基于2004-2019年中国内地280个地级市面板数据,运用引力模型测度创新要素流动与数据要素流动环境指数,采用SBM-Undesirable模型测算城市绿色创新发展效率,使用空间杜宾模型分析创新要素流动对城市绿色创新发展的空间影响,并探究数据要素流动环境的空间调节效应。研究发现:创新要素流动仅通过改善绿色技术效率促进本地绿色创新发展,而对邻近地区绿色创新发展起抑制作用。在数据要素流动环境的调节作用下,从本地效应看,人才要素流动通过影响绿色技术效率和绿色技术进步促进城市绿色创新发展,呈“双轨驱动”特征;资本要素流动仅通过改善绿色技术效率提升城市绿色创新发展水平,呈“单轨驱动”特征。从空间溢出效应看,数据要素流动环境能合理调节人才和资本要素的空间流动,缓解创新要素的空间错配,进而对邻近地区绿色创新发展存在正向空间溢出效应。

In this paper,we propose a finite volume Hermite weighted essentially non-oscillatory(HWENO)method based on the dimension by dimension framework to solve hyperbolic conservation laws.It can maintain the high accuracy in the smooth region and obtain the high resolution solution when the discontinuity appears,and it is compact which will be good for giving the numerical boundary conditions.Furthermore,it avoids complicated least square procedure when we implement the genuine two dimensional(2D)finite volume HWENO reconstruction,and it can be regarded as a generalization of the one dimensional(1D)HWENO method.Extensive numerical tests are performed to verify the high resolution and high accuracy of the scheme.

沈从文在20世纪30年代两次返乡,写下三部经典的散文集《湘行书简》《湘行散记》和《湘西》,以亲身体验,向世人揭开了湘西的神秘面纱。虽然这三部散文集的描写对象同为湘西,但作家对这一神秘领地的文学书写,却表现出迥然不同的艺术风貌。《湘行书简》以游记体式和绘画笔法,客观描摹了一幅五彩斑斓的湘西风景画;《湘行散记》将地理感知转化为地理记忆,加入地理想象,通过筛选、加工和重组,再现了一部关于湘西人事的活历史;《湘西》则将地方志手法巧妙融入散文创作,较为科学地还原了湘西本相。三者艺术风貌的不同,显示出沈从文对故土湘西的地理感知由“现场体验”到“想象重组”再到“知觉审美”的进阶之旅。

In this paper, the sixth-order oscillation-free Hermite weighted essentially non-oscillatory (OFHWENO) scheme is proposed for hyperbolic conservation laws on structured meshes, where the zeroth- andfirst-order moments are the variables for the governing equations. The main difference from other HWENOschemes existing in the literature is that we add high-order numerical damping terms in the first-order momentequations to control spurious oscillations for the OF-HWENO scheme. The OF-HWENO scheme not only canachieve the designed optimal numerical order, but also can be easily implemented as we use only one set ofstencils in the reconstruction procedure and the same reconstructed polynomials are applied for the zeroth- andfirst-order moment equations. In order to obtain the adaptive order resolution when facing discontinuities, atransition polynomial is added in the reconstruction, where the associated linear weights can also be any positivenumbers as long as their summation equals one. In addition, the OF-HWENO scheme still keeps compactnessas only immediate neighbor values are needed in the space discretization. Some benchmark numerical tests areperformed to illustrate the high-order accuracy, high resolution and robustness of the proposed scheme.

Self-healing represents a next-generation technology in response to the common demands of polymeric materials for long-term stability and durability.It mimics the capability of naturally occurring species like living organisms to autonomously recover nonfatal harm.The damages inevitably generated during fabrication and service are allowed to be unconsciously repaired on a microscopic scale,and would no longer develop into macroscopic failures like the case of conventional materials.

For media with inclusions(e.g.,precipitates,voids,reinforcements,and others),the difference in lattice parameter and the elastic modulus between the matrix and inclusions cause stress concentration at the interfaces.These stress fields depend on the inclusions’size,shape,and distribution and will respond instantly to the evolving microstructure.This study develops a phase-field model concerningmodulus heterogeneity.The effect of modulus heterogeneity on the growth process and equilibrium state of theαplate in Ti-6Al-4V during precipitation is evaluated.Theαprecipitate exhibits strong anisotropy in shape upon cooling due to the interplay of the elastic strain and interfacial energy.The calculated orientation of the habit plane using the homogeneous modulus ofαphase shows the smallest deviation fromthat of the habit plane observed in the experiment,compared to the case where the homogeneous modulus ofβphase is adopted.In addition,the equilibrium volume ofαphase within the systemusing homogeneousβmodulus exhibits the largest dependency on the applied stresses.The stress fields across theα/βinterface are further calculated under the assumption of modulus heterogeneity and compared to those using homogeneous modulus of eitherαorβphase.This study provides an essential theoretical basis for developing mechanics models concerning systems with heterogeneous structures.
