IBM-PC/XT微型计算机在UPS电源切换过渡特性测量中的应用

本文介绍采用IBM-PC/XT微型计算机构成的一个自动测量系统。这个系统用于采集UPS电源在切换瞬间发生的过渡过程的电压值,并以曲线圈的形式在CRT上显示出来,亦可通过打印机作硬挎贝输出。     

添加沼液养猪的试验研究

沼液喂猪试验表明:添加沼液具有增加食欲、加快生长速度、缩短肥育期、提高饲料利用率(24.4％)、节省饲料,降低养猪成本(24.5％)的优点,在广大农村粗放的饲养管理条件下,沼液喂猪具有较大的推广价值。     

ON THE GENERALIZED RAO-RUBIN CONDITION and SOME VARIANTS

This paper gives a characterization of some members of the compound Poisson family of distributions based on the generalized Rao-Rubin condition. By considering some variants of this condition and using power series arguments, characterizations of the Poisson distribution are also obtained.

Technical Uncertainty in Quantitative Policy Analysis — A Sulfur Air Pollution Example

Expert judgments expressed as subjective probability distributions provide an appropriate means of incorporating technical uncertainty in some quantitative policy studies. Judgments and distributions obtained from several experts allow one to explore the extent to which the conclusions reached in such a study depend on which expert one talks to. For the case of sulfur air pollution from coal-fired power plants, estimates of sulfur mass balance as a function of plume flight time are shown to vary little across the range of opinions of leading atmospheric scientists while estimates of possible health impacts are shown to vary widely across the range of opinions of leading scientists in air pollution health effects.     

透平平面叶栅大负攻角分离流的研究

为了研究透平叶栅大负攻角分离流动的性质,在平面叶栅风洞上对叶栅流道内部及出口半叶高处的流场作了细致的测量,并测得了相应叶高处的叶型表面静压分布。用流动显示方法确定了叶型压力面上的分离区,初步拟出了分离流流型,并用二维时间推进法计算了无分离及有分离时的流场,得到了与实测值较为吻合的叶型表面静压分布及其它流动参数的分布。

Respect,equality, and power: A social psychological perspective

In this article I outline a principled social psychological approach to respect. As a first definitional approximation, I suggest that respect for someone involves the willingness to include that person as a factor in the psychological equation underlying self-regulation. I then review and discuss the fairly recent, but thriving, career of the notion of respect in social psychological research, with particular emphasis on intragroup respect. Next, I turn to conceptual specification and purification necessary for a principled approach to respect and discuss promising efforts to identify the critical social psychological principle or active ingredient of respect. In particular, I make out a case for an equality-based conception of respect in which recognition as an equal plays a central role. The final section examines further theoretical and practical implications of this conception including its relation and relevance to issues of social power. Bernd Simon (Dipl.-Psych., Dr. habil.) is Professor of Social Psychology and Evaluation Research and one of the Directors of the Institute of Psychology at the Christian-Albrechts-University in Kiel (Germany). He studied psychology, sociology and philosophy at the University of Münster (Germany) and the University of Kent at Canterbury (England). In his research, Bernd Simon investigates inter-and intragroup processes, with particular emphasis on issues of identity, power, politicization and respect. He is author/co-author of a number of research articles in international journals and books, including Identity in Modern Society (Blackwell Publishing).
