 作者：... Tianbo Yang , Bo Song , Long Lin 来源：[J].Journal of Superconductivity and Novel Magnetism(IF 0.702), 2017, Vol.30 (6), pp.1545-1549Springer 摘要：First-principle calculations were performed to investigate the electronic structures and magnetic properties of Cr-doped LiZnAs. The Cr-doped LiZnAs system with Cr concentration of 6.25 % should be nonmagnetic, while the system favors spin-polarized ground states with Cr-dop...

 作者：Long Lin , Ji-En Deng , Chao-Ping Chen 来源：[J].Journal of Inequalities and Applications(IF 0.822), 2014, Vol.2014 (1), pp.1-14Springer 摘要：Abstract(#br)We present the asymptotic expansions of functions involving the ratio of gamma functions and provide formulas for determining the coefficients of the asymptotic expansions. As consequences, we obtain the asymptotic expansions of the Wallis sequence. Also, we establis...
