我对初中物理课本第一册第十章第二节实验中的图10—9和图10—10的实验用以下装置代替效果很好,介绍如下:1、250毫升装矿泉水空瓶一个,将下端用剪刀剪开后,用一薄胶皮(可用气球)将剪开部分用细线扎紧.(注意胶皮不宜拉得过紧)2、胶塞中间插入一根细玻璃管后将瓶口塞紧,然后用一根长约0.3米像皮管将玻璃管和漏斗连接起来,将瓶子用线挂在铁架台上,如下图.
I have replaced the experiments of Figures 10-9 and 10-10 in the second quarter experiment of the junior high school physics textbook in Chapter 10, with the following devices. The results are as follows: 1. One bottle of mineral water in a 250 ml bottle. Cut the lower end with scissors, use a thin rubber (balloon) to cut the cut part with a thin wire. (Note that the rubber should not be pulled too tight) 2, the middle of the rubber plug into a thin glass tube after the bottle mouth Tighten, and then use a length of about 0.3 meters like a leather tube to connect the glass tube and the funnel, the line of the bottle hanging on the iron platform, as shown below.
