本文通过对山西省台网测定近震震级方法的研究,阐明震级的测定工作在山西省存在的问题和寻求解决的方法。经过对部分地震进行分析,得出影响震级偏差的主要原因,进而求出适合本省台网需要的各台台基校正值,以便提高山西台网测定近震震级的精度。 In this paper, the method of measuring the magnitude of near earthquakes in Shanxi Province is studied, and the problems existing in the magnitude of earthquakes in Shanxi Province and the methods of seeking solutions are clarified. After the analysis of some earthquakes, we can get the main reasons that affect the magnitude deviation, and then find out the Taiwan-based correction values ​​that are suitable for the needs of the provincial network in order to improve the precision of the near-epicenter magnitude of Shanxi station network.
