学校成套购进的光具座中有托蜡板一个 ,因托蜡板面积小 ,重力轻 ,且与光具座上的滑块支座无连接固定关系 ,因此在学生做实验时很不稳定 ,更换蜡烛也比较麻烦 ,有时蜡烛粘连歪斜 ,还影响成像的位置 ,考虑到托蜡板的上述不足 ,我制作了一种小蜡烛台 ,经学生实验使用 ,效果很好 . There is a waxing board in the optical bench purchased by the school. Due to the small area of ​​the wax board, the weight is light, and there is no connection and fixed relation with the slider seat on the optical bench, so it is very unstable when the students do experiments. , The replacement of candles is also more troublesome, sometimes the candle sticks skewed, but also affect the imaging position, taking into account the above-mentioned lack of wax board, I made a small candle holder, the students use the experiment, the effect is very good.
