利用大型有限元软件ADINA对地铁车站的地震反应做了初步的研究与分析,重点讨论了平面SV波垂直入射下,不同入射波频率和衬砌刚度对动应力集中系数的影响规律,从而为地下矩形结构的抗震设计提供参考数据。     

Signal Anxiety, Defense, and the Pleasure Principle.

Freud equivocated between 2 notions of defense: defense as directed against unpleasure and defense as the blocking of the energy or cathectic potential of the drive. This preserved the quantitative-energic-biological model of anxiety in defense in the 2nd theory of anxiety, rather than developing fully the experiential- qualitative-psychological model of anxiety introduced by the structural theory. The pleasure principle and not anxiety supplies the motive for defense. Signal anxiety, as the epitome of unpleasure, is the basic goal of defense and not the drives, ideas, other affects, or the superego. Defending against these is the means of accomplishing that goal. Signal anxiety is an ego function with appraisal, alarm, and defensive phases. There are metapsychological and technical implications of this approach.

社会演进的动力机制与文化的作用

之所以社会形态的演进最终可以归结为生产力的发展,是因为在经济、社会系统的反馈控制机制中,最终是以生产力的发展为效果检验标准的。面临知识经济时代的曙光,在关于文化作用的问题上,不允许我们在理念的选择上有丝毫的含糊和犹豫。     

The affiliation motive and perceptual sensitivity to faces.

An attempt was made to predict from imaginative measures of the affiliation motive the frequency with which S selects human faces from similar but nonhuman figures in a perceptual task. The Ss were 93 male undergraduates who responded to pictures with imaginative stories scored for n Affiliation. A month later they were introduced to the perceptual task which required that they state which of 4 figures flashed on a screen was clearest, all stimuli being below the recognition threshold. On each trial 1 of the 4 stimuli was a face and the others were similar but affiliation-neutral. Ss high in n Affiliation recognized faces significantly more frequently than those low in n Affiliation. Thus, the predicted relationship between motivation and the perceptual selection of motive-relevant stimuli was supported. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

货币联盟的动力基础和成本收益分析

货币联盟作为区域货币安排的制度,其定义是特定的国家或地区为了维持各国货币间的固定汇率所达成的一项协议.货币联盟的内涵包括：它作为制度的一般性本质、实施机制（争端和协调）和动力基础,其建立的主要收益是降低交易成本、消除汇率风险、节约外汇储备和增加市场福利,成本则在于货币转型成本、货币主权丧失和经济稳定的效率损失.     

生产实习中学生心理活动的研究

斜槽电机中绕组电感参数的解析计算方法

采用斜槽可以减小电机的齿谐波电压,且可以大幅降低高频的电磁转矩脉动,从而改善电机的性能.由于采用有限元法分析这类电机性能时,计算过程比较复杂,而且比较耗时.因此,提出一种计算斜槽条件下的绕组电感参数的解析方法,基于二维坐标系中的气隙磁动势和磁导概念,利用空间谐波分析方法,计算出各绕组的气隙电感参数.利用所述方法,对比分析了不同斜槽角度对某台同步电机电感参数的影响,并且在一台定子斜一个槽距的同步发电机上进行了实际测试,实测结果验证了该方法的有效性和准确性.     

不同权力谈判者的社会动机对谈判的影响

采用工作面试的谈判任务,对166名大学生按同性别陌生人进行一对一的模拟谈判,考察不同权力谈判者(人事经理与应聘者)的社会动机对谈判双赢的影响.结果发现,人事经理单独具有亲社会动机时与谈判双方同时具有亲社会动机时其联合收益没有显著差异,但比双方社会动机控制组的联合收益更多.回归分析表明,谈判中权力大者的社会动机比权力小者的社会动机对谈判的整合结果影响更大,并且这种影响不依赖于谈判者抱负水平和积极情绪的作用.
