为了向学生讲清楚“共振”这部分内容 ,高中物理教材中常常列举火车过桥和轮船减摇等生动形象的事例 ,以帮助学生掌握这部分知识 .然而 ,我们的研究表明 ,高中物理教材的各种版本在关于轮船减摇的问题上存在着科学性问题 .本文对此问题作出探索 .1 问题的提出我们查阅了多个版
In order to clearly explain the “resonance” part to students, high school physics textbooks often list vivid examples of train crossings and ship roll-offs to help students master this part of the knowledge. However, our research shows that high school physics textbooks Various versions have scientific problems on the issue of ship roll-off. This article explores this issue.1 The issue was raised and we looked at several versions.
