地震分析尺的研制系国家地震局合同制项目。1988年年底,国家地震局派专家组对样尺进行了技术鉴定。鉴定委员会对该尺的评价是:该尺具有一尺多用的特点,可以测量钟差、到时和振幅,计算震中距、震源深度和震级。其设计精巧,可容纳走时表和量规函数等,理论依据科学合理。由于采用游标尺等技术,可提高量片分辨度,并应用列线图原理,替代量片,由各震相到时的相互关系相互判断或检验震相,为震源精确定位提供可靠依据。
Seismic analysis of the development of the Department of the National Seismological Bureau contract system project. By the end of 1988, the State Seismological Bureau sent an expert group to carry out technical appraisal on the ruler. Appraisal Committee of the assessment of the ruler is: The ruler with a foot multi-purpose features, can measure the clock, time and amplitude, epicenter distance, source depth and magnitude. Its sophisticated design, can accommodate the timetable and gauge functions, the theoretical basis of scientific and rational. Due to the adoption of such techniques as vernier scale, the resolution of the measuring slice can be improved and the column diagram principle can be used instead of the measuring slice to judge each other or check the seismic phase from the correlation between the phases, providing a reliable basis for accurate positioning of the seismic source.
