“托里拆利实验”是初中物理教学的重要内容，但是在实验中汞对教室环境的污染和破坏却一直存在。为了解决这一问题，笔者对原来教材中介绍的实验装置，做了较大程度的改进，改进后的装置如图1所示，笔者将其命名为，环保型“托里拆利实验”演示器。现介绍如下。1　仪器的构造 The Torrico Experiment is an important part of junior high school physics teaching. However, in the experiment, the pollution and destruction of the classroom environment by mercury have always existed. In order to solve this problem, the author has done a great deal of improvement on the experimental device introduced in the original textbook. The improved device is shown in Figure 1. I named it as a demonstration of the environment-friendly “Torreli Demo” experiment. Device. The introduction is as follows. 1 The structure of the instrument
