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.
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。
In view of more complexity in 3-D, 3-C seismic field operation and high cost of acquisition, the optimum analysis of seismic field acquisition geometry is more important.
鉴于三维三分量的野外作业更加复杂，采集成本更高，因此野外采集地震观测系统的优化分析更为重要。
