摘要：
Bismuth Tungstate (Bi2WO6) that was prepared by solid-state reaction at high temperature in previous work showed catalytic activity in the degradation of organic compound under visible light Irradiation. During the past three years, some reports on the fabrication of Bi2WO6 nano-/microstructures in solution and their use as visible-light photocatalysts have emerged. Despite much progress In this exciting field, no report has discussed the repeating usage of this material to degrade organic compounds, partially due to the lack of well-defined Bi2WO6 structures. In this article, red-cell-like Bi2WO6 hierarchical architectures consisting of a number of square nanoplates of average similar to 30 nm in side length have been firstly synthesized by a hydrothermal method at 180 degrees C for 12 h. These as-prepared microstructures have biconcave configurations with typical sizes of 1.8-2.5 pro, uniform and monodisperse. TEM examination indicates that the single-crystal subunit nanoplates with (001) as their two-dimensional (2D) surfaces assemble orderly using both their edges and faces. The good photocatalytic activity in the degradation of rhodamine B under visible light irradiation (lambda > 400 nm) Is also discussed. Furthermore, we show that these architectures can serve as effective and convenient recyclable photocatalysts, which is crucial to Industrial applications. Only a slight decrease In the photodecomposition rate is observed after 5 cycles of the photocatalysis experiment. All these results demonstrate that the red-cell-like Bi2WO6 hierarchical architectures are promising visible-light-driven photocatalysts and have many potential applications in environmental protection.

In this paper, we will study the Cauchy problem for the generalized KdV-Burgers-Kuramoto equation, which represents a dissipative, stroboscopic and unstable system in physics. When the initial data is a small disturbance of a rarefaction wave of the inviscid Burgers equation, we prove the global existence of the solution to the corresponding Cauchy problem and asymptotic stability of the rarefaction wave. The analysis is based on a priori estimates and the L-2-energy method. (c) 2006 Elsevier Ltd. All rights reserved.
摘要：
This paper addresses the syntactic and semantic properties of ＂X ＋ deng（等） ＋ NP＂ as a listing structure and component parts. As a listing, ＂Deng（等） ＂ must appear in a listing structure. ＂Deng（等） ＂ includes three semantic degree： listing incompletely, listing uncertainly and listing completely. This is a process of functionalization, accompanying with the gradual entrancing of subjectivity. ＂X＂ has a variety of form and variable feature. Its components must be alike in detail-aspects of meaning. ＂NP＂ belongs to assemble noun and its appearing or disappearing is flexible in listing structures. ＂X ＋ deng（等） ＋ NP＂ can act as subject, object or attribute, and include two structure semantics ： ＂list＂, ＂big quantities＂. The research also shows that whole construction has some forms and semantics that components don＇t have.

摘要：
We present STAR results on the elliptic flow upsilon(2) Of charged hadrons, strange and multistrange particles from,root s(NN) = 200 GeV Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC). The detailed study of the centrality dependence of upsilon(2) over a broad transverse momentum range is presented. Comparisons of different analysis methods are made in order to estimate systematic uncertainties. To discuss the nonflow effect, we have performed the first analysis Of upsilon(2) with the Lee-Yang zero method for K-S(0) and A. In the relatively low PT region, P-T <= 2 GeV/c, a scaling with m(T) - m is observed for identified hadrons in each centrality bin studied. However, we do not observe nu 2(p(T))) scaled by the participant eccentricity to be independent of centrality. At higher PT, 2 1 <= PT <= 6 GeV/c, V2 scales with quark number for all hadrons studied. For the multistrange hadron Omega, which does not suffer appreciable hadronic interactions, the values of upsilon(2) are consistent with both m(T) - m scaling at low p(T) and number-of-quark scaling at intermediate p(T). As a function ofcollision centrality, an increase of p(T)-integrated upsilon(2) scaled by the participant eccentricity has been observed, indicating a stronger collective flow in more central Au+Au collisions.
