中小学人工智能教育的“五心”理念

《新一代人工智能发展规划》发布以来,中国人工智能中小学教育工作提升到了国家战略的高度,越来越多的中小学开始积极探索如何开展人工智能课程设置与教育工作。人工智能课程由于具有内容难度较大、交叉学科较多、知识更新较快等特征,对教授人工智能课程的教师提出了更高的要求。本文认为,从事中小学人工智能教育的教师只有做到定心、大心、专心、虚心和用心,才能将中小学人工智能教育推向更高的层次。

Loading System for Full-Scale Heavy-Duty Support Node Test with Multi-Directional Loading Requirements

This paper presents the design, analysis and experimental study of a loading system for heavy-duty nodes test based on a large-scale multi-directional in-plane loading device, which has been used in a full-scale heavy-duty support node test. Test loads of the support reached 6 567 kN with multi-directional loading requirements, which outrange the capacity of the available loading devices. Through the reinforcement of a large-scale multi-directional inplane loading device, the innovative design of a self-balanced load transferring device, and other arrangement considerations of the loading system, the test was implemented and the loading capacity of the ring was considerably enlarged. Due to the heavy loading requirements, some checking computations of the ring and the load transferring device outranged the limit of the Chinese national code "Code for Design of Steel Structures (GB 50017—2003)", thus elastic-plastic finite element (FE) analysis was carried out on the two devices, and also the real-time monitoring on the whole loading systems during experiments to ensure test safety. FE analysis and test results show that the loading system worked elastically during experiments.

构建广播主持人的品牌影响力

主持人话语是广播表情达意的符号手段,主持人在广播媒体中发挥的作用是无法替代的。广播主持人品牌影响力的构建有助于受众记忆、识别、区别其所在节目及播出平台并持续凝聚受众的注意力。打造全媒体主持人推广平台,加强广播主持人电子有声资料库建设,转化主持人节目产品样态,提升主持人有声语言表达功力,提高可视收音机技术手段和建立科学、常规的主持人评价体系等,都是广播主持人品牌影响力的构建途径。
