| 4 | On the Complex Difference Equation of Hypergeometric Type on Non-uniform Lattices显示文摘In this article,we obtain a new fundamental theorems for Nikiforov-Uvarov-Suslov complex difference equation of hypergeometric type by the method of Euler integral transformation,its expression is different from Suslov’s Theorem.We also establish the adjoint equation for Nikiforov-Uvarov-Suslov difference equation of hypergeometric type on non-uniform lattices,and prove it to be a difference equation of hypergeometric type on non-uniform lattices as well.The particular solutions of the adjoint equation are then obtained.As an appliction of these particular solutions,we use them to obtain the particular solutions for the original difference equation of hypergeometric type on non-uniform lattices and other important results. | Jin Fa CHENG | 2020 | Acta Mathematica Sinica,English Series2020，36，5： | 2 |
| 5 | Stability Characterizations of ε-isometries on Certain Banach Spaces显示文摘Suppose that X, Y are two real Banach Spaces. We know that for a standard ε-isometry f : X → Y, the weak stability formula holds and by applying the formula we can induce a closed subspace N of *. In this paper, by using again the weak stability formula, we further show a sufficient and necessary condition for a standard ε-isometry to be stable in assuming that N is w*-closed in Y*.Making use of this result, we improve several known results including Figiel’s theorem in reflexive spaces.We also prove that if, in addition, the space Y is quasi-reflexive and hereditarily indecomposable, then L(f)≡span[f(X)] contains a complemented linear isometric copy of X;Moreover, if X =Y, then for every e-isometry f: X → X, there exists a surjective linear isometry S:X → X such that f-S is uniformly bounded by 2ε on X. | Li Xin CHENG Long Fa SUN | 2019 | Acta Mathematica Sinica,English Series2019，35，1： | 2 |
| 6 | Optimizing Heavy-duty Anticorrosive Performances of Coating Films Formed by Acrylate-vinylidene Chloride Copolymer Latexes through Twice-painting Technique显示文摘Twice-painting technique was adopted to prepare heavy-duty anticorrosive coating films formed by aqueous latexes of copolymers of vinylidene chloride(VDC) with an acrylate, namely methyl acrylate(MA), ethyl acrylate(EA), butyl acrylate(BA) or 2-ethylhexyl acrylate(EHA). Harsh salt-spray corrosion tests demonstrated that the optimized twicepainting technique was that the acidic latex solution was adjusted to p H 5-6 for the first painting, while it was utilized directly for the second painting. The test of 600 h of harsh salt-spray corrosion showed that MA-VDC85 coating could protect the steel excellently, whereas the other acrylate-VDC coatings with 75%-90% VDC content could not protect the steel so effectively. Further corrosion test showed that(1) MA-VDC85 coating protected steel from loss of metallic luster for at least 1000 h of salt-spray corrosion;(2) adhesion of MA-VDC85 coating to steel was excellent for at least 800 h of saltspray corrosion, but became very poor after 1000 h. Differential scanning calorimetry, thermogravimetric analysis, X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy were used to evaluate the corroded MA-VDC85 film. | Ce Fu Tong-xian Zhang Cheng-qi Ji Fa Cheng Wen-zhu Cui 陈宇 | 2015 | Chinese Journal of Polymer Science2015，33，1： | 2 |
