摘要
作者根据在计算机数值计算中的经验,提出了在解地球物理反演中常见的病态方程组时,如何确定所用求解方法中的参数问题,取得较好效果。最后用算例作了说明。
This paper discribes the method to resolve the abnormal equations in geop-hisical deduction.According to the experience from computer digital calculation,the authors provide a efficient way to choose the parameters of abnormal equations in geophisical deduction. This method has bren proved to be successful by routine calculation.Practical examples are also given for illustration.
