Kinetic Simulation of Gold Nanorod Growth in Solution Based on Optical Spectra

引用

Chinese Journal of Chemical Physics 2012年第2期25卷 135-141,I0003页

作者： Ying-ying wang Bo-xuan Li Silvije Vdovic Xue-fei wang An-dong Xia The State Key Laboratory of Molecular Reaction Dynamics Institute of ChemistryChinese Academy of SciencesBeijing 100190China

By monitoring the time evolution of the optical absorption spectrum corresponding to dy- namic information of aspect ratio （AR） and volume, we succeeded in following the growth kinetics of gold nanorods. The results indicate that the rods growth consists of two stages： seeds develop into rods with a fast AR increase and the rods grow big with constant AR. Here, a charge transfer model, involving positive charge transfer from Au（I） to seed and neu- tralization by electron from ascorbic acid, has been introduced to explain the autoeatalysis mechanism of rod growth. The good agreement between the numerical simulation based on this moldel and experimental results supports the proposed mechanism.

针对现有方法去模糊后图像缺乏足够清晰边缘的问题，提出了一种基于边缘引导与特征融合的分阶段图像去模糊方法，分两个阶段逐步去除模糊。首先，第一阶段应用含双交叉集成注意力模块(dual cross integrated attention module, DCIAM)的编解码网络学习不同尺度下图像的内容特征，初步去除模糊信息。然后，构建边缘分支网络(edge branch network, EBN)提取图像边缘特征。再次，设计了边缘引导去模糊模块(edge-guided deblurring module, EGDM)以耦合不同分辨率下图像的内容与边缘特征。最后，第二阶段通过级联的残差块和DCIAM进一步去除图像模糊，并通过引入自校准注意融合模块(self-calibrating attention fusion module, SCAFM)增强特征表达效果。实验结果表明：所提方法去模糊后图像的峰值信噪比和结构相似度均值分别达到32.78 dB和0.964,均优于其他对比方法。所提方法可以显著提高去模糊性能且去模糊后图像边缘结构更加完整。

Lattice configurations in spin-1 Bose–Einstein condensates with the SU(3) spin–orbit coupling

引用

Chinese Physics B 2020年第10期29卷 172-179页

作者： Ji-Guo wang Yue-Qing Li Yu-fei dong Department of Mathematics and Physics Shijiazhuang TieDao UniversityShijiazhuang 050043China Institute of Applied Physics Shijiazhuang TieDao UniversityShijiazhuang 050043China

We consider the SU(3) spin–orbit coupled spin-1 Bose–Einstein condensates in a two-dimensional harmonic trap. The competition between the SU(3) spin–orbit coupling and the spin-exchange interaction results in a rich variety of lattice configurations. The ground-state phase diagram spanned by the isotropic SU(3) spin–orbit coupling and the spin–spin interaction is presented. Five ground-state phases can be identified on the phase diagram, including the plane wave phase, the stripe phase, the kagome lattice phase, the stripe-honeycomb lattice phase, and the honeycomb hexagonal lattice phase. The system undergoes a sequence of phase transitions from the rectangular lattice phase to the honeycomb hexagonal lattice phase, and to the triangular lattice phase in spin-1 Bose–Einstein condensates with anisotrpic SU(3) spin–orbit coupling.

Processing and analysis of transient pressure measurements from permanent down-hole gauges

引用

Petroleum Science 2012年第3期9卷 330-335页

作者： wang fei School of Petrolcum Engineering China University of PetroleumBeijing 102249China

With permanent down-hole gauges （PDGs） widely installed in oilfields around the world in recent years, a continuous stream of transient pressure data in real time is now available, which motivates a new round of research interests in further developing pressure transient processing and analysis techniques. Transient pressure measurements from PDG are characterized by long term and high volume data. These data are recorded under unconstrained circumstances, so effects due to noise, rate fluctuation and interference from other wells cannot be avoided. These effects make the measured pressure trends decline or rise and then obscure or distort the actual flow behavior, which makes subsequent analysis difficult. In this paper, the problems encountered in analysis of PDG transient pressure are investigated. A newly developed workflow for processing and analyzing PDG transient pressure data is proposed. Numerical well testing synthetic studies are performed to demonstrate these procedures. The results prove that this new technique works well and the potential for practical application looks very promising.
