摘要
就地震观测工作中的震级误差问题做了初步探讨分析,指出影响震级误差的原因,不仅与地震观测仪器的频谱特性有关,还与震源辐射的能量谱、震源的应力状态和震源深度的不同以及地震波震相、频率等有关,并对如何减少震级误差提出了措施和建议。
The magnitude deviation is analyzed, and it is found that its causes are related with the frequency spectrum of the observational instruments , the energy spectrum of seismic focus, stress, depth of focus, seismic wave phases and frequency, and suggestion and countermeasures are pointed out in the paper.
