作者： LIU Shuang-yan wang Gang-qiang liang zhi-ying wang Qiu-an State Key Laboratory of Chemo/Biosensing and Chemometrics College of Chemistry and Chemical EngineeringHunan University Changsha 410082 P.R.China

Two natural dihydrobenzofuran neolignans licarin A（1） and dihydrocarinatin（2） were systhesized from isoeugenol with Ag20-catalyzed biomimetic oxidative coupling as the key step. Four novel dihydrobenzofuran triazolylglycoside（3--6） were achieved in good yields via Cu（I）-catalyzed azide-alkyne cycloadditions of licarin A terminal alkynes with different azide acetylated sugar and deacetylation with sodium methoxide in anhydrous methanol. The structures of all the compounds synthesized were determined by elemental analysis, MS, 1H NMR and ~3C NMR. And the inhibition activity of synthesized compounds on a-glucosidase was determined by in vitro experiments. The results show that triazolyglycosides 3, 4, 5 and 6 show moderate inhibitory activity on a-glucosidase.

GATE REGULATION SPEED AND TRANSITION PROCESS OF UNSTEADY FLOW IN CHANNEL

引用

Journal of Hydrodynamics 2008年第2期20卷 231-238页

作者： TAN Guang-ming DING zhi-liang wang Chang-de YAO Xiong State Key Laboratory of Water Resources and Hydropower Engineering Science Wuhan University Wuhan 430072 China

The operation methods of channel and the speed of gate regulation have great influence on the transformation of flow in water conveyance channels. Based on characteristics method, a 1-D unsteady flow numerical model for gate regulation was established in this study. The process of water flow was simulated under different boundary conditions. The influence of gate regulation speed and channel operation methods on flow transition process was analyzed. The numerical results show that under the same conditions, with increasing regulation speed of the gate, the change rates of discharge and water level increase, while the response time of channel becomes shorter, and ultimately the discharge and water level will transit to the same equilibrium states. Moreover, the flow is easier to reach stable state, if the water level in front of the sluice is kept constant, instead of,behind the sluice. This study will be important to the scheme design of automatic operation control in water conveyance channels.

Hydrothermal Treatment of Polyamide 6 with Presence of Lanthanum Chloride

引用

Chinese Journal of Polymer Science 2016年第4期34卷 399-406页

作者： zhi-liang wang Jia-li Xu Qian Yuan Mahmoud H.M.A.Shibraen Jian Xu 杨曙光 State Key Laboratory for Modification of Chemical Fibers and Polymer Materials College of Material Science and EngineeringDonghua UniversityShanghai 201620China Lab of Polymer Physics and Chemistry Institute of ChemistryChinese Academy of SciencesBeijing 100190China

Hydrothermal processing of polyamide 6 （PA6） with the presence of lanthanum chloride （LaC13） was studied in the temperature region from 160 to 250℃. PA6 will be dissolved in the superheated water when temperature is above 160℃. And as PA6 is dissolved, hydrolysis will happen, which makes PA6 chains degrade. By adding LaCl3 in the hydrothermal environment, the PA6 hydrolysis will intensify, especially when the hydrothermal temperature is higher than 200℃. When the hydrothermal system cools down, the hydrolyzed PA6 segments will crystallize from the solution or remain dissolved in the solution depending on molecular weight. In addition, the hydrolyzed compound of LaCl3 would affect the crystallization of PA6 segments with proper size, and yphase would be presented.

Epidemic Spread in Networks Induced by Deactivation Mechanism

引用

Communications in Theoretical Physics 2008年第5期49卷 1357-1360页

作者： YU Xiao-Ling WU Xiao ZHANG Duan-Ming LI zhi-Hao liang Fang wang Xiao-Yu Department of Physics Huazhong University of Science and Technology Wuhan 430074 China

We have studied the topology and epidemic spreading behaviors on the networks in which deactivation mechanism and long-rang connection are coexisted. By means of numerical simulation, we find that the clustering coefficient C and the Pearson correlation coefficient r decrease with increasing long-range connection μ and the topological state of the network changes into that of BA model at the end （when μ = 1）. For the Susceptible-Infect-Susceptible model of epidemics, the epidemic threshold can reach maximum value at μ = 0.4 and presents two different variable states around μ= 0.4.

Dissolution, Hydrolysis and Crystallization Behavior of Polyamide 6 in Superheated Water

引用

Chinese Journal of Polymer Science 2015年第9期33卷 1334-1343页

作者： zhi-liang wang Jia-li Xu Lian-jia Wu Xin Chen 杨曙光 Hui-chao Liu Xian-ju Zhou State Key Laboratory for Modification of Chemical Fibers and Polymer Materials College of Material Science and Engineering Donghua University R & D Center Guangdong Xinhui Meida Nylon Co. LTD. Department of Mathematics and Physics Chongqing University of Posts and Telecommunications

The dissolution, crystallization and hydrolysis behaviors of polyamide 6 （PA 6） in superheated water （140℃ _〈 TH 〈 200 ℃） are investigated. The hydrothermal processing of PA 6 can be divided into four regions：（I） TH 〈 140 ℃, （II） 140 ℃ 〈 TH 〈 155 ℃, （III） 155 ℃ 〈 TH 〈 160℃ and （IV） TH 〉 160 ℃. Below 140 ℃, the hydrothermal processing does not have obvious impact on PA 6. Between 140 ℃ and 155 ℃, an annealing effect is observed that the hydrothermally treated resin shows increased melting temperature and lamellar thickness compared with the original PA 6. Between 155 ℃ and 160 ℃, the hydrothermal processing induces both annealing and surface swelling. Above 160 ℃, PA 6 dissolves fully in the superheated water. As PA 6 dissolves in the superheated water, hydrolysis takes place and becomes more prominent at higher temperatures and longer processing time. The hydrolysis induced molecular weight decrease fits an exponential decay.
