井下瞬变电磁法中全期视电阻率的牛顿求解法
Newton algorithm for solving full-time apparent resitivity of underground-mine transient electromagnetic method
摘要
Abstract
Solving full - time apparent resitivity is the key step for geological inversion of Transient Electromagnetic Methd (TEM).In this paper,Newton algorithm for solving the root of non-linear function is introduced and then used for solving the full-time apparent resitivity of underground-mine TEM,according the characteristics of the implicit function of the ap-parent resitivity.Meanwhile,the comparison of Newton algorithm and the bisection algrithm indicates that the present Newton algorithm can approximate the full-time apparent resitivity with any accuracy just like the bisection algorithm,but the Newton algorithm may converge much faster than the bisection algorithm.关键词
