本文根据黑龙江省台网的实际情况,提出了进行地震定位的圆周扫描法.该方法不去求解观测走时方程组,对台网布局,计算机字长等要求均低于其它方法,因而比较适合黑龙江台网.若干实例表明效果较好.同时稍加改动,也可适用其它台网. According to the actual situation of Heilongjiang Province’s network, this paper proposes a method of circumferential scanning for seismic location. This method does not solve the traveling-time equations and has lower requirements for station layout and computer word length than other methods, so it is more suitable for Heilongjiang Several examples show that the effect is better. At the same time a slight change, but also applicable to other network.
