原子核和电子等带电粒子非常小,例如原子核的直径只有10-13~10-12厘米,肉眼是 看不见的。多少年来,科学家们一直在想方设法看到它们的踪迹。过去用一种“云室” 去观察,但看不太清楚。 1952年的一天,26岁的物理学家格拉塞在紧张工作之余,打开了一瓶啤酒。啤酒 冒出一串串气泡,他还在想刚才的实验,竟忘记了喝啤酒。过一会儿,气泡渐渐不冒 Charged particles such as atomic nuclei and electrons are very small. For example, the diameter of a nucleus is only 10-13 to 10-12 cm, which is invisible to the naked eye. For many years, scientists have been trying to find their way. In the past, a “cloud room” was used to observe, but it was not clear. One day in 1952, 26-year-old physicist Glaser opened a bottle of beer while working hard. A string of bubbles appeared in the beer. He was still thinking about the experiment and forgot to drink beer. After a while, bubbles do not take off
