自从《物理通报》197年下半年开展《小试管为什么会上升》的讨论以来,实验做得愈来愈精细,问题分析得也愈来愈深刻,不少文章从理论与实验的结合上分析问题,有骨有肉,很受启发。我们也按捺不住激动的心情,做了小试管上升运动的实验并进行了力学分析,写出来参加同行们的讨论。 Since the “Physics Bulletin” in the second half of 197 to discuss “Why test tubes will rise,” the experiments have become more and more sophisticated, and the problem analysis has become more and more profound. Many articles analyze problems from the combination of theory and experiment. It has been inspired by bones and flesh. We also couldn’t help but feel excitement. We did an experiment of rising test tubes and performed a mechanical analysis and wrote them out to discuss with our colleagues.
