| 1 | Large eddy simulation of flow in a street canyon with tree planting under various atmospheric instability conditions显示文摘In this work, a large eddy simulation (LES) model, which includes momentum and heat source (or sink) inside the tree planting layer, is proposed for the simulation of flow in a street canyon with tree planting. Vegetation canopy layer simulation shows that this model can be used to simulate the velocity distribution and temperature variation inside the canopy layer. Effects of atmospheric instability on flow and pollutant distribution in a street canyon with tree planting of an aspect ratio of 0.5 are studied. Results show that compared with the canyon with no tree planting (or the exposed street canyon), the canyon with tree planting shows a reduced wind circulation and pollutant exchange rate (PER) at the top layer of the street canyon, which induces the increase in the pollutant concentrations near road surface, leeward wall and windward wall. When street canyon atmosphere is under a strongly unstable condition, wind velocity decreases while pollutant concentration is increased in the areas near the street canyon top, road surface, leeward and windward walls, compared with the wind velocity in the street canyon with the neutral stratification. When street canyon atmosphere is under a weakly unstable condition, wind velocity weakens near the street canyon top and windward wall, but strengthens near the road surface and leeward wall, and pollutant concentration is decreased near the leeward and windward walls and is increased between the two rows of trees. When the street canyon atmosphere is under an unstable condition, PER is lower than that under the neutral stratification. | GU ZhaoLin1, ZHANG YunWei2 & LEI KangBin3 1 School of Human Settlements and Civil Engineering, Xi’an Jiaotong University, Xi’an 710049, China 1 School of Energy and Power Engineering, Xi’an Jiaotong University, Xi’an 710049, China 3 RIKEN Institute, Wako, Saitama, 351-0198, Japan | 2010 | Science China(Technological Sciences)2010，53，7： | 10 |
| 2 | Combustion synthesis, characterization and luminescence properties of barium aluminate phosphor显示文摘The blue-green emitting Eu2+ and Nd3+ doped polycrystalline barium aluminate(BaAl2O4:Eu2+,Nd3+) phosphor, was prepared by a solution-combustion method at 500 oC without a post-annealing process. The characteristic variation in the structural and luminescence properties of the as-prepared samples was evaluated with regards to a change in the Ba/Al molar ratio from 0.1:1 to 1.4:1. The morphologies and the phase structures of the products were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS), while the optical properties were investigated using ultra-violet(UV) and photoluminescence(PL) spectroscopy, respectively. The XRD and TEM results revealed that the average crystallite size of the BaAl2O4:Eu2+,Nd3+ phosphor was about 70 nm. The broad-band UV-excited luminescence of the phosphors was observed at λmax=500 nm due to transitions from the 4f65d1 to the 4f7 configuration of the Eu2+ ion. The PL results indicated that the main peaks in the emission and excitation spectrum of phosphor particles slightly shifted to the short wavelength due to the changes in the crystal field due to the structure changes caused by the variation in the quantity of the Ba ions in the host lattice. | A.H.

| 3 | A New Triterpenoid Saponin from the Seeds of Deccaria segetalis显示文摘A new triterpenoid saponin, named segetoside k, has been isolated from the seeds of Vaccaria segetalis. On the basis of chemical reaction and spectral analysis, the structure of segetoside K was established as:olean-12-ene-23a, 286-dioic acid 36, 16a-dihydroxy-28-O- [βD-glucopyranosyl-(1 →3)]-β-D-glucopyra-nosyl-(l →2)-β-D-glucopyranosyl-(l→6)-β-D- glucopyranoside(1). | Sheng Min SANG Min Liang ZOU Ai Na LAO Zhong Liang CHEN Jun UZAWA and Yasuo FUJIMOTO (Shanghai Institute of Materia Medica, Chinese Academy of Sciences, Shanghai 20003 1 The Institute of Physical and Chemical Research (RIKEN), Wako, Saitama 351-01, J | 2000 | Chinese Chemical Letters2000，11，1： | 2 |
