Using the Sato single scattering model, based on the near-field digital seismic records from Shandan seismic station of telemetry network of Gansu province, the change characteristics of coda Qc values of Minle-Shandan earthquake sequence, Gansu Province, in 2003, are studied with loss time of 60 s. The relationship between the Qc values and frequency is obtained. For different center frequency points, the change from of Qc values are different. In develop stage of the frequency, Qc values changed with great fluctuations, and in early and late stages, the changes were weak.
