右图拍摄于2012年12月6日中央电视台第13套《新闻30分》栏目。错误原因:“30′”中的“′”是平面角度的计量单位符号,不是时间计量单位符号。应将“30′”改为“30min”。(中国石油吉林石化分公司检测中心刘盾)
The photo on the right was taken on the 13th episode of “News 30 Points” on CCTV on December 6, 2012. The cause of the error: “” in “30 ” is a unit of measure of plane angle, not a symbol of time unit of measure. Change “30” to “30min”. (PetroChina Jilin Petrochemical Branch Testing Center Liu shield)
