孔明灯实际上就是一种微型纸质热气球,是靠热空气密度比较小,把气球升上高空的。春节放孔明灯,有时还挂上一小串鞭炮,让孔明灯带到空中燃放,特好玩。做孔明灯也有许多科技知识,在制作过程中,要边做边思考边改进。做好的孔明灯如图1所示(当然形状可以创新)。它由3部分构成:一是“气球”,它由一个正方形的顶和4个侧面粘贴而成;二是燃料支架,它由竹片做成一个圆圈,中间由十字架固定;三是杯状燃料网框,它 The Kong Ming Lantern is actually a miniature paper hot air balloon. It is based on the relatively small density of hot air and lifts the balloon up to high altitude. In the Spring Festival, lanterns were placed on the lanterns, and sometimes a small string of firecrackers was hung. There are also many scientific and technological knowledge for doing Kong Ming Lan. In the production process, we must make improvements while thinking. The well-made lamp is shown in Figure 1 (of course, the shape can be innovative). It consists of three parts: one is the “balloon”, which is made up of a square top and four side sticks; the second is the fuel bracket, which is made of a circle made of bamboo, with a cross fixed in the middle; third is the cup fuel Frame, it
