一、所需器材普通显微镜一台,载玻片、盖玻片,蜡烛,蒸溜水(自来水也可)。二、方法步骤 1.用点燃蜡烛将载玻片的一面中间一小段熏黑。方法是用载玻片接触几下烛焰的内焰(在我做的实验中,没有发生过载玻片被烧裂的现象)。这样,就获得大量颗粒较细的碳粒。 2.在载玻片的背面用湿布擦几下,使其迅速降温,以便使用。 3.在载玻片上被熏黑部分的边缘滴上 First, the required equipment, an ordinary microscope, slides, coverslips, candles, distilled water (tap can also be). Second, the method steps 1. With a lit candle to slide the middle of a small piece of black smoke. The method was to contact the inner flame of the candle flame with a glass slide (in my experiment, no overload slide was burned). In this way, a large number of finer carbon particles are obtained. 2. Wipe the back of the slide with a damp cloth and allow it to cool quickly for use. 3. Dripping on the edge of the smoked part of the slide
