数智时代,随着全媒体的整合形成,平台媒介井喷式增长的结束,UGC、PGC、OGC等生产模式的完善,加之AI、AR、VR等数字智能技术的出现,以非遗为主题的传播内容不论在数量、范围及效果上均得以增强,并呈现出了一定的转文化传播特质,因此加强非遗传播方向的学术研究愈发重要。本文基于非遗传播实例,以转文化传播的研究视野为切入点,对非遗在日常功能、传播内容、传播渠道及传播主体等四个方面所呈现出的转文化传播特质进行分析,以期厘清非遗传播现状和发展路径,助力非遗的“活态化”传承。

作者： Na LI zhenyu LIU Yiqing qiu Zhaosen LIN Xianghua LIU Guodong WANG State Key Laboratory of Rolling and Automation Northeastern University Shenyang 110004 China

In the present paper, low carbon steel strips with different phosphorus contents were produced using a twin roll strip casting process. The solidification structure was studied and its features were analyzed in detail. It was found that the strips possessed a fine microstructure compared with the mould cast steels. With increasing phosphorus content more ferrite has been formed with finer grains.

随着新能源汽车的蓬勃发展,车辆的驱动系统、车身、底盘控制系统全部电子化,电动汽车运行过程中对外产生的电磁辐射需要进行全面测量。相较于燃油汽车,电动汽车需要额外测量车辆150 kHz至30 MHz频段的汽车电磁场发射强度。通过分析GB/T 18387—2017给出的电动车辆电磁场发射强度的测试布置,深入剖析CISPR 16-2-3:2016中环天线测试距离与测试静区半径的要求,结合乘用车辆车身尺寸的实际测试工况,提出一种全面覆盖被测车辆静区的电磁发射测试场地的验证方法。通过对比两个不同的10米法整车半电波暗室的30 MHz以下电磁发射场地性能,研究结果表明排除暗室自身的谐振频点造成的不确定度,两个暗室的场地性能验证满足使用要求,本文提出的场地验证方法为整车半电波暗室场地性能验证研究提供了一种新的研究思路,供行业参考使用。

为了解中国高原地区农用拖拉机排放状况,加强大气污染物的管控,利用车载排放测试系统(PEMS)对曲靖市中大型农用拖拉机实际工况下的尾气排放情况进行了测试,建立了2021年曲靖市中大型农用拖拉机大气污染物及温室气体排放清单。结果显示,2021年曲靖市中大型农用拖拉机氮氧化物(NO_(x))、CO、CO_(2)、碳氢化合物(HC)排放量分别是3657.165、797.601、175566.573、115.911 t。空间分布结果显示,曲靖市高排放区域主要是农业发达、耕地宽广、农民收入水平相对较高的陆良县、马龙区和宣威市;而城镇化程度较高的主城区麒麟区和地区经济状况较差的会泽县排放水平较低。为尽可能降低排放清单的不确定性,后续工作应针对不同车龄的大型农用拖拉机进行调研和测试,建立本地化排放因子数据库,为曲靖市和其他高原地区空气质量模拟预测与污染治理决策提供数据基础和科学支撑。

近年来,CMS(摄像机—监视器系统,也称为电子视镜)搭载在越来越多的车型上,相对应的强制性国家标准GB15084—2022《机动车辆间接视野装置性能和安装要求》已于2023年7月1日正式实施,该标准明确了CMS应满足电磁兼容性的要求。然而,如何在半电波暗室内搭建测试环境以快速准确读取稳定的CMS系统成像延迟时间目前在国内外都没有解决方案,试验室内机动车辆的CMS窄带电磁抗扰条款测试不利于操作一致性和结果可对比性。为了解决这一安全性评价难题,本论文研究并开发了基于高电磁辐射环境的激励光源与光强传感器的CMS电磁抗扰测试方法,有效地实现了电磁干扰下CMS系统中成像延迟的定量评价问题。
