摘要
对地下水位数字记录仪与模拟记录仪产出的水位资料进行了对比分析。结果表明,两者日均值相关系数在0.3956～0.9997之间,整时值相关系数在0.0526～0.9997之间;自流井水位资料的同步性较差;总体分析数字化水位仪观测精度优于模拟水位仪。
the digital data and analogue data of groundwater level are analysed by comparison.The results show that their correlation coefficient is from 0.3956 to 0.9997.The synchronism for data of artesian well is relatively weak.Generally speaking,digital observation is better than analogue observation in accuracy.
