The result obtained in this study shows that : the source time functions retrieved from p - and s - waves recorded at different stations distributed at different azimuths show prominent directivity 結果表明:從不同方位臺站的z分向p波和sh波提取的震源時間函數(shù)顯示了明顯的方向性效應。
In chapter 3 , the basic theory and method of retrieving source time functions from far - field seismic records to invert for the temporal - spatial source process were expatiated systematically 第三章系統(tǒng)地闡述了從遠場體波提取震源時間函數(shù)( stf ) ,用提取的stf反演震源破裂時間?空間過程的基本原理和方法。
The source time function directivity is in accordance with the p waveform directivity , clearly showing that the nodal plane of strike 199 is the fault plane and that the earthquake ruptured unilaterally from the northeast to the southwest 震源時間函數(shù)的這種方向性效應與p波的方向性效應相一致,清楚地表明:走向為199的節(jié)面為斷層面,地震是從東北向西南方向單側破裂的。
