| 摘要: |
| 为了解WCZ-3S陆地地磁日变观测系统的性能，分别在江苏盐城和海南三亚将WCZ-3S与Sentinel基站磁力仪、WCZ-2磁力仪、WCZ-3磁力仪进行了同步测量，通过比较分析的方法，对WCZ-3S的测量精度、测量曲线的准确性、磁暴识别功能进行了检验。测试结果表明：WCZ-3S的实测精度约为0.3 nT，稍逊于Sentinel基站磁力仪；WCZ-3S与其他几台磁力仪所测曲线的幅值、相位保持一致；WCZ-3S的实时成像功能可帮助台站工作人员对海洋磁力测量期间的磁暴现象进行识别。 |

| Abstract: |
| To understand the performance of the WCZ-3S terrestrial geomagnetic diurnal variation observation system, a comparison study was made synchronously between WCZ-3S and Sentinel, WCZ-2 and WCZ-3 magnetometers in Yancheng, Jiangsu, and Sanya, Hainan, respectively. The measurement accuracy, measurement curve, and magnetic storm identification capability of WCZ-3S were tested. The results showed that the measurement accuracy of WCZ-3S was about 0.3 nT, which was slightly inferior to that of Sentinel. Moreover, it was consistent with the amplitude and phase of the curves measured by other magnetometers. Using the real-time imaging function of WCZ-3S, the station staff successfully identified the magnetic storm phenomenon during the marine magnetic survey. |
