本文讨论用P_(11)、S_(11)振幅比资料测定震源参数的可行性问题;文中提出算法原理并以北京、河北地区廿五个台站的不同分布组合构成44种资料采集方式进行人工数据试验。结果表明,在台站甚偏地分布于震中一侧的情况下,本文的方法仍然有效。
This paper discusses the feasibility of using the P_ (11) and S_ (11) amplitude ratio data to determine the source parameters. In this paper, the principle of the algorithm is proposed and 44 data collection methods are constructed by the different distribution combinations of 25 stations in Beijing and Hebei Province Data test. The results show that the method in this paper is still valid in the case where the station is very partial to the epicentral side.
