摘要
根据火烧区炮变岩△T磁异常特征,选择均匀磁化多边形体反演模型,采用最优化反演方法圈定火烧区边界;通过阻尼最小二乘法自动迭代反演,减少了这代次数和多解性,提高了解释精度。经理论模型与实例试算,证明了方法的有效性。
y analysing the characters of the △T magnetic anomaly of burnted rock in the fire area,polygonal bodies are chosed for inversion model. The optimizational inverse method has been employed to delineate borders of the fire area. By damping least squares auto-fit,the iterative several times and ambiguity can are reduced,and accuracy is improved. The theoretical models and practical data have illustrated the effectiveness of the method.
