摘要
分析了四川、云南的部分地倾斜数字化观测与模拟观测资料的特性 ,从频率范围、周期 10天以上的FFT谱特性、固体潮波振幅、相位特征值等方面 ,论述了地倾斜数字化资料较模拟记录资料的信息组成变化 ,并对资料的分析与应用进行了初步探讨。
Through the analysis of the digital and analogic observations at the stations in Sichuan and Yunnan provinces and in respects of frequency range,FFT spectral characteristic whose cycle more than 10 days,solid tide wave amplitude and phase characteristic value this paper discusses the variation of the information components of the data by digital observation compared with those by analogic observation and inquires into the analysis and application of these data preliminarily.
