An error in closure stress measurement can lead to a significant error in the estimation of the net pressure and, consequently, the fracture geometry.
闭合应力测量的错误会对净压估计，以及随后的断裂几何形状的估计造成严重的错误。

We suggest "error of closure" asa criterion of measuring accuracy and use transient root-mean-square error to ex-press repeatability and reliability of measurement of the instrument.
Many altered rocks in hydrothermal deposit have multiple precursors. The lithogeochemical heterogeneity in rocks are mainly due to measurement error, closure and petrological controls.
