1引言滴水起电机最早是由开尔文发明的,又名开尔文滴水起电机.它十分简单、便于制作,却含有丰富的物理思想,可是在实践中发现材料的选择和细节安排的不同会直接影响实验的成败,为此进行了大量的对比试验,制作了一种材料易得、制作简单的滴水起电机简易装置.此装置增加了滴水管的固定与底部绝缘部分,水中加入红色钢笔水,且水管加细使喷泉现象更明显,一经制作完毕,以后使用可无需调节,只需加水便就可成功演示.它集科学性与趣味性于一身,十分适用于中学教学演示,更可让学生自己制作,既锻炼动手能力又能激发其对科学的兴趣.
1 Introduction The dripping motor was originally invented by Kelvin, also known as Kelvin dripping motor, it is very simple, easy to make, but rich in physical ideas, but in practice found that the choice of materials and the details of the arrangement will directly affect the experiment Success or failure, for which a large number of comparative tests were made to produce a simple material easy to get ready, simple device for dripping motor.This device adds a fixed drip pipe and the bottom of the insulation part of the water to join the red pen water, and water pipes It is more scientific and interesting, it is very suitable for middle school teaching demonstration, but also allows students to make their own , Both exercise ability and stimulate their interest in science.
