摘　　要：本文通过对辽宁数字地震台网控制区内近11年的地震观测数据进行处理分析,应用最小二乘法求回归方程等一系列相关公式进行计算,最终依据辽宁地区近震走时与震中距之间关系,归纳成表。为编制辽宁地区近震走时表提供可靠的数据依据。Based on the analysis of the seismic data observed in Liaoning digital seismic network controlling region in the recent 11 years, and the calculation of the least square method and other related methods, the relationship between the travel time and the epicenter distance are concluded. It provided data basis for the compilation of local earthquakes＇ travel time in Liaoning area.
