基于RL78系列Renesas单片机的三相电不平衡度分析

随着现代社会的高速发展,用电设备的种类与数量越来越多,用电负荷越来越大,从而导致电力网络的电能质量越来越复杂多变,对用电设备的影响越来越大。现就如何通过RL78系列Renesas单片机求解三相电不平衡度的方法做了浅析,同时给出了C语言的详细算法思路。     

论述工程施工项目成本控制

施工项目的成本控制,通常是指在项目成本的形成过程中,对生产经营所消耗的人力资源、物质资源和费用开支,进行指导、监督、调节和限制,及时纠正将要发生和已经发生的偏差,把各项生产费用,控制在计划成本的范围之内,以保证成本目标的实现。     

Portable fiber-optic laser-induced breakdown spectroscopy system for the quantitative analysis of minor elements in steel

In this paper, we developed a portable laser-induced breakdown spectroscopy(LIBS) using an optical fiber to deliver laser energy and used it to quantitatively analyze minor elements in steel.The R~2 factors of calibration curves of elements Mn, Ti, V, and Cr in pig iron were 0.9965,0.9983, 0.9963, and 0.991, respectively, and their root mean square errors of cross-validation were 0.0501, 0.0054, 0.0205, and 0.0245 wt%, respectively. Six test samples were used for the validation of the performance of the calibration curves established by the portable LIBS. The average relative errors of elements Mn, Ti, V, and Cr were 2.5%, 11.7%, 13.0%, and 5.6%,respectively. These results were comparable with most results reported in traditional LIBS in steel or other matrices. However, the portable LIBS is flexible, compact, and robust, providing a promising prospect in industrial application.     

论全媒体呼叫中心建设

建立全媒体呼叫中心是指利用通讯系统、互联网和全媒体互动电视系统建立呼叫中心多媒体信息通道,实现网络与客户的多渠道互动,在运营模式上重点引进先进的客户关系管理理念,实现呼叫中心从业务受理型向营销服务型的转型,深度服务客户。本文从系统的体系结构,硬件配置和软件功能等方面,介绍了建设全媒体呼叫中心具备如下战略意义与管理价值。     

小井庄的“电”故事

农村政策放宽以后,一些适宜搞包产到户的地方,搞了包产到户,效果很好,变化很快。安徽肥西县绝大多数生产队搞了包产到户,增产幅度很大。——摘自《邓小平文选》第二卷《关于农村政策问题》
