本刊讯受清华大学超导中心主任韩征和教授的邀请,北京大学赵凯华教授于近日前往清华大学超导中心参观。赵凯华教授在参观的同时,向一行人介绍了其2009年发表在《物理教学》杂志上的一篇名为《磁单极子与超导线圈问题的困惑》的论文。他说,当时在中学物理教学中,很多教师为了训练学生,出了大量的题,也把超导和磁单极编成问题。但是由于出题教师对超导的导 This publication was invited by Professor Han Zhenghe, director of the Superconducting Center of Tsinghua University. Professor Zhao Kaihua of Peking University recently visited the Superconducting Center of Tsinghua University. Prof. Zhao Kaihua also visited a group of people and introduced a paper entitled “The Perplexity of Magnetic Monopoles and Superconducting Coil Problems” published in the “Physical Education” magazine in 2009. He said that in the middle school physics teaching, many teachers had made a lot of questions in order to train students. They also made superconductivity and magnetic unipolar problems. However, due to the teacher’s guidance on superconductivity
