本栏目2001年7～8期合刊发表《雪到哪儿去了?》和《采采蝇是睡眠病的罪魁吗?》两篇文章后,引起青年少读者的浓厚兴趣。不少朋友来信参与讨论,并提出了自己的想法、答案,也提出许多问题和疑惑。对大家来信涉及的有关问题。我们再次访问了作者陈焕文博士、乐文俊先生和当时的科考队长中国科学院新疆生态与地理研究所的夏训诚研究员。夏先生表示,陈焕文的文章写得挺好,当时就是那种现象,他写得已经很清楚了; 学生的信是学生的想法,他们可以那样想。到目前为止,“雪是如何消失的”还不能作结论。如果要作结论,还要观察几次。然而,在那个地区下雪是罕见的,很难遇上。所以,对于雪的突然消失,依然是个谜。 This column, published in the 7th to 8th issue of the 2001 issue of “Where Is Snow Going?” and “Tsetse is the culprit of sleep sickness?”, attracted a great deal of interest among young readers. Many friends sent letters to participate in the discussion and put forward their own ideas and answers. They also raised many questions and doubts. Letters to everyone related to the issue. We once again visited the author Dr. Chen Huanwen, Mr. Le Wenjun and the leader of the expedition at the time Xia Xuncheng researcher of Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences. Xia said that Chen Huanwen’s article was very well written. At that time, that was the kind of phenomenon. He wrote it very clearly. The student’s letter is the student’s idea. They can think that way. So far, “how snow has disappeared” cannot yet be concluded. If you want to make a conclusion, you must also observe it several times. However, snowing in that area is rare and hard to meet. Therefore, the sudden disappearance of snow is still a mystery.
