| 摘 要： | 介绍了有限差分方法的原理,叙述了砂岩型铀矿体上氡气场的分布,并建立了氡气场分布的理论方程,通过有限差分算法求解氡气场分布方程,为砂岩型铀矿体上氡气场的正演研究提供了数值计算方法。针对砂岩型铀矿体上氡气场低值区对应矿体而高值异常场对应矿体两端的特点,以矿体端点高值异常峰值点为中心进行二维等步长剖分,得出差分方程,为问题的进一步研究提供一种算法思路。

| Abstract: | The principle of finite difference method is introduced, and the radon field distribution over sandstone-type uranium deposit is narrated. The radon field distribution theory equation is established.To solve radon field distribution equation using finite difference algorithm is to provide the value computational method for forward calculation about radon field over sandstone-type uranium mine. Study on 2-D finite difference method on the center of either high anomaly radon fields in view of the character of radon field over sandstone-type uranium provide an algorithm for further research. |
