摘　　要：本文采用１９８４—１９９２年期间日本气象厅（ＪＡＭ）推算出的大气激发函数序列（χ１，χ２），和美国喷气推进实验室（ＪＰＬ）提供的Ｓｐａｃｅ９３极坐标序列经过反卷积而推出的测地激发函数（ψ１，ψ２）进行了比较。同时也比较了极移（ｘ，ｙ）和从大气激发序列归算出（经过卷积）激发极移（ｍ１，ｍ２）。Atmospheric excitation function series are compared with the geodetic excitation functions derived from the deconvolution of the Space 93 data during 1984-1992 in this paper.The observed polar motion is also compared with the excitation polar motion derived from the convolution of the atmospheric excitation series.
