本文甘非均匀物体的磁法与重力勘探直接问题的解,从物体模型和模型引起异常的棍率描述的观点进行了讨沦.付有限物体上的非稳定地球物理场基本特性的确定,提出了三种随机模型:线性的,有任意分布的物理特性和固定源的几何形状;非线性的,有随机参数的单一物体:一个无规则源的集合.由于对那些模型已有非均匀性结构的形式化描述的方法,所以导出的表达式使得异常效应的数学期望值、异常效应的分散和相关函数的计算成为可能. 模型例子用图解说明了随机模拟衬研究干扰体的内部结构的非均匀性范围和干扰体特性付期望异常效应的几率特性影响的应用.这表明异常效应随意性的假设能够用来直接计算最佳的Wiener滤波器,使随机噪音污染的异常形状的恢复以及计算一个依规定精度记录期望异常效应用的观刚间距成为可能.
In this paper, the solution of the direct problem of magnetic and gravimetric exploration of heterogeneous objects is discussed from the point of view of the object model and the model that caused the abnormal rate description. There are three kinds of stochastic models: a linear, randomly distributed physical property and a fixed source geometry; a non-linear, single-valued object with a random parameter: a collection of irregular sources. Since there is already a non-uniform structure for those models So the derived expression makes the mathematical expectation of anomalous effect, the dispersion of anomalous effect and the calculation of the correlation function possible.Examples of the model illustrate the stochastic simulating lining to study the heterogeneity of the internal structure of the interfering body The application of the influence of the probability characteristics of the expected and expected anomalous effects on the range and disturbance characteristics implies that the assumption of anomalous random effects can be used to directly calculate the optimal Wiener filter so that the recovery of the abnormal shape of random noise pollution and the calculation of a dependent It is possible to record the desired spacing for the expected abnormal effect.
