The Forward Theoretical Expressions Without Analytic Odd Points In Whole Spaces Of Gravity And Magnetic Anomaly

The forward calculation of gravity and magnetic anomalies caused by irregular models, can be divided into three-dimensional bodies and two-dimensional bodies from the body angle; Pressing to solve an domain can be divided into the space domain and frequency domain; The method of press the integral calculus can be divided into the finite element method and boundary element method. The former includes some method, the vertical cuboid element, the pillar element and the surface element again in the finite element. The contents of this text research is the three-dimensional bodies of the vertical cuboid element in space domain.Although, the forward calculation of gravity and magnetic anomalies caused by irregular models made a lot of works, still exists some problem demands to resolve. Literature[11] deduced the forward theoretical expressions without analytic odd points in upper non-source semi-space of magnetic forward. But in the gravity and magnetic exploration, sometimes not only need to solve the problem of the upper non-source semi-space,but need to solve the aside non-source semi-space even the problem of nether non-source semi-space. So the forward theoretical expressions without analytic odd points in whole spaces of gravity and magnetic forward is brought forward in this text. The analytic odd points put forward in Literature[11] is caused by the anti-trigonometric function in the forward theoretical expressions, and discover at the time of doing whole spaces to study, the natural logarithms function will also cause the analytic odd points. This text deduced the forward theoretical expressions without analytic odd points in whole spaces of gravity and magnetic forward, going forward to go to correspond with this foundation of the software develop and the model try to calculate, all obtaining good result.
