【摘要】 为拓宽台网的动态范围，根据山西大同遥测台网低倍率系统的建设及使用情况，简述了大同遥测台网提高定位精度、建立低倍率系统的方法及取得的实际效益，认为低倍系统可以解决大震记录限幅带来的震相识别困难问题，可提高定位精度。更多还原

【Abstract】 Based on the situation of the low multiple system construction and its use of Datong remote network,the implement method and benefaction of the low multiple system construction for developing dynamic range,improving location accuracy have been recounted briefly.It is suggested that the low multiple system can resolve the difficulties of the phase discrimination from the limited variation of the large earthquake records, and improve the location accuracy.更多还原
