为了提高国际交换的“中国地震台临时报告”的质量和速度,我们在近两年的工作中,进一步总结了“用ScS核面反射波求震源深度的方法”取得了较好的效果。地球物理学家古登堡在其“地球的地震活动性”一书中,曾特别提到:在确定地震的五个基本参数中,震源深度h值的求得难以把握和不准确。不久前,美国艾文登博士来华,在论述地震定位这个经典问题时,也重申了由于时距曲线不准(比如使用全球平均模型推算的走时表)所产生的定震源深度h值的不可靠性。他用
In order to improve the quality and speed of the “China Interim Reporting Interim Report” internationally exchanged, in the work of the past two years, we have further concluded that “the method of using the ScS surface wave reflection for the source depth” has achieved good results. Gutenberg, a geophysicist, in his book Earthquake Activity on Earth said in particular that in determining the five basic parameters of an earthquake, the determination of the source depth h is difficult to grasp and inaccurate. Not long ago, when Dr. Ai Wendeng came to China to discuss the classic problem of earthquake location, he also reiterated the unreliability of the depth h of the fixed source due to the deviation of the time curve (such as the travel timetable using the global average model) Sex. He used
