| 摘 要： | 利用对数功率谱方法可以方便地估计磁性体埋深,国内外学者曾成功运用于许多地区磁测资料的深度计算,取得了较好的应用效果.但由于采用计算机等间隔分块,等步长滑动方法来计算,使得计算结果只能反映窗口下地质体的统计平均深度,对精度造成一定的影响.本次将计算过程在可视化环境下实现,根据异常实际情况人工选择窗口的大小和位置,提高了深度计算的精度.在煤火区的应用证实了方法的实用性. |

| Abstract: | The power spectrum method has been extensively and successfully used by geophysicists both in China and abroad to estimate the buried depth of magnetic bodies.However,the estimated results only statistically reflect the average buried depth of the magnetic bodies under the calculation window,and the estimating precision is thus affected as a result of equal window size and equal sliding step in calculation.In this paper,the authors have developed a visualized and high precision program that can select window size and site and sliding step voluntarily.Its application to a coal fire area demonstrates the practicability of the program. |
