Superconvergence of a Nonconforming Finite Element Approximation to Viscoelasticity Type Equations on Anisotropic Meshes

引用

Numerical Mathematics A Journal of Chinese Universities(English Series) 2006年第4期15卷 375-384页

作者： Dongyang shi Yucheng peng Shaochun chen Department of Mathematics Zhengzhou University Zhengzhou 450052 China

The main aim of this paper is to study the approximation to viscoelasticity type equations with a Crouzeix-Raviart type nonconforming finite element on the anisotropic meshes. The superclose property of the exact solution and the optimal error estimate of its derivative with respect to time are derived by using some novel techniques. Moreover, employing a postprocessing technique, the global superconvergence property for the discretization error of the postprocessed discrete solution to the solution itself is studied.

Three dithiooxalato (Dto) bridging one-dimensional Mn(Ⅱ) complexes [Mn(L)Dto](L = Phen (1), Bpy (2) and en (3)) were synthesized. All of the complexes have the similar one-dimensional structure through Dto bridge. The measurement of the variable temperature magnetic susceptibility of complex 1 showed that there are weak antiferromag- netic interactions between the Mn(Ⅱ) ions.

在页岩气勘探开发过程中,准确界定目的层中高产层段,对页岩气的效益开发具有十分重要的意义。为此针对四川盆地威远页岩气示范区高产层难以判定、导致水平井产气量差异巨大的问题,建立了水平井高产层段测井判识方法。首先以导眼井中游离气含气饱和度计算为基础,确定游离气富集的高含气饱和度层段,再以导眼井标志层测井组合特征建立小层划分标准,根据钻井旋回的连续性及沉积地层不可逆性原则,创建了"极值方波旋回对比"小层对比方法,准确界定了各水平井钻遇的地质小层。并利用同一井组各水平井钻遇不同小层厚度、实际压裂级数与产气量相关分析方法进行了方法验证。在此基础上对威远地区页岩气高产层段进行了判识,明确指出威远地区页岩气高产层段是下志留统龙马溪组底部的1套中高伽马值(超低去铀伽马)硅质页岩段,其厚度介于1.5~6.0 m,页岩气赋存方式以游离态为主。相关研究成果对该区块页岩气中高产层段的准确判识、界定并及时掌握其分布规律提供了技术支撑。

采用蛋白和脂肪水平双因素实验，通过检测云纹石斑鱼血清、肝脏和肌肉中免疫与抗氧化指标，为饲料蛋白和脂肪的适宜配比提供依据。以鱼粉和豆粕作蛋白源，鱼油和大豆油混合油作脂肪源，3个蛋白水平分别为：35％、40％、45％，每个蛋白水平分别设3个脂肪水平：9％、12％、15％，每组3个重复。LZM活力和IgM含量在蛋白水平40％～45％时较高，也呈现随脂肪水平增加而上升的趋势，且蛋白水平比脂肪水平和交互作用对LZM和IgM有更显著的影响。肝脏SOD活力在40％蛋白水平时较高，在低蛋白水平（35％）时SOD活力随脂肪水平上升而增强，而高蛋白水平（45％）时则相反。蛋白、脂肪水平和交互作用对CAT活力均有显著影响，蛋白水平较高CAT活力较强。肌肉SOD和CAT活力变化趋势与肝脏大致相反。MDA含量随蛋白水平增加而减小，蛋白水平对肝脏和肌肉MDA都有显著作用，随着饲料脂肪水平增加肝脏MDA显著下降。实验表明，饲料中蛋白质含量维持在一定水平（40％左右）是必要的，当蛋白需求满足时，适当增加脂肪水平有利于鱼体健康。
