题型:选择题 2013年4月10日,清华大学薛其坤院士领衔的中国团队首次在实验中发现量子反常霍尔效应。计算机芯片里的电子毫无规律的从电极一端到另一端,频繁的碰撞、走弯路会造成发热,效率就不高,这是目前晶体管发热的一个重要原因之一。量子霍尔的电子被定义像汽车一样按规则前进,但需要非常强的磁场,成本昂贵而且比较困难。而量子反常霍尔效应的好处是不需要任何外加磁场,因此这项研究成果将推动新一代低能耗晶体管和电子学器件的发展。量子反常霍尔效应的发现表明人们能①改变自然物的具体形态而显示其实践的能动性 ②进行创造性思维以实现科学研究的重大突破③发挥主观能动性突破规律及其适用条件和范围 ④根据主观需要决定客观事物的变化与发展A.①②B.②③C.①④D.③④ 查看答案
