| 摘 要： | 选取了河北及邻区58个不同区域的地震,分析“定位子台网”分布对地震定位精度的影响,研究“定位子台网”的选取规则。分别探讨了三种台站分布情况下定位偏差、水平误差、拟合残差随空隙角、近台距离、远台距离的变化;定位偏差以及水平误差与拟合残差的关系。结果显示,速报时选择7~9个分布相对合理的“定位子台网”参加定位结果比较好,使用水平误差估计定位结果质量比较适合。 |
| 关 键 词： | 定位子台网 台站分布 定位偏差 水平误差 拟合残差 |

| Abstract: | Selecting 58 earthquakes occurred in Hebei Province and adjacent regions,rules of subarray selection are studied based on analyzing the influence of station distributions on the accuracy of locating result.The locating deviation,horizontal error,fitting residual with clearance angle,variation with near station and far station,and relation of locating deviation with horizontal error and fitting residual were discussed separately.The results show that it is suitable to select 7 to 9 stations for earthquake locating in rapid report.It is relatively suitable to evaluate the quality of the locating result with horizontal error. |
| Keywords: | Locating subarray Station distribution Locating deviation Horizontal error Fitting residual |
