注射器既是一种医疗器械,又可作为物理演示实验的教具。不仅装置简单、使用方便,而且原理正确、效果明显。有必要加以归纳,发挥它在物理教学中的作用。以下介绍几种应用注射器进行物理实验的演示:一、演示液压机原理
The syringe is both a medical device and a teaching aid for physical demonstration experiments. Not only is the device simple and easy to use, but the principle is correct and the effect is obvious. It is necessary to sum up and play its role in physics teaching. Here are some demonstrations of using a syringe to perform physical experiments: 1. Demonstrate the principle of hydraulic press
