901铀矿床水文地质特征

901铀矿床为一中型铀矿床。本文着重阐述了该矿床的成矿地质条件、矿床水文地质特征及放射性水文地质特征,指出了该矿床含水性微弱,属简单类型,为以后工作提供了设计依据。     

一种新的35kV简易站远程监控方法

针对35kV简易站运行缺陷,本文提出了一种基于CDA901控制器的农村电网35kV变电站远程监控方法,使得在资金有限的前提下,远程监控系统得以实现。CDA901控制器主要芯片是DSPIC30F6012单片机并能实现三段式过流保护、三遥、重合闸等功能,每个站内均装设有数据汇总装置,该装置把站内所有控制器的数据汇总并转换通过载波机及光纤与调度端联系。该系统在试运行期间取得了良好的效果,改善了电能质量,提高了供电可靠性及电压合格率。     

Attribution—Affect relationships following classroom performance

Two studies that examine distinct affect—attribution linkages in the context of an actual examination are reported. The results provide partial support for Weiner's model but also suggest that attributions are related to positive affect when the attributions are associated with the potential of satisfactory performance. That is, attributions generate positive affect to the extent that such attributions help ensure good performance.
