本刊一九八四年第六期,发表了江苏省教学仪器公司李安福同志的“用气垫导轨演示弹簧振子的简谐振动的方法”一文,这篇文章详细讨论了用气垫导轨演示弹簧振子简谐振动的方法。无疑地,对每一位读者都有很大帮助和启发。但在文章的第一个问题里,谈到如何进行演示时,第一句话就说:“首先把导轨调成水平”。我认为这是一个没有必要的条件,我们不妨可以从导轨成水平状态和导轨与水平成一定角度两种情况分别进行讨论。
The issue of the sixth issue in 1984, published by Comrade Li Anfu, Jiangsu Province, teaching equipment company, “the use of air cushion guideway to demonstrate the simple harmonic oscillator spring vibrator method” article, this article discusses in detail the use of air cushion guide spring oscillator Simple harmonic vibration method. No doubt, for every reader is a great help and inspiration. However, in the first question of the article, when it comes to how to carry out a demonstration, the first sentence says: “First, adjust the guide rails.” I think this is a condition that is not necessary. We may as well discuss the two situations from the horizontal guide rail and the horizontal guide rail respectively.
