The Singular Value Decomposition for Generalized Radon Transforms |in R^n
R^n上广义Radon变换的奇异值分解

WANG Jin-Ping,
王金平

数学物理学报(A辑) , 2004,
Abstract: The singular value decompositions for the generalized Radon transforms are constructed when they are restricted to function spaces which are square integrable on R+n with known weight function W-n, some results about inverse transforms of the generalized Radon transforms are given. Furthermore, the inversion formulae and characteristics of their ranges are also developed.
Strong Convergence of a New Iteration for a Finite Family of Accretive Operators
Hu Liang-Gen,Wang Jin-Ping
Fixed Point Theory and Applications , 2009,
Abstract: The viscosity approximation methods are employed to establish strong convergence of the modified Mann iteration scheme to a common zero of a finite family of accretive operators on a strictly convex Banach space with uniformly Gateaux differentiable norm. Our work improves and extends various results existing in the current literature.

Green and Sustainable Chemistry (GSC) , 2011, DOI: 10.4236/gsc.2011.13011
Abstract: An eco-friendly synthesis of cyclododecanone (CDON) from cyclododecatriene (CDT) is described. Selec- tive epoxidation of CDT with hydrogen peroxide using hexadecyl trimethyl ammonium heteropolyphospha- totungstate [(n-C16H33NMe3)3PW4O16, HAHPT] as catalyst and water as solvent followed by the hydrogena- tion on Raney nickel catalyst gave cyclododecanol (CDOL). The latter was oxidized with hydrogen peroxide using HAHPT as catalyst and a mixture of water and t-butanol as solvent to afford CDON. The total yield was 53.4% under the optimum reaction conditions.
Features of interdecadal changes of the East Asian summer monsoon and similarity and discrepancy in ERA-40 and NCEP/NCAR Reanalysis
东亚夏季风年代际变化的若干重要特征及两份大气再分析资料的异同

HAN Jin-Ping,WANG Hui-Jun,
韩晋平

地球物理学报 , 2007,
Abstract: 本文利用ERA和NCEP/NCAR再分析资料,以及部分观测资料,研究了东亚夏季风年代际变化的若干重要特征.结果表明,东亚夏季风在20世纪70年代末减弱这一现象是普遍存在的,主要表现为江淮地区表面温度降低,海平面气压升高,出现偏北风异常.研究发现,这次年代际变化还体现在与东亚季风环流密切相关的重要环流因子,如西太平洋副热带高压、欧亚西风、澳大利亚高压、南极涛动等,它们在20世纪70年代末以后都进入高指数时期.此外,文章还揭示:ERA和NCEP/NCAR再分析资料在东亚夏季风年代际变化上基本吻合,但也有很多差别.

catena-Poly[[(1,10-phenanthroline-κ2N,N′)lanthanum(III)]-μ-(5-bromo-2-hydroxybenzoato)-κ2O1:O1′-di-μ-chlorido]
Wen-Qing Zhu,Jin-Ping Wang,Yu-Kun Yuan,Zhuo Li
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812025500
Abstract: In the title complex, [La(C7H4BrO3)Cl2(C12H8N2)]n, the LaIII ion is eight-coordinated by two carboxylate O atoms from two 5-bromosalicylate ligands, two N atoms from a chelating 1,10-phenanthroline ligand and four bridging Cl atoms in a distorted square-antiprismatic geometry. The LaIII ions are linked by bridging carboxylate groups and chloride anions into a chain along [100]. An intramolecular O—H...O hydrogen bond is formed in the 5-bromosalicylate ligand. π–π interactions between the pyridine and benzene rings and between the benzene rings are observed [centroid–centroid distances = 3.794 (5) and 3.804 (4) ].

Abstract: 摘要: 利用分数次积分交换子和Riesz位势在变指标Lebesgue空间有界的结果,基于变指标Herz-Hardy空间上的原子分解理论,以及Lipschitz函数的特征和经典的不等式估计,证明了分数次积分交换子是从变指标Herz-Hardy空间到变指标Herz空间的有界性。
Abstract: By the boundedness of commutators for fractional integrals with Lipschitz functions and the Riesz potential on variable Lebesgue spaces, based on the atomic decomposition of Herz-type Hardy spaces with variable exponents, using the properties of Lipschitz functions and the estimations of the classical inequalities, we proved that the Lipschitz commutators of fractional integrals are bounded from Herz-type Hardy spaces with variable exponents to variable Herz spaces
