1997年度大中型钢铁企业节能工作情况综述

第九次节能工作会议后，冶金工业掀起了节能降耗的新高潮。各企业都从本单位 实际出发，狠抓节能降耗工作，节能增效成绩显著。大中型钢铁生产企业全年节能３５０万ｔ标煤，超 出１９９７年初冶金工作会议确定的全行业节能３００万ｔ目标。创造效益２８亿元。     

Generating topological structures for surface models

Rapid prototyping has imposed new requirements on the processing of CAD models. To manufacture an object directly, the model must correspond to a real object and thus represent a closed volume. Its boundary must be continuous and closed, and no cracks or improper intersections are allowed. CAD models cannot always meet these requirements, especially when they are constructed by a surface modeler. The algorithm discussed analyzes surface models and generates a topological structure for them that meets rapid prototyping requirements for a closed volume with a continuous, closed boundary

采集系统中存储技术的研究

随着光纤技术在嵌入式领域中的应用,通信数据量不断增加,高速采集网络上的数据并正确地存储到磁盘上已成为整个系统的瓶颈。本文从系统基本功能模块出发结合生产者/消费者(Producer-Consumer)模型,对多线程并发、直接读写扇区、异步I/O等技术在系统中的应用进行分析;对系统模型进行抽象,用数学方法对系统进行可行性分析。实验表明,数据采集系统中采用多线程多缓冲的方式在性能上有一定的提高。

Influence of content and creator characteristics on sharing disaster-related information on social media

Identifying the key factors of the disaster-related information propagation process can provide decision support for disaster management. This study characterizes the effects of content types, location, and social capital of social media users on the virality of disaster-related information. We found through the Weibo dataset of the Yiliang earthquake that the virality of different types of information can vary on the basis of the social capital of users who post the information. This study fills the current research gaps by examining the individual and joint effects of the content and creator characteristics on the virality of disaster-related information.
