- 利用福建“九五”地震台网和“十五”地震台网的并行条件，对其观测资料的测定位移震级进行对比分析，初步得出二者的位移震级偏差，并分析造成偏差的原因。了解两种观测系统的差异对震级的影响，对测定震级具有参考价值。
Taking full advantage of the parallel operation condition of “the ninth fiveyear plan” system and “the tenth fiveyear plan” systems, comparison researches have been made between the displacement magnitude given by the two systems observation data. We preliminarily got the displacement magnitude discrepancy between the two systems, and also analyzed the causation of discrepancy forming. It is found out that the discrepancy between the two systems affects the determination of earthquake magnitude. This result is useful for reference in determining the earthquake magnitude.
