Using the digital waveform data recorded by 8 earthquake stations around the key hydropower control project area of the Lancang River valley we studied coda attenuation in this area and vicinity with different center frequencies on the basis of coda scattering theory .

利用围绕澜沧 江水利水电枢纽工程地区的8个地震台记录到的数字化波形资料，根据尾波散射理论，以不同的中心频率研究了该地区的尾波 衰减。
