9月18日当我拿到《钓鱼》第18期,正是下午6点多钟了,拿到书翻开目录,发现有两篇论标尾钓文章,翻到一看,是针对我在14期《钓鱼》上发表的那个实验来说的,不由一愣,上次那实验做得好好的怎么会错？可有两位老师同时提出疑问我该再试一下,边走边想。第二天天刚亮,我就拿出上次做实验的工具,来到水池边,(水深约80厘米),重新做实验。这一次浮标直径有1厘米,长有10厘米,按上次实验次序先调标尾轻的一组浮标,后调试标尾比重的浮标,使用结果令我大吃一惊,同一块铅皮,两标尾下降距离相等,与上次结果相左,再试,还是一个结果,重复几次结果都一样,我倒吸一品冷气,真错了！可上次也是试了好几次,纰漏究竟出在哪呢？拿错铅皮了？还是调目不准？不会呀！
September 18 when I got the “fishing” eighteenth, it was 6 o’clock in the afternoon, got the book to open the directory and found that there are two arguments tail fishing articles, turned to see, is for me Fourteen “fishing” published on that experiment, not help surprised a moment, the last time that experiment did well how wrong? There may be two teachers at the same time put forward questions I should try again, think while walking. The next day was just bright, I took out the last tool to experiment, came to the pool edge, (about 80 cm in water depth), re-experiment. This time the buoy diameter of 1 cm, 10 cm long, according to the last experimental order before the end of a small group of buoys tail buoys, tail buoys after debugging the proportion of tail, the results surprised me, with a lead, two tail Decline distance equal, and the last result, try again, or a result, repeated several times the results are the same, I’d suck a product air-conditioning, so wrong! Can be the last time tried several times, what exactly? Take the wrong lead? Still not adjustable? Will not it!
