    493-500页
    查看更多>>摘要：Let Γd2n be the set of trees with a given diameter d having a perfect matching,where 2n is the number of vertex.For a tree T in Γd2n,let Pd+1 be a diameter of T and q =d - m,where m is the number of the edges of perfect matching in Pd+1.It can be found that the trees with minimal energy in Γd2n for four cases q =d - 2,d - 3,d - 4,[d/2],and two remarks are given about the trees with minimal energy in Γd2n for (2d-3)/3 ≤ q ≤ d - 5 and [d/2] + 1 ≤ q ≤ (2d-3)/3 - 1.

    Global existence and blow-up of solutions to reaction-diffusion system with a weighted nonlocal source

    501-505页
    查看更多>>摘要：In this paper,we study a semi-linear reaction-diffusion system with a weighted nonlocal source,subject to the null Dirichlet boundary condition.Under certain conditions,we prove that the classical solution exists globally and blows up in finite time respectively,and then obtain the uniform blow-up rate in the interior.

    Simulation of two-phase flows of a droplet impacting on a liquid film with an improved lattice Boltzmann model

    ZHANG Chong-mingWANG Xiao-yongGUO Jia-hong
    506-509页
    查看更多>>摘要：Based on the lattice Boltzmann method (LBM),an improved pseudo-potential model,combined with a method of adding force term,is used to simulate the two-phase flows caused by a liquid droplet impacting on a liquid film.In this model,the different phases are treated as one fluid,and the interfaces between the vapor and liquid phases can be obtained by density value of the fluid.This variant of the LBM allows one to obtain the densities of vapor and liquid with high accuracy.The model is validated by an example of phase separation.The early stage of the impact of droplet on liquid film is simulated,and the results are qualitatively consistent with physical phenomena.

    Oscillation theorems for second-order nonlinear perturbed differential equations with damping

    ZHANG MengSONG Guo-hua
    510-516页
    查看更多>>摘要：A class of second-order nonlinear damped perturbed differential equations is considered and its oscillation theorems are studied.These theorems are more general and deal with the cases which are not covered by the known criteria.Particularly,these criteria extend and unify some existing results.An example is given to verify the results.

    Generating functions for powers of second-order recurrence sequences

    WANG Xiao-xiaLI Mei
    517-521页
    查看更多>>摘要：For the sequences satisfying the recurrence relation of the second order,the generating functions for the products of the powers of these sequences are established.This study was from Carlita and Riordan who began a study on closed form of generating functions for powers of second-order recurrence sequences.This investigation was completed by Stǎnicǎ.Inspired by the recent work of István about the non-closed generating functions of the products of the powers of the second-order sequences,the authors give several extensions of István's results in this paper.

    Decomposition analysis of carbon reduction measures and carbon emission changes in five areas in China

    JIANG ShuWAN HaoSHAO ShenYUAN Yi...
    522-528页
    查看更多>>摘要：Based on the analysis of primary energy consumption structure in five main provinces or municipalities in China,the factors that affect carbon emissions in the five study areas are analyzed quantitatively and comparatively with the decomposition analysis method.Empirical results demonstrate that the decomposition models of carbon emissions can be defined as "municipality model" and "provincial model",and the population factor of "municipal model" plays a significant role in carbon emissions than that of "provincial model".Either positive or negative effects of energy structure can be found in five different areas.However,there is a general trend that energy structure effort is becoming more and more important.Based on the characteristics and trends of carbon emissions in different areas,the carbon reduction measures are proposed as well.

    Spin-orbit coupling modification of photons to ray equation in inhomogeneous medium

    ZHONG FangJI Pei-yong
    529-534页
    查看更多>>摘要：Based on the principle of general relativity,geometrization of interaction,the interaction of the inhomogeneous isotropic medium to light can be equated to a non-Euclidean geometry field just like the situation of gravity,i.e.,light travels in the null geodesic in the non-Euclidean curved space-time,which is equivalent to the Fermat principle for the inhomogeneous media.In this paper,the propagation of light in an inhomogeneous media is studied by means of the effective metric theory.The modification to the classical ray equation of photons is derived from the geodesic equation of photon by considering the spin effect of photons,which is induced via the spin-orbit coupling of photons,and the corresponding Hamiltonian of photon is proposed.Based on the spin-orbit coupling of photon,a light splitting phenomenon emerges in the inhomogeneous media,which is the spin hall effect of photon.

    Effects of La3+ on microwave dielectric properties of (Pb0.5Ca0.5) (Fe0.5Ta0.5)O3 ceramics

    JIANG Yong-changGU YingYANG Qiu-hongKIM Eung-soo...
    535-537页
    查看更多>>摘要：This work investigated the microwave dielectric properties of A-site substitution by rare earth La3+ in (Pb0.5Ca0.5)(Fe0.5Ta0.5)O3 (PCFT) system.A single perovskite phase was obtained only when the doping content was 2％.Suitable La3+ doping improved microwave dielectric performances.Excessive La3+ doping caused the formation of secondary phase,which resulted in the decreasing of permittivity εr and quality factor Qf values.Especially,when the doping content is 2％-5％,permittivity εr was above 75 and Qf values were 6 902-7 416 GHz.

    538-541页
    查看更多>>摘要：Silicon carbide nanotubes (SiCNTs) with special morphology synthesized by supercritical hydrothermal method at 470 ℃ and 8 MPa have been reported in this paper.SiCNTs with special morphology were characterized by transmission electron microscopy (TEM) and high-resolution TEM (HRTEM).There are two kinds of silicon carbide with special morphology:One is oval SiCNTs with small aspect ratio,the other is bamboo cone-shape structure.SiCNTs have been analyzed by fluorescence spectrometer.The results indicate that the SiCNTs have strong photoluminescence (PL) property.The SiCNTs with oval shape are one kind of intermediate state of growth process of nanotube.The growth mechanism of silicon nanotubes has been proposed based on experiment data.The investigations of growth mechanism of SiCNTs with bamboo structure show that the defect produced in the growth process play the important role in SiCNTs with special structure.

    Multivariate adaptive regression splines based simulation optimization using move-limit strategy

    MAO Hu-pingWU Yi-zhongCHEN Li-ping
    542-547页
    查看更多>>摘要：This paper makes an approach to the approximate optimum in structural design,which combines the global response surface (GRS) based multivariate adaptive regression splines (MARS) with Move-Limit strategy (MLS).MARS is an adaptive regression process,which fits in with the multidimensional problems.It adopts a modified recursive partitioning strategy to simplify high-dimensional problems into smaller highly accurate models.MLS for moving and resizing the search sub-regions is employed in the space of design variables.The quality of the approximation functions and the convergence history of the optimization process are reflected in MLS.The disadvantages of the conventional response surface method (RSM) have been avoided,specifically,highly nonlinear high-dimensional problems.The GRS/MARS with MLS is applied to a high-dimensional test function and an engineering problem to demonstrate its feasibility and convergence,and compared with quadratic response surface (QRS) models in terms of computational efficiency and accuracy.
