1·The number above the beginning of each trace is the source azimuth and below is the epicentral distance.
每条轨迹起点上的数字是震源方位角与震源深度。
2·The similarities are similar epicentral distance, similar waveform and both with rich seismic wave groups.
震中距相近，波形相似，地震波组列丰富。
3·The effects of magnitude and epicentral distance on long period spectral components are not so stronger as for…
震级和震中距对短周期反应谱影响明显，对长周期反应谱也有一定影响。
4·Empirical formulas between magnitude, anomalous area of the autocorrelation coefficients and epicentral distance for every station are statistically obtained.
统计得出了各台所对应的地震震级与自相关系数异常面积和震中距的经验公式。
