CORBA构件具有很好的封装性和重用性,并且支持大规模软件复用技术.基于CCM的软件体系结构模型,在行业趋势引导下应运而生,并在技术上具有实现的可能性.基于CCM的软件体系结构模型的核心内容包括其组成结构和特点两个方面.该模型的软件开发主要包括UML分析、ADL和CIDL生成、软件体系结构和软件构件生成三个阶段.     

蒸汽发生器排污管嘴压降研究及蒸汽发生器管板排污孔设置方式探讨

本文通过对蒸汽发生器管板排污流道(包括排污管嘴)进行有限元建模分析,利用STAR CCM+程序模拟蒸汽发生器管板中实际流动情况,得到管嘴出口处压力值,为计算蒸汽发生器排污管嘴阻力系数K值提供有力支持。本文同时利用STAR CCM+对蒸汽发生器管板排污孔不同数量和不同位置分布的三种设置方式进行有限元模拟,探讨三种不同设置下近管板平面流场分布和排污能力差异。本文最后对三种不同排污孔设置下排污管嘴K值进行比较分析,综合探讨考虑排污效果、避免闪蒸两类因素下,排污孔最优设置方案。     

Salespeople as information gatherers: Associated success factors

Salespeople are in a vantage position to have intimate knowledge of the customers. How to motivate them to be effective information retrievers becomes a challenge to sales managers in today's knowledge economy. This paper presents the results of a study into managerial factors that are associated with more effective information retrieval by sales forces for use in their CRM systems. Sales executives (n = 150) responded to a mailed survey describing the importance of a set of activities to their recruiting/selecting, training, supervisory processes and the climate in the organization generated by upper level management. Results show that supervision and upper management support associate significantly with the effective information retrieval of salespeople; while training those more technically savvy sales recruits results in more effective information retrieval.
