摘　　要：设计一套可以观测重金属运移的装置,实验发现:当重金属中加入U、Th等α放射源后,放射源的α衰变能够使重金属产生明显的向上运移,这是因为重金属与He核形成团簇,当团簇的密度比空气小时,重金属团簇便可以向上运移。A device available to observe the heavy metal＇s migration is designed. We discovered that mixed with α-radioaetive source such as U, Th etc. , the heavy metal processes the obvious upward migration ability because of α-disintegration. The heavy metals and He nuclei can come into being Cluster. When the specific gravity of Clusters is smaller than that of the air,the Clusters of the heavy metal have the ability of upward migration.
