On the basis of the thermal-elastic-plastic theory, a three-dimensional finite element numerical simulation is performed on the girth welded residual stresses o
A new complex [Cu(C12H8N2)2]1.5PW12O40·1.5H2O was synthesized under hydrothermal conditions. The complex was characterized by the elemental analysis, SEM, X-ra
In order to understand the change regulation of residual stress during multi-repaired welding to provide theoretical guidance for correct repaired welding proce
Ferrous chelate absorption is deemed a promising method for NO removal from flue gas, but the key problem is the difficulty to regenerate the absorption solutio
The glass sample based on the composition of 45PbF2-45GeO2-10WO3 co-doped with Yb3+/Er3+ was prepared by the fusion method in two steps: melted at 950 ℃ for 20
