摘要
该文针对在用加权最小二乘法确定负指数函数中待定参数时，粗差对参数估值的影响，提出了待定参数的抗差解法，并通过实例证明了这一方法的有效性。
Aiming at the influence of the gross error to the estimated value of the parameter, when determining the undetermined parameters in the negative exponential function using weighted least square method, the paper presents the robust solution of the undetermined parameters. Also, using case histories, it proves the effectiveness of this method.
