摘要
氡在理想条件下的空气中运移究竟是什么规律 ,通过在较理想条件下的实验 ,氡在空气中“自身”固有的运移现象是 :自氡源产生氡气开始 ,氡气就具有很强的向上运移能力。其运移规律是 :氡向上运移能力大于向下及横向运移能力 ,并随着运移距离加大 ,与横向运移和向下运移相比 。
The self?migration law of Rn has been systematically studied in lab whose condition is ideal. Some significant phenomena and results are observed. We discovery that Rn has very strong ascending ability at the beginning of the generation and that its ascending ability is larger than the horizontal and descending, even more with the distance increasing comparing with the horizontal and descending.
