摘要 本文用蒙特卡洛模拟法进行磁异常曲面向上延拓。具体说明方法的数学概率模型及随机抽样方法。以磁异常Z为例,对二维和三维理论模型及实测磁异常进行模拟计算,计算结果表明,该方法有较满意的精度,能提供实际使用。方法的优点是程序结构简单,输入数据容易,可在微机上运行。 A method for upward continuation of magnetic anomaly on an uneven surface with the Monte-Carlo simulation is presented. A mathematical probable model and random sampling method are illustrated, too. Take magnetic anomaly Z for example, we calculate 2-and-3dimensional theoretical models with simulation method. The numerical results show that the melhod has a satisfactory precision and can be applied to practice. The method has advantages, such as simple program structure, easy Original data-in, and can be executed on micro computers.
