"艺术终结"是20世纪美学的一个重要议题。通过对黑格尔和丹托的"艺术终结论"的分析,可以发现其理论并不能支持"艺术已经死亡"这个为大多数学者所理解的结论。"艺术终结"之后,艺术将继续存在,条件是必需存在于哲学解释的"理论氛围"之中。与此相应,哲学必须借助艺术来达到它自身的目的。艺术与哲学的结盟,是双方的共同要求。

A novel catalyst for the direct vapor phase carbonylation of methanol without the addition of any halide in the feed as a promoter is investigated. Compared to the known liquid phase methanol carbonylation process, the advantages of this vapor phase reaction are as follows: corrosive attack to reactors and pipes of iodide-acid solution may be avoided;the separation of the products from the catalyst is facilitated by a gas-solid system;the reaction is carried out under the moderately pressurized condition;and the catalyst is cheap. It is demonstrated that the mechanism of the direct vapor phase carbonylation of methanol is not similar to the mechanism in the homogeneous process catalyzed by Rh in the presence of an iodide promoter.

In this paper, we study the dynamics of a diffusive modified Leslie-Cower model with the multiplicative Allee effect and Ba^zykin functional response. We give detailed study on the stability of equilibria. Non-existence of non-constant positive steady state solutions are shown to identify the rage of parameters of spatial pattern formation. We also give the conditions of Turing instability and perform a series of numerical simulations and find that the model exhibits complex patterns.

Biology has been a brilliant teacher and a precious textbook to man-made construction for thousands of years, because it allows one to learn and be inspired by nature＇s remarkable and efficient structural systems. However, the emerging biomimetic studies have been of increasing interest for civil engineering design only in the past two decades. Bridge design is one of aspects on structural engineering of biomimeties that offers an enormous potential for inspiration in various aspects, such as the ge- ometry, structure, mechanism, energy use and the intelligence. Recently built bridges and design proposals in which biological systems have produced a range of inspiration are reviewed in this paper. Multidisciplinary cooperation is discussed for the implementation of bio-inspired methods in future design. A case study about using bio-inspired strategy is trying to present a problem-solving approach, yet further cooperation is still needed to utilize biomimetie studies for design inspiration. This paper aims to call a close multidisciplinary collaboration that promotes engineers to build more sustainable and smart structural systems for bridges in the 21 st century.

The structural and thermoelasticity of antifluorite magnesium silicide at high temper- atures were studied by using the plane-wave pseudo-potential method in the frame- work of density functional theory. The bulk ground-state quantities such as lattice constants, cell volumes, band structures and elastic constants were calculated. It showed that the elastic constants of Mg2Si were well consistent with the experimen- tal data under ambient conditions. The crystal cell volume and bulk modulus of Mg2Si as functions of applied temperature were also presented. The lattice dynamics was applied to determine the phonon dispersion curves. To complete the fundamental characterisation of this crystal, the coefficients of thermal expansion （CTE）, isochoric heat capacities and Debye temperature of Mg2Si in the whole temperature range from 0 K to 1300 K and pressure range from 0 GPa to 7.48 GPa were investigated. The results were in favourable agreement with the previous theoretical calculations and the existing experimental data.

A Cu–Fe–La/γ-Al_2O_3(CFLA) catalyst was prepared by the excessive impregnation method and characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The results indicate that the catalyst contained mostly Cu^(2+), Fe^(3+), and La^(3+)and a small amount of Cu^+, Fe^(2+), and La. The active components were uniformly distributed in the catalyst, and the particle size of the components was approximately 7.5 nm. The CFLA catalyst was used for the treatment of methyl orange(MO) solution by catalytic wet air oxidation(CWAO), and it exhibited a high catalytic activity. The catalytic reaction involved variable valence states of metals and free-radical reaction mechanism. The CWAO reaction of MO solution was fitted by a segmented first-order dynamic model, and the rapid reaction apparent activation energy was 13.9 k J·mol^(-1).

By measuring the temperature dependence of the magnetic susceptibility, two distinct transitions have been observed in potassium doped cobalt oxide KxCoO2 (x = 0.2-1.0). The transition around 125K corresponds to a phase transition between a weak ferromagnetic plus a strong superparamagnetic phase (below 125K) and a superparamagnetic phase (above 125K). The susceptibility above the Curie point Tc cannot be described by the Curie-Weise law, being consistent with the superparamagnetism. Magnetization-hysteresis-loops have been measured in different temperature regions to uncover the underlying physics. The second transition near 30.8K shows a strong novelty.
