摘要
介绍了一种新的全区视电阻率计算方法。该方法利用连分式迭代求解非线性方程技术 ,直接对均匀半空间电偶源瞬变电磁法观测的垂直磁场与电阻率的非线性方程直接求解。利用该数值方法对层状介质进行了理论计算。数值计算结果表明 。
A new scheme to define all time apparent resistivity is introduced.For this method,the solution of a nonlinear monotone function,which is very common in electromagnetic soundings,is obtained via continued fraction iteration technique.Numerical results for layered earth show that the new method can be successfully applied to the definition of all time apparent resistivity which can reflect the real variation of geoelectrical section.
