贵刊于2008年第二期登载了陈月山老师的一篇文章《一道中考题的背景及解法讨论》,文中对2007年南京市中考第27题的解法及来历作了深入地分析与探讨,相当精彩.文末提到了冯.奥贝尔定理,陈老师希望能寻求一个初中生能明白的证明方法,但未果.笔者深为陈老师的执著与探索精神所折服 In your second issue of 2008, your magazine published an article titled “Background and Discussion of an Intermediate Test Question” by Mrs. Chen Yueshan. In this article, the author made an in-depth analysis and discussion of the solution and origin of the 27th issue of the 2007 Nanjing University Entrance Examination. Wonderful. At the end of the article, I mentioned Von Aubert’s theorem. Teacher Chen hopes to seek a proof method that can be understood by junior high school students. However, it is unsuccessful. The author deeply admires the spirit of Chen’s perseverance and exploration.
