摘　　要：广东省数字遥测地震台网建成以来积累了较丰富的数字化地震记录,作者利用这些数据开展震源研究,得到新丰江地区的部分地震震源时间函数的初步结果。得到结果的3组地震它们各自较大地震的震级分别为ML1.8、2.3和3.0级,对应的震源时间函数上升时间分别为0.07s、0.09s和0.11s,函数形态较为简单。A lot of earthquakes have been recorded since the Digital Seismic Network of Guangdong Province was established.Certain researches have been made by using of these data.Some source time functions of earthquakes in Xinfengjiang area have been obtained with empirical Green′s function method.The sizes of earthquakes are M_L 1.8,2.3 and 3.0.Their source time functions are very simple pattern and the rise times are 0.07,0.09 and 0.11 seconds respectively.
