1Influence of NaCl Deposition on Atmospheric Corrosion of A3 Steel显示文摘Regularity of the initial atmospheric corrosion of A3 steel in the presence of NaCl was investigated.The results showed that NaCl can accelerate the corrosion of A3 steel.Dry mass gain of A3 steel in the presence of NaCl deposition increases with the exposure time,which can be correlated by using exponential decay function.The relationship between dry mass gain and amount of NaCl deposition at a certain exposure time follows a quadratic function.More amount of NaCl deposition will slow down the corrosion rate to some extent after exposure for a certain time .SEM/EDAX was used to characterize the corrosion surface and products.The surfaces of the NaCl treated A3 steel were obviously uneven, and some tiny crevices appear in the corrosion products that could help O2 transmit to the inner layer.The amount of oxygen in atomic percentage in the corrosion products increases with the amount of NaCl deposition.QingQU ChuanweiYAN2002Journal of Materials Science & Technology2002,18,6:3

5Efficient numerical algorithms for the phase field crystal equation显示文摘In this paper,based on the Lagrange Multiplier approach in time and the Fourierspectral scheme for space,we propose efficient numerical algorithms to solve the phase field crystal equation.The numerical schemes are unconditionally energy stable based on the original energy and do not need the lower bound hypothesis of the nonlinear free energy potential.The unconditional energy stability of the three semi-discrete schemes is proven.Several numerical simulations in 2D and 3D are demonstrated to verify the accuracy and efficiency of our proposed schemes.Qingqu Zhuang Shuying Zhai Zhifeng Weng 2021International Journal of Modeling, Simulation, and Scientific Computing2021,12,5:0
6A Spectral Element/Laguerre Coupled Method to the Elliptic Helmholtz Problem on the Half Line显示文摘A Legendre spectral element/Laguerre coupled method is proposed to numerically solve the elliptic Helmholtz problem on the half line. Rigorous analysis is carried out to establish the convergence of the method. Several numerical examples are provided to confirm the theoretical results. The advantage of this method is demonstrated by a numerical comparison with the pure Laguerre method.Qingqu Zhuang Chuanju Xu 2006Numerical Mathematics A Journal of Chinese Universities(English Series)2006,15,3:0
