从CD生产函数出发,分别从不同收入分配层次、税收体系与设计、税种设计与选择等方面来具体阐释税收在不同收入分配层次中的作用机理,以揭示税收体系设计与选择对改变收入分配格局的作用机理.研究证明,个人所得税对改变收入分配的格局具有直接的作用,消费税对改变收入分配的格局具有间接的作用.个人所得税和消费税税率的改变对个人消费一般性商品时所消耗的收入占总收入比重的影响是税收体系改变收入分配格局的关键.为使税收有效调节收入分配,税收体系设计应反映在收入分配各个环节;税种的设计与选择应体现在范围和力度上;税收调节收入分配应具有普遍性与特殊性.

This paper focuses on the university students' innovation and entrepreneurship education reform in our country. Innovation and entrepreneurship education in universities is of great significance for scientific and technological development. University students' innovation and entrepreneurship education is beneficial to facilitate education reform and to promote comprehensive quality of university students and ultimately to advance the overall development of university students. However, the innovation and entrepreneurship education of our country has many problems that mainly reflect in immature education idea, weak teachers group and old education content at present. Through deepening the concept of innovation and entrepreneurship education, strengthening the teachers group of innovation and entrepreneurship education, updating teaching content and other aspects, we could implement the reform of university students' innovation and entrepreneurship education.

The transient thermo-piezoelectric response of a functionally graded piezoelectric rod subjected to a moving heat source is investigated in the context of fractional order theory of thermoelasticity proposed by Sherief. The material properties of the functionally graded piezoelectric rod are assumed to vary exponentially along the length, except for the thermal relaxation time and the specific heat, which are taken to be constant. To solve the governing equations of the problem, Laplace transform is applied, eliminating the time effect; the analytical solutions of the displacement, stress, temperature, and electric field in Laplace domain are obtained. Subsequently, the solutions of the considered variables in time domain are obtained by numerical Laplace inversion and illustrated graphically. In calculation, the effect of the fractional order parameter on the variations of the considered variables is presented.

Ablation behavior of double-layer ZrB2-based ceramic coating for lightweight ZrB2 modified carbon bonded carbon fiber (CBCFs/ZrB2) composites was tested under an oxyacetylene flame at elevate temperature (1500, 1600 and 1700 degrees C) for 600s. The results indicate that the ablation temperature has significant effect on the microstructure and ablation behavior of the coated CBCFs/ZrB2 composites. The as-prepared coating could efficiently protect CBCFs/ZrB2 composites against oxidation from 1500 to 1700 degrees C for 600s. The ZrB2-based ceramic coating had a good self-healing ability at 1500 degrees C and 1600 degrees C. With the increasing ablation temperature to 1700 degrees C, the coating exhibited severe ablation. However, the molten SiO2 from the coating seeped into the CBCFs/ZrB2 composites forming a coating layer on the carbon fibers surface which acted as an efficacious oxidation protective barrier.

Buckling analysis is a technique used to determine buckling load and buckled mode shape. Buckling load is the critical load at which a structure becomes unstable while buckled mode shape is the characteristic shape associated with a structure's buckled response. In this paper, the elastic thermal buckling of a heated cyclic symmetry structure is carried out by means of finite element method. The buckling cyclic symmetry analysis is focused on a ring-strut-ring structure which is extensively used as a basic element in rotating machines. The linear eigenvalue buckling analysis is adopted to determine the buckling response with the temperature change of the structure.

The hyperelastic constants in the strain energy density function of a material determine its mechanical response. Therefore, in order to obtain successful results during a hyperelastic analysis, it is necessary to accurately assess the material constants of the materials being examined. Material constants are generally derived for a material using experimental stress-strain data. It is recommended that this test data be taken from several modes of deformation over a wide range of strain values. In fact, it has been observed that to achieve stability, the material constants should be fit using test data in at least as many deformation states as will be experienced in the analysis. The goal of hyperelastic material Structure Analysis is to find the best use of material for a body such that an objective criteria takes out a maximum/minimum value subject to given constraints.

随着"硅谷"的大获成功,科学园模式在世界各地被复制。但基于各国客观经济、社会条件的差异和对科学园建立、发展的主观理解不同,形形色色的科学园体现出了各种不同的运作模式。英国剑桥科学园和日本筑波科学园分别可视为大学主导模式和政府主导模式,通过对两种模式的利弊分析,我们认为这两种模式均存在自身的缺陷,而建立大学、政府和企业的平等关系,构建协同创新的科学园区,将是一种更好的选择。
