoming hesitancy in applying for an academic position, including reducing politics in the tenure process, increasing salary, and increased availability of academic positions that emphasize applied work. Implications for current trainers are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

On Professionalization in Psychology.

This column comments on an article by Drevdahl in the January, 1956 issue of the "American Psychologist". In his article, Drevdahl offers an analysis of ABEPP in its relationship to graduate training programs in clinical psychology. His basic point seems to be that if ABEPP claims for itself the ability to judge what is "good" and "competent" in psychological practice then it ought to use this knowledge to improve professional training.

Psychology Students' Training in the Management of Potentially Violent Clients.

Client violence has been reported as one of student practitioners' greatest concerns. This study examined counseling and clinical psychology graduate students' exposure to client violence, perceptions of training received in managing potentially violent clients, and confidence in working with this population. Students reported that their training in the management of potentially violent clients was inadequate and that their confidence in working with this population was low. A positive correlation between perception of training and confidence in managing potentially violent clients provides support for more comprehensive training efforts for students in the management of potentially violent clients. Training suggestions are presented. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychology in its world context.

Discusses factors affecting psychology in countries other than the US in terms of national interests and priorities; national expectations; and economic, geographical, linguistic and semantic, and cultural factors. Perceptions of American psychology among other countries are considered, and the effects of interests common to the national psychologies are examined in relation to the exchange of persons, internationally oriented publications, and international and regional meetings and associations.

The Meaning of Race in Psychology and How to Change It: A Methodological Perspective.

The primary purpose of this article was to offer a methodological critique in support of arguments that racial categories should be replaced as explanatory constructs in psychological research and theory. To accomplish this goal, the authors (a) summarized arguments for why racial categories should be replaced; (b) used principles of the scientific method to show that racial categories lack conceptual meaning; (c) identified common errors in researchers' measurement, statistical analyses, and interpretation of racial categories as independent variables; and (d) used hierarchical regression analysis to illustrate a strategy for replacing racial categories in research designs with conceptual variables. Implications for changing the study of race in psychology are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

On Training in Engineering Psychology.

In the April 1961 issue of the "American Psychologist," the Division 21 Committee on Training in Engineering Psychology presented a report covering the scientific and professional aspects of human factors engineering, with special emphasis on training programs intended to provide adequate preparation for specialization in this area. While the underlying philosophy and specific training programs outlined in the article are, in general, satisfactory a few points need to be emphasized and a few critical remarks need to be made. Those remarks are stated in this comment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

On Research in Clinical Psychology.

The author's impression of the factors giving rise to the isolation of research findings from clinical practice is that they do not stem so much from an absence of scientific attitudes or research interests, as they do from qualitative features inherent in much of the research of clinical psychology which do not allow for appropriate utilization of this research in actual practice. There does not appear to be sufficient attention to the peculiar qualitative requirements of clinical research necessary for it to be of optimal value, and the question may be raised as to whether research standards are too lax. We should bring to a close the epoch of clinical research effort aimed at relating few and isolated variables even though the context of such study makes obvious the necessity for comprehensive data collection and analysis. Understanding the "inefficacy" of clinical research appears to necessitate investigation going beyond socio-professional needs and influences into the function of the research activity within the framework of personality. In view of the value and society's investment in research, investigation into the relationship between personality and research activity promises benefits broadly applicable to other professions and situations.
