在高中物理实验中 ,气垫导轨广泛应用于牛顿运动定律 ,动量守恒定律等实验方面 .而与气垫导轨配套的微音气泵 ,因其气流均匀 ,流量较大 ,使用方便 ,稍加改进可应用于初中物理流体压强教学中 ,使得实验现象更加明显 ,更加有趣 ,实验效果比较好 .下面介绍几个实际应用供参考 .　 In high school physics experiments, air-cushion guide rails are widely used in Newton’s laws of motion, the law of conservation of momentum and other experimental aspects. The micro-sonic air pump matched with air-cushion guide rails, because of its uniform airflow, large flow, easy to use, a little improvement can be applied In the teaching of physical fluid pressure in junior middle school, the experimental phenomenon is more obvious, more interesting, and the experimental results are better. Here are some practical applications for reference.
