本文系统地分析了根据 Lg 波埃里相和非埃里相衰减系数确定单台和台网震级公式、震级标准差以及台站校正值的方法。根据中国东部苏、鲁、豫、皖、冀、浙六省地区约1秒 Lg 波衰减系数的测定结果,导出六省地区的 Lg 震级公式:(?)(?)计算了该区域内19个地震的各震级值,以及80个台站的台校值。单台震级标准差为0.15—016震级单位,台网震级标准差为0.03—0.04震级单位。此外,还测定了111个地震的 m_(mxz)和 m_(mxh)值,验证或补充了19个地震得出的某些关系和结果。
This paper systematically analyzes the methods of determining the magnitude formula of single station and station network, the standard deviation of magnitude and the correction value of stations based on the Lg-Poire phase and non-Erie phase attenuation coefficients. According to the determination results of Lg attenuation coefficient of about 1 second in the areas of Jiangsu, Shandong, Henan, Anhui, Hebei and Zhejiang provinces in eastern China, the Lg magnitude formula of six provinces is derived: (?) (?) 19 Earthquake magnitude values, as well as 80 stations Taiwan school value. The standard deviation of single magnitude is 0.15-016 magnitude unit, and the standard deviation of magnitude of station network is 0.03-0.04 magnitude unit. In addition, the m_ (mxz) and m_ (mxh) values of 111 earthquakes were also determined, validating or supplementing some of the 19 earthquakes and their results.
