南昌地震台数字水位与模拟水位观测对比研究

Research on the comparison between the digital record and the analogue record of water level at Nanchang Seismographic Station

对南昌台数字水位与模拟水位的观测资料进行了对比研究,发现它们的动态变化是一致的,数据的相关性良好,虽然数字水位在记录连续水震波方面逊于模拟水位,但综合分析,数字化仪器的信息量大、快捷,优于模拟水位,完全可以取代模拟水位。

The paper has made some comparative researches between the digital record and the analogue record of water level at Nanchang Seismographic Station. The result indicates that their dynamic variations are accordant with each other, and the correlation between them is very good. Although the digital record is inferior to the analogue record in recording continuous water wave, the former is better than the latter in comprehensive analysis for water level, and the former can substitute for the latter completely.
