1) radon migration
氡气运移
2) 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。

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 。
