COMPARISON AND RESEARCH ON DIGITAL AND ANALOGUE SUBSURFACE FLUID DATA

The digital and analogue subsurface fluid data in Hebei Province is compared in the field of instrument capability, continuity and correlation of data and their inherent quality.The results show that the continuity of analogue data is better than digital data.The correlation of water level data is better, for the majority of observations can pass the test of variance consistency and water level of three wells passed the test of mean value consistency.The correlation of radon and mercury is not good, because neither of their variance and mean consistency passed test.
