在欢腾的节日夜晚,凌空爆发的烟花,五彩缤纷,鲜艳悦目,给节日增添了欢乐的气氛,抬头仰望,我们最初看到的是一个迅速向外散射的绚丽光球,然后才慢慢散落下来。凌空爆发的烟花开放时为什么会呈现散射的光球?近年来杂志上发表了一些讨论文章,但这些文章都是假定竖直发射的烟花升到最高点时才爆发,这是特殊情况。一般情况怎样呢?《物理通报》1986年
On the jubilant holiday night, the volcanic fireworks that broke out in the sky were colorful and bright, adding a joyous atmosphere to the festival. Looking up, we first saw a brilliant ball of light that scatters quickly and then slowly scattered. Why do scattered volcanic fireworks appear when volleyballs burst into the air? In recent years, some articles have been published in the magazine. However, these articles are based on the assumption that vertical fired fireworks will only erupt at the highest point. This is a special case. What is the general situation? “Physics Bulletin” 1986
