分析地震波形，标记震相，画图，适合科研人员广大学生及地震同行-it is used for analyze seismic waveform, mark phases,suit for institute member ,grate students of geophysics,and earthquake workers.

用QT写的一个音频波形分析软件,包含频谱分析-A QT based waveform analysis

sac地震波形数据分析作图软件，在linxu平台下拷贝后修改环境变量可用(Sac seismic waveform data analysis and mapping software, after copying under the linxu platform, the environment variable can be modified.)
