Three-dimensional model was built for second regression calculation to reveal the shrinkage process of body,the best equation obtained was y=A+Bx+Cx2,The calculation was compared with experimental results.
The multivariate linear equation of the heavy metals with PH(X_(?H)), Eh(X_(Eh)),Cl(X_(?) ),dissoved oxygeo(X_(DO))and chemical oxygen demand (X_(COD))Was established by multivariated regression calculation.
According to the analysis and regressive calculation conducted on blasting monitoring data, it is proposed that the blasting construction should be executed combining with blasting monitoring, and it is feasible and necessary to adjust the blasting scheme in time according to the monitoring data.
It is shown by the regression computation that in the area observed correlation coefficient between gross-β and the chlorinity is 0.916. Their regression equation isB=1.18 +0.075Cl. The water of Changjiang River dilutes seawater in the gross-β concentration.
Through regression computation using the measured manometer data of the left auxiliary dam in Fenhe Reservoir, the seepage elements under high water level conditions are obtained, and the seepage situation of the left auxiliary dam under high water level conditions are analyzed.
