流体力学中的伯努利原理是中学物理的一个重要原理。本文介绍了关于流体力学的几个趣味实验的设计原理、制作方法和演示流程,包括气吸球、摇管散花、摇管吸尘器等演示实验。这几个演示实验取材方便、制作简单,实验现象明显,趣味性强,教学效果突出。 The Bernoulli principle in fluid mechanics is an important principle of high school physics. This paper introduces the design principles, manufacturing methods and demonstration flow of several interesting experiments on fluid mechanics, including the demonstration experiment of gas suction ball, shaking pipe and vacuum cleaner. These experiments are easy to draw a few experiments, making simple, obvious experimental phenomenon, interesting, teaching outstanding.
