摘　　要：由于最小二乘法不具有稳健性,考虑将降权法与最小二乘法结合,利用降权最小二乘法求解基准转换模型参数。Since the least squares method is not robust, consider combining the decentralized method with the least squares method and using the decentralized least squares method to solve the parameters of the datum transformation model.

关 键 词：降权法 基准转换 最小二乘法
