Metallurgical behaviours on interface in explosive welding of combined plate;

By carrying out anti-seepage concrete construction craft in the earth rock dam,this article showed the construction process in the Danjiangkou reservoir dam for strengthening the quality monitoring and typical reclamation interface aspects,and stated some good construction measures for anti-seepage body s construction.

Based on the study of velocity distribution at mixing interface of turbidity current,an improved formula for calculating the water flow velocity distribution in the region higher than the maximum velocity and the turbidity flow velocity in the region beneath the maximum velocity is proposed.

To more accurately solve axisymmetric fluid flows with interfaces,Youngs method for axisymmetric coordinate systems is developed.
