1) The Law of Rn Migration in the Air
氡在空气中的运移
2) radon migration
氡气运移
3) Release and migration of radon
氡的释放和运移
4) Radon Migration
氡运移
1.
Firstly,a mathematic model for radon migration through gas-liquid two-phase fluid in loose fragmented radioactive medium is established based on the theories of two-phase flow through a porous medium and radon migration by diffusion and convection.
根据原地爆破浸出采铀采场铀矿堆所具有的松散、破碎和非均匀的特性,将铀矿堆抽象为松散破碎射气介质,基于多孔介质中的气-液两相渗流理论和氡运移的扩散-渗流理论,建立了松散破碎射气介质中氡运移的气液两相耦合作用数学模型,并采用有限差分法求出了模型的数值解。
5) migration of radon

The mechanism of vertic al migration of radon and its daughters is: after α-particles emitted by radon and its daughters decelerate, they become He nucleus.
在此理论基础上建立了氡运移理论分布方程 ,并对运移方程进行了验证 。
