摘要

通过对台站观测资料评比标准变化的分析比较,认识到要提高测震观测资料的质量就要在震相分析、震级测定、单台报告和数据报送4个方面做好工作,就要注意地震初至波到时精度在地震观测质量中的重要性。管理人员要仔细调整观测仪器系统状态,核准本台台址的经纬度和高程参数,注意时间服务精度,使得仪器处于良好工作状态,同时提出改善地震初至波到时精度的几个建议。
Through the examination of the seismic data each year,the seismic routines to recognize seismic waves,determine earthquake magnitudes,report earthquake parameters and transfer the seismic data are very important in order to improve the work of seismic stations.The important factor is to read the arriving time of seismic waves more precisely among them.Besides,the operators should pay more attention to the state of the instrument operation and adjust the gauge parameters in order to obtain the good observation results.For example,the parameters such as the level,longitude,latitude of seismic stations and the service time used to locate the epicenter should be more precise.Some suggestions are put forward.
