机械振动与机械波一章,容易混淆两个概念(振动和波动)、两个图象(振动图像和波动图像)、两个距离(波运动的距离和质点运动的距离);容易忽视将振动和波动结合起来分析问题;容易漏掉的是分情况讨论产生的多解。本文从两个典型问题入手,着重对以上易错点加以解析。 Two chapters (Vibration and Vibration), two images (Vibration and Vibration), two distances (distance of wave motion and distance of particle movement) are easily confused with the concepts of mechanical vibration and mechanical wave; Fluctuations combine to analyze the problem; it is easy to miss the multi-solution to the situation discussion. This article starts with two typical problems and focuses on the analysis of the above error-prone points.
