摘要

在这项工作中，提出了一种使用时域有限差分（FDTD）技术的有效算法，用于建模氡浓度随土壤结构参数的变化，反之亦然。FDTD模型的开发是基于对多孔均匀介质（即土壤）中氡输运方程的同时求解。这个方程描述了每个孔隙体积单位的氡浓度。将数值结果与文献或理论结果进行了比较。

Finite-Difference Time-Domain Simulations of Radon Transport in Porous Media

In this work, an efficient algorithm, using a finite-difference time-domain (FDTD) technique, is proposed for modeling the variation of radon concentration as a function of soil structure parameters and vice versa. The development of the FDTD model is based on the simultaneous resolution of the radon transport equation in a porous, homogeneous medium, namely the soil. This equation describes the concentration of radon per pore volume unit. The numerical results are compared with those of the literature or with the theoretical ones.
