摘　　要：自制云室利用上端恒温加热板和底部制冷片在温室内建立较大的温差,能够在短时间快速形成过饱和蒸气层,而且可以长时间观察.整个装置一体化设计,操作时只需加入酒精和放射源,一键开机后短时间内就可以观察到射线的径迹.使用实际生活中的相关物品作为辐射源,观察射线径迹.The self-made cloud chamber uses the upper constant temperature heating plate and the bottom refrigeration plate to establish a large temperature difference in the greenhouse,which can quickly form a supersaturated vapor layer in a short time and can be observed for a long time.The whole device is of integrated design.During operation,only alcohol and radioactive source need to be added.After one button startup,the ray track can be observed in a short time.Use relevant materials in real life as radiation sources to observe ray tracks.

关 键 词：自制云室 射线径迹 观察
