摘要
利用高精度的数字地震尾波记录来测定一定区域范围内或地震活动区内的介质品质因素Ｑ，是一项非常有意义的工作。本文介绍了一套方法上较完备和相对规范化的尾波Ｑ值计算软件．运用中国数字化地震台网（ＣＤＳＮ）记录给出计算实例。
It is significant to estimate the quality factor Q of the medium in a given region or a seismic active area using the high-precision digital record of coda waves. A set of software for calculating the coda Q value was introduced in this paper. The method was comparatively complete and normal standard. An example was presented by use of the records from the China Digial Seismograph Network (CDSN).
