When the system is confined well, the change of observation water level has a linear relation with water head change.

在系统封闭很好的情况下，观测水位的变化基本与水头的变化呈线性关系。

In water level, analog observation and digital observation are difference in nature. Two kinds of data are consistent in trend and natural quality but different in stability and accuracy.

而水位的数字化与模拟观测，因其观测的原理存在差异，虽然二者的趋势变化一致、内在质量相当，但其精度和稳定性却存在较大差异。
