清华、哈佛共办低碳发展与公共政策国际研讨会

2016年11月04日,辽宁省沈阳市,沈阳街头一高楼上矗立的大型温度计吸引众多市民注意。据了解,这个大型温度计有18层楼高。在街头设立巨型温度计是为方便市民。巨型温度计的指示柱并非常规温度计所用的水银等,而是LED材料的灯管。灯管的明灭由连接到钟楼上的百叶箱决定。当百叶箱测得街头的实时气温时,就将数据以电能的形式传给温度感应器,随后温度感应器再将电能转化为灯管的明灭命令。户外的气温越高,电能越“高”,灯管也亮得越多。 window._bd_share_config={"common":{"bdSnsKey":{},"bdText":"","bdMini":"2","bdMiniList":false,"bdPic":"","bdStyle":"0","bdSize":"16"},"share":{},"image":{"viewList":["qzone","tsina","tqq","renren","weixin","isohu"],"viewText":"分享到:","viewSize":"16"},"selectShare":{"bdContainerClass":null,"bdSelectMiniList":["qzone","tsina","tqq","renren","weixin","isohu"]}};with(document)0[(getElementsByTagName('head')[0]||body).appendChild(createElement('script')).src='http://bdimg.share.baidu.com/static/api/js/share.js?v=89860593.js?cdnversion='+~(-newDate()/36e5)]; 《沈阳街头现18层楼高巨型“温度计”》由河南新闻网-豫都网提供,转载请注明出处:http://news.yuduxx.com/shwx/647257.html,谢谢合作! varmediav_ad_pub='mKT2ZB_1366943'; varmediav_ad_width='630'; varmediav_ad_height='200';
