本文提出一种应用电子计算机解重磁问题的新方法,该方法不同于以往的大部分方法,它不由实测重磁场本身直接进行解释,而是通过位场换算设法构造一个有利于解反问题的新函数,使该函数与异常源地质体各欲求参数间存在比较简单的函数关系,从而将复杂的非线性问题化为线性问题或较简单的非线性问题加以处理,基于这一原理,本文就二维孤立及迭加磁异常的反问题导出一种新方法,具体解法归结为首先建立并求解一个线性方程组,然后对能得到的解和各欲求参数间存在的代数方程,采用比较成熟和有效的相应算法,直接求出各未知参数。方法的正确性用理论模型进行了验证,最后,初步评价了这一方法,并指出将其推广到三维等问题的可能性。
In this paper, we propose a new method to solve the magnetic problem by using computer. This method is different from most of the previous methods. It not directly explained by the measured gravity magnetic field itself, but tries to construct a solution that is good for the inverse problem The new function makes the function and the descriptive parameter of the source of the abnormal source have a relatively simple functional relationship, so that the complex nonlinear problem can be treated as a linear problem or a simple nonlinear problem. Based on this principle, Two-dimensional isolation and superposition of magnetic anomalies, a new method is derived. The solution is as follows: First, a linear system of equations is established and solved. Then the algebraic equations existing between the solvable parameters and the desired parameters are obtained by using the more mature and Effective corresponding algorithm, directly to determine the unknown parameters. The correctness of the method is validated by a theoretical model. Finally, this method is initially evaluated and the possibility of extending it to three-dimensional problems is pointed out.
