| Abstract: | 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. |
