Theoretical reflection seismograms in dynamite source condition are formed by using anisotropic reflectivity method.
本文用各向异性反射率法计算爆破源反射地震的理论地震图。
Very few seismograms showing motion near to the source are available.
可以利用的记录震源附近运动的地震图很少。
The method of reflectivity in the calculation of synthetic seismograms is extended for the case of a point shear dislocation source buried in a layered medium.
本文将计算综合地震图所用的反射法，推广于层状介质中的剪切位错内源情况。
Then the azimuth of formation fractures is estimated; and with the joint use of zero offset P wave source VSP data, fast and slow shear wave seismograms are obtained to have fracture density.
在获得地下裂隙方位角的同时，结合零偏纵波VSP资料得到快、慢S波记录，进而计算了裂隙密度。
