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。
In this paper, the influence of the gross error on the parameter estimation when determining the parameters to be determined in the negative exponential function by the weighted least squares method is proposed. The method to solve this problem is presented and the effectiveness of this method is proved by an example.
