本文第一部分对山东台网测定震级的状况进行了分析。(1)简单地阐述了山东台网的发展史和测定震级的概况。(2)对山东台网测定的震级与邻省台网测定的震级进行了比较,得出本区台网震级测定的比河北、河南、安徽台网大0.1-0.24,比江苏台网小0.06级。(3)初步分析了山东台网位于两种不同岩性的台站所测定的震级的差异,通过统计计算,位于岩性较好的台站测定的震级比位于黄土复盖较厚的台站测定的震级小0.1—0.7。本文第二部分针对山东台网位于两种不同岩性松散沉积层和岩性较好的台站,所测定的震级偏差较大的现象进行了研究。利用1977—1987年发生在本省以及邻省的近500余次 ML=1.8—4.8的地震资料。采用震级残差法,在原来量规函数 R_1(△)的基础上,得到了适用于本区两种不同岩性的区域性量规函数 R 鲁(△)岩和 R 鲁(△)沉。
The first part of this paper analyzes the status of the magnitude of Shandong station network. (1) Briefly expounded the history of Shandong station network and the general situation of magnitude determination. (2) The magnitude determined by Shandong station network is compared with the magnitude measured by neighboring station. The results show that the magnitude of this station’s station magnitude is 0.1-0.24 larger than that of Hebei, Henan and Anhui, 0.06 level. (3) A preliminary analysis of the differences in the magnitude of shale stations located at two stations of different lithology in Shandong Province is carried out. By means of statistical calculation, the magnitude at stations with better lithology is higher than those at stations with thick loess layers Determination of the magnitude of 0.1-0.7. The second part of this paper is aimed at the phenomenon that the Shandong station network is located in two kinds of loose sedimentary layers with different lithologies and stations with good lithology, and the measured magnitude deviation is large. Using nearly 500 ML = 1.8-4.8 seismic data from 1977 to 1987 in this province and its neighboring provinces. Based on the original R 1 (△) gauge function, we use the magnitude residual method to obtain the regional gauge functions Rlu (△) and Rlu (△) for two different lithologies in this area.
