摘　　要：近年来,有关大地电磁响应函数估算中消除偏离误差、减少随机误差、评价结果质量方面已有许多研究。Lienert等(1980)提出的多道相关函数法以下式为基础:In this paper, Lienert's method in the estimation of MT response functions is improved. The test of MT data appears that the improved method is more effective for the diminution of bias error and random error in the estimation of MT impedance tensor and for the synthetical appraisal on data and results.
