| 摘 要： | 研究的区域为内蒙古中西部地区(38°～43°N,104°～116°E)。通过对数字地震观测技术系统(简称"数字系统")、模拟地震观测技术系统(简称"模拟系统")同步观测记录的对比,可以看到,数字系统在判断震相初动方面有着明显的优势;检测地震的能力明显高于模拟系统;在测定地震发震时刻、震中位置等方面,与模拟系统存在一些偏差,但差异并不很大,因此数字系统目录与模拟系统目录能够基本衔接。

| Abstract: | the region studied in the paper is west and middle areas of Inner Mongolia. The comparison of digital and analog observational systems shows that digital system has obvious advantage in the determination of initial phase, there are some deviations in origin time and epicenter position with analog system, but not large, so digital catalogue can basically be connected with analog catalogue. |

| Keywords: | digital system analog system seismic phase ability of detecting earthquake comparative analysis |
