摘　　要：本文介绍了基于台阵标定理论建立的上海台阵标定数据库;提出了最近标定和平均标定的方法。通过典型的地震事件对新方法进行了校验,结果表明最近标定和平均标定法的标定效果都比较好,有效的提高了地震定位精度。The establishment of the calibration database in Seismic Array of Shanghai which based on the calibration theory is introduced. Two new calibration methods, the nearest calibration and the average calibration, are presented, and the methods are tested by chosen typical earthquake events. The result shows that both methods are more available and have good calibrate result. By using new methods the location precision of earthquake for the array is improved.
