以煤、天然气和氧气为燃料的炼钢技术英国一家公司设计成功一种不用电能而用矿物燃料炼钢的熔炉，它利用高灰分煤（或焦炭）和天然气熔化废钢和直接还原铁，通过高速氧燃烧嘴和喷枪把高品位的氧吹入溶地；该炉集多种高效工艺于一身，如强化熔池搅拌，扩大反应区域，提高供氧速
Steel-making technology fueled by coal, natural gas and oxygen A British company has successfully designed a furnace that does not generate electric energy but uses fossil fuel to make steel. It uses high-ash coal (or coke) and natural gas to melt scrap and DRI, Oxygen burners and guns blow high-grade oxygen into the furnace; the furnace combines a wide range of high-efficiency processes such as enhanced bath mixing, expanded reaction area, and increased oxygen delivery rate

有人说，宝宝的性格是天生的，三岁看大，七岁看老，没办法改变。其实，性格是父母给的——不是先天的遗传，而是后天的影响。 只要宝宝们在一起，无论是在幼儿园做游戏，还是参加大人们的聚会，不出10分钟，各自不同的性格特征便表露无遗。有的宝宝胆小，有的宝宝粗野；有的宝宝怕生人，有的宝宝人来疯；有的宝宝天性温和，有的宝宝则是破坏狂；有的宝宝合群，有的宝宝很快被孤立……有人说，宝宝的性格是天生的，三岁看大，七
