【摘要】 对洛阳地震台数字与模拟地震记录并行观测27个月的资料进行对比分析,认为:数字观测具有记录频带宽、获取的地震信息量更丰富、地震波到时的量取更准确等多方面的显著优势。数字记录的初至波早于模拟记录,且持续时间较长,大部分的数字地震震级比模拟记录、标准震级小。

【Abstract】 The comparative analysis of digital and analog seismic data, that simultaneously recorded at Luoyang Seismic Station for 27 months shows that the digital observation has remarkable advantages in many ways, such as wider frequency band, richer seismic information, and more accurate measure of the arriving time of seismic wave. The first array wave in digital record is earlier than that in analog record, and with longer duration. It also found that the most of the earthquake magnitudes determined by digital records are less than the criterion and that determined by analog records.
