摘要
从仪器标定、震级公式及分析软件等方面着手,查找出太原台体波震级偏差较大的原因,针对分析软件出现的缺陷问题,重新编制体波震级计算程序,并进行校正。对数字化观测以来的体波震级进行重新计算,给出体波震级偏差统计分析结果及参考校正表。
From aspects of seismograph calibration,magnitude calculating formula and software,causes for larger deviation on body-wave magnitude got from records of Taiyuan Station are figured out.For defects analysis software,program to calculate body wave magnitude is reprogrammed and correction is made.All body-wave magnitudes are recalculated for records since the digital observation.The body-wave magnitude deviation statistical results and corrections are given.
