| 1 | A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding. | Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu | 2020 | Molecular Plant2020，13，9： | 14 |
| 2 | DMM:A dynamic memory mapping model for virtual machines显示文摘Memory virtualization is an important part in the design of virtual machine monitors(VMM).In this paper,we proposed dynamic memory mapping(DMM) model,a mechanism that allows the VMM to change the mapping between a virtual machine's physical memory and the underlying hardware resource while the virtual machine is running.By utilizing DMM,the VMM can implement many novel memory management policies,such as Demand Paging,Swapping,Ballooning,Memory Sharing and Copy-On-Write,while preserving compatibility with various architectures.The modular and hierarchical property of the DMM model efficiently incorporates the high-level policies and the low-level implementations,leading to a feature-adjustable VMM design.We presented the principle of the DMM model,and explained the procedures of various memory management policies under this model.Also,we implement the DMM model in KVM,an open source VMM.Our evaluation shows that the DMM model is efficient enough to provide the benefits of dynamic memory resource management with little performance impact. | CHEN HaoGang WANG XiaoLin WANG ZhenLin ZHANG BinBin LUO YingWei LI XiaoMing | 2010 | Science China(Information Sciences)2010，53，6： | 11 |
| 3 | A Novel Sensor Deployment Method Based on Image Processing and Wavelet Transform to Optimize the Surface Coverage in WSNs显示文摘A novel sensor deployment method utilize Discrete wavelet transform(DWT) is proposed, and the DWT is used to calculate the sub-band energy entropy to ascertain the coverage cavities in Wireless sensor networks(WSNs). We address the problem of deploying a limit number of sensors to optimize the coverage ratio in 3D surface, while it is a complex surface in space and sensors can be deployed only onto it. Another novel aspect of this paper is that the method followed utilizes an Artificial bee colony algorithm with dynamic search strategy(ABC-DSS), which mimics the behavior of bees, and the new modified ABC-DSS algorithm matches the sensor deployment problems on 3D surface well. The extensive simulations illustrate that comparing with the deployment method based on Particle swarm optimization(PSO) and ABC, the ABC-DSS which utilizes the wavelet sub-band energy entropy is functional and efficient on 3D surface deployment problems. | YANG Hang LI Xunbo WANG Zhenlin YU Wenjie HUANG Bo | 2016 | Chinese Journal of Electronics2016，25，3： | 9 |
| 4 | Brain-derived neurotrophic factor induces neuron-like cellular differentiation of mesenchymal stem cells derived from human umbilical cord blood cells in vitro显示文摘Human umbilical cord blood was collected from full-term deliveries scheduled for cesarean section.Mononuclear cells were isolated,amplified and induced as mesenchymal stem cells.Isolated mesenchymal stem cells tested positive for the marker CD29,CD44 and CD105 and negative for typical hematopoietic and endothelial markers.Following treatment with neural induction medium containing brain-derived neurotrophic factor for 7 days,the adherent cells exhibited neuron-like cellular morphology.Immunohistochemical staining and reverse transcription-PCR revealed that the induced mesenchymal stem cells expressed the markers for neuron-specific enolase and neurofilament.The results demonstrated that human umbilical cord blood-derived mesenchymal stem cells can differentiate into neuron-like cells induced by brain-derived neurotrophic factor in vitro. | Lei Chen Zhongguo Zhang Bing Chen Xiaozhi Liu Zhenlin Liu Hongliang Liu Gang Li Zhiguo Su Junfei Wang Guozhen Hui | 2011 | Neural Regeneration Research2011，6，13： | 8 |
| 5 | A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (http://gffzzc750bc0108fa4044s6xk6of655vwv6695.ffgz.tsg.suse.edu.cn/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants. | Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang | 2018 | Molecular Plant2018，11，11： | 7 |
| 6 | Ascorbic acid accelerates Wallerian degeneration after peripheral nerve injury显示文摘Wallerian degeneration occurs after peripheral nerve injury and provides a beneficial microenvironment for nerve regeneration.Our previous study demonstrated that ascorbic acid promotes peripheral nerve regeneration,possibly through promoting Schwann cell proliferation and phagocytosis and enhancing macrophage proliferation,migration,and phagocytosis.Because Schwann cells and macrophages are the main cells involved in Wallerian degeneration,we speculated that ascorbic acid may accelerate this degenerative process.To test this hypothesis,400 mg/kg ascorbic acid was administered intragastrically immediately after sciatic nerve transection,and 200 mg/kg ascorbic acid was then administered intragastrically every day.In addition,rat sciatic nerve explants were treated with 200μM ascorbic acid.Ascorbic acid significantly accelerated the degradation of myelin basic protein-positive myelin and neurofilament 200-positive axons in both the transected nerves and nerve explants.Furthermore,ascorbic acid inhibited myelin-associated glycoprotein expression,increased c-Jun expression in Schwann cells,and increased both the number of macrophages and the amount of myelin fragments in the macrophages.These findings suggest that ascorbic acid accelerates Wallerian degeneration by accelerating the degeneration of axons and myelin in the injured nerve,promoting the dedifferentiation of Schwann cells,and enhancing macrophage recruitment and phagocytosis.The study was approved by the Southern Medical University Animal Care and Use Committee(approval No.SMU-L2015081)on October 15,2015. | Lixia Li Yizhou Xu Xianghai Wang Jingmin Liu Xiaofang Hu Dandan Tan Zhenlin Li Jiasong Guo | 2021 | Neural Regeneration Research2021，16，6： | 6 |
| 7 | Autogenous inside-out versus standard vein and skeletal muscle-combined grafting for facial nerve repair显示文摘BACKGROUND:In the repair of nerve defects,collapse of the venous wall,as a result of vein grafting alone,could impede nerve regeneration.Therefore,vein lumens filled with muscle and nerve segments have been used to bridge nerve defects.OBJECTIVE:To compare the effects of autogenous,inside-out,vein-skeletal,muscle-combined grafting versus standard,vein-skeletal,muscle-combined grafting for the repair of facial nerve defects.DESIGN,TIME AND SETTING:A randomized,controlled,neuroanatomical,animal study was performed at the Animal Experimental Center and Laboratories of the Capital Medical University Xuanwu Hospital and the Peking Union Medical College Hospital from September 2007 to October 2008.MATERIALS:A total of 10 healthy,male,New Zealand rabbits,aged 6 months,were randomly assigned to inside-out,vein-skeletal,muscle-combined grafting and standard,vein-skeletal,muscle-combined grafting groups,with 5 rabbits in each group.METHODS:A 20-mm gap in the buccal branch of the right facial nerve was made in each animal,which was respectively repaired with inside-out,vein-skeletal,muscle-combined grafts or standard vein-skeletal muscle-combined grafts.MAIN OUTCOME MEASURES:At 6 months after implantation,evoked maximal compound muscle action potentials were recorded on bilateral facial nerves using electromyogram.Myelinated nerve fibers of the regenerating nerves were quantified using myelin sheath osmic acid staining.RESULTS:There was no significant difference between the groups in terms of ratios of bilateral amplitude and latency of compound muscle action potential(P>0.05).Moreover,morphology of regenerating nerves and quantity of myelinated nerve fibers were similar between the groups(P> 0.05).CONCLUTION:Compared with standard vein grafting,the inside-out vein grafting did not significantly improve nerve regeneration.Therefore,it is not necessary to utilize inside-out vein grafting for the repair of nerve defects,in particular with the combined use of autogenous vein and skeletal muscle grafts. | Yulu Li Zhiqiang Gao Zhenlin Wang Yonggang Liu Qiuhang Zhang | 2010 | Neural Regeneration Research2010，5，4： | 5 |
| 8 | Networking retinomorphic sensor with memristive crossbar for brain-inspired visual perception显示文摘Compared to human vision,conventional machine vision composed of an image sensor and processor suffers from high latency and large power consumption due to physically separated image sensing and processing.A neuromorphic vision system with brain-inspired visual perception provides a promising solution to the problem.Here we propose and demonstrate a prototype neuromorphic vision system by networking a retinomorphic sensor with a memristive crossbar.We fabricate the retinomorphic sensor by using WSe_(2)/h-BN/Al_(2)O_(3)van der Waals heterostructures with gate-tunable photoresponses,to closely mimic the human retinal capabilities in simultaneously sensing and processing images.We then network the sensor with a large-scale Pt/Ta/Hf O_(2)/Ta one-transistor-one-resistor(1 T1 R)memristive crossbar,which plays a similar role to the visual cortex in the human brain.The realized neuromorphic vision system allows for fast letter recognition and object tracking,indicating the capabilities of image sensing,processing and recognition in the full analog regime.Our work suggests that such a neuromorphic vision system may open up unprecedented opportunities in future visual perception applications. | Shuang Wang Chen-Yu Wang Pengfei Wang Cong Wang Zhu-An Li Chen Pan Yitong Dai Anyuan Gao Chuan Liu Jian Liu Huafeng Yang Xiaowei Liu Bin Cheng Kunji Chen Zhenlin Wang Kenji Watanabe Takashi Taniguchi Shi-Jun Liang Feng Miao | 2021 | National Science Review2021，8，2： | 5 |
| 9 | A Comparative Study on Hydrodynamic Performance of Double Deflector Rectangular Cambered Otter Board显示文摘In the present work,the hydrodynamic performance of the double deflector rectangular cambered otter board was studied using wind tunnel experiment,flume tank experiment and numerical simulation.Results showed that the otter board had a good hydrodynamic performance with the maximum lift-to-drag ratio(K_(MAX) = 3.70).The flow separation occurred when the angle of attack(AOA) was at 45?,which revealed that the double deflector structure of the otter board can delay the flow separation.Numerical simulation results showed a good agreement with experiment ones,and could predict the critical AOA,which showed that it can be used to study the hydrodynamic performance of the otter board with the advantage of flow visualization.However,the drag coefficient in flume tank was much higher than that in wind tunnel,which resulted in a lower lift-to-drag ratio.These may be due to different fluid media between flume tank and wind tunnel,which result in the big difference of the vortexes around the otter board.Given the otter boards are operated in water,it was suggested to apply both flume tank experiment and numerical simulation to study the hydrodynamic performance of otter board. | XU Qingchang FENG Chunlei HUANG Liuyi XU Jiqiang WANG Lei ZHANG Xun LIANG Zhenlin TANG Yanli ZHAO Fenfang WANG Xinxin | 2018 | Journal of Ocean University of China2018，17，5： | 5 |

| 11 | Exogenous abscisic acid coordinating leaf senescence and transport of assimilates into wheat grains under drought stress by regulating hormones homeostasis显示文摘Drought at the grain filling stage of wheat will cause premature leaf senescence, thus leading to considerable loss of wheat yield. Therefore, this paper aims to establish a cultivation technology for strong drought resistance, delayed senescence, and yield improvement based on the analysis of hormones homeostasis obtained by applying chemical control substances. Experiments were conducted with two genotypes of wheat. Four water irrigation treatments were applied to impose the water deficit, including well-watered control treatment(WW), mild water deficit(MiWD), moderate water deficit(MoWD), and severe water deficit(SWD). Exogenous abscisic acid(ABA) was sprayed on the plants at the anthesis stage of the wheat. As a result, exogenous ABA reduced initial senescence rate(r0), total duration of chlorophyll(Chltotal), rapid senescence phase(Chlloss), and the accumulated temperature at an inflection point(M) but improved the persistence phase(Chlper) of flag leaves under all of the four treatments. However, exogenous ABA produced inconsistent effects on photoassimilate relocation and grain weight under different treatments. It produced positive regulatory effects on grain weight under WW, MiWD, and MoWD treatments. On the one hand, spraying ABA during the persistence phase of flag leaves reduced the ratios of zeatin to gibberellin(Z/GA3), spermine to spermidine(Spm/Spd), and salicylic acid to ABA(SA/ABA),which prolonged active photosynthesis by stimulating high level of proline(Pro) and increased the activities of antioxidant enzymes, such as superoxide dismutase(SOD), peroxidase(POD), catalase(CAT), and ascorbate peroxidase(APX). Therefore, drought tolerance was enhanced, and more photosynthetic assimilates were accumulated. On the other hand, the rapid senescence phase and the transport rate of assimilates into grains were accelerated, resulting in higher grain weight, yield, and water use efficiency(WUE). However, under SWD treatment, exogenous ABA improved the ratio of SA/ABA, leading to low Pro content and low antioxidant enzyme activity of flag leaves in the rapid loss phase. Meanwhile,drought resistance declined and the transport duration of assimilates into grains was shortened, thus making photosynthetic assimilates redundant. Therefore, exogenous ABA can lead to the reduction in grain weight, yield, and WUE of wheat under SWD treatment. | Yongli Luo Wenqian Li Cui Huang Junhao Yang Min Jin Jin Chen Dangwei Pang Yonglan Chang Yong Li Zhenlin Wang | 2021 | The Crop Journal2021，9，4： | 4 |

| 13 | Dynamics Modeling and Robust Trajectory Tracking Control for a Class of Hybrid Humanoid Arm Based on Neural Network显示文摘In order to solve the problem of trajectory tracking for a class of novel serial-parallel hybrid humanoid arm(HHA), which has parameters uncertainty, frictions, disturbance, abrasion and pulse forces derived from motors, a multistep dynamics modeling strategy is proposed and a robust controller based on neural network(NN)-adaptive algorithm is designed. At the first step of dynamics modeling, the dynamics model of the reduced HHA is established by Lagrange method. At the second step of dynamics modeling, the parameter uncertain part resulting mainly from the idealization of the HHA is learned by adaptive algorithm. In the trajectory tracking controller, the radial basis function(RBF) NN, whose optimal weights are learned online by adaptive algorithm, is used to learn the upper limit function of the total uncertainties including frictions, disturbances, abrasion and pulse forces. To a great extent, the conservatism of this robust trajectory tracking controller is reduced, and by this controller the HHA can impersonate mostly human actions. The proof and simulation results testify the validity of the adaptive strategy for parameter learning and the neural network-adaptive strategy for the trajectory tracking control. | WANG Yueling JIN Zhenlin | 2009 | Chinese Journal of Mechanical Engineering2009，22，3： | 4 |
| 14 | Dynamic memory paravirtualization transparent to guest OS显示文摘This paper introduces dynamic paravirtualization, which imitates paravirtualization and aims at reducing VM exits of full virtualization with hardware support. In dynamic paravirtualization, VMM (virtual machine monitor) dynamically monitors and replaces the hot instructions, which cause most VM exits. It is transparent to the guest OS such that the legacy OSes can benefit from this optimization. Our study focuses on reducing the overhead of memory virtualization-dynamic memory paravirtualization (DMP). We implant a new memory management mechanism in VMM such that all user-mode page faults can be handled by the guest OS directly without VM exits. We implement a prototype of dynamic memory paravirtulization based on a version of KVM using Intel VT. Our experimental results show that our technique essentially eliminates the overhead of VM exits caused by page faults. Dynamic memory paravirtualization can achieve the effectiveness of paravirtualization without changing the source code of guest OS. | WANG XiaoLin SUN YiFeng LUO YingWei WANG ZhenLin LI Yu ZHANG BinBin CHEN HaoGang LI XiaoMing | 2010 | Science China(Information Sciences)2010，53，1： | 4 |
| 15 | Effects of exogenous ABA application on post-anthesis dry matter redistribution and grain starch accumulation of winter wheat with different staygreen characteristics显示文摘The objective of this study was to investigate whether and how exogenous abscisic acid(ABA)is involved in mediating starch accumulation in the grain and redistribution of carbohydrates during grain filling of two wheat cultivars with different staygreen characteristics.At blooming stage,plants of Wennong 6(a staygreen cultivar)and Jimai 20(control)were sprayed with10 mg L-1abscisic acid(ABA)for 3 days.The application of ABA significantly(P<0.05)increased grain filling rate,starch accumulation rate and content,remobilization of dry matters to kernels,and 1000-grain weight of the two cultivars.Exogenous ABA markedly(P<0.05)increased grain yield at maturity,and Wennong 6 and Jiami 20 showed 14.14%and 4.86%higher compared yield than the control.Dry matter accumulation after anthesis of Wennong 6 was also significantly(P<0.05)influenced by exogenous ABA,whereas that of Jimai 20 was unchanged.Application of ABA increased endogenous zeatin riboside(ZR)content 7 days after anthesis(DAA),and spraying ABA significantly increased endogenous indole-3-acetic acid(IAA)and ABA contents from 7 to 21 DAA and decreased gibberellin(GA3)content at 14 DAA,but increased GA3content from 21 to 35 DAA.The results suggested that increased yield of staygreen was due to greater starch assimilation owing to a higher filling rate and longer grain-filling duration. | Dongqing Yang Yongli Luo Yingli Ni Yanping Yin Weibing Yang Dianliang Peng Zhengyong Cui Zhenlin Wang | 2014 | The Crop Journal2014，2，Z1： | 3 |
| 16 | Review:Chromatic Dispersion Manipulation Based on Optical Metasurfaces显示文摘Metasurfaces are densely arrayed two⁃dimensional(2D)artificial planar metamaterials,which can manipulate the polarization,distribution,and amplitude of light by accurately controlling the phase of the scattering light.The flat metasurface has the potential to substantially reduce the thickness and complexity of the structures and allows ease of fabrication and integration into devices.However,the inherent chromatic aberration of the metasurface originating from the resonant dispersion of the antennas and the intrinsic chromatic dispersion limit their quality.How to effectively suppress or manipulate the chromatic aberration of metalenses has attracted worldwide attention in the last few years,leading to a variety of excellent achievements.Furthermore,utilizing the chromatic dispersion of metasurface to realize special functionalities is also of significant importance.In this review,the most promising recent examples of chromatic dispersion manipulation based on optical metasurface materials are highlighted and put into perspective. | Boyan Fu Xiujuan Zou Tao Li Shuming Wang Zhenlin Wang Shining Zhu | 2020 | Journal of Harbin Institute of Technology(New Series)2020，27，3： | 2 |
| 17 | Interactions between cytokinin and nitrogen contribute to grain mass in wheat cultivars by regulating the flag leaf senescence process显示文摘Premature senescence after anthesis reduces crop yields.Delaying leaf senescence could maintain photosynthetic activity for a longer period and lead to a higher photosynthetic rate.Recent studies have provided some insights into the interaction between cytokinin and nitrogen(N)in the regulation of plant development.In the present study,foliar application of exogenous 6-benzylaminopurine(6-BA)and lovastatin,an inhibitor of cytokinin synthesis,was combined with three N rates[0 kg ha^(-1)(low nitrogen,LN),240 kg ha^(-1)(normal nitrogen,NN),and 360 kg ha^(-1)(high nitrogen,HN)]in two wheat cultivars,Wennong 6(with a staygreen phenotype)and Jimai 20(with a non-staygreen phenotype).Flag leaf senescence was assessed using a Gompertz growth curve.Grain mass,dry matter accumulation and distribution,total N of flag leaf,and concentrations of zeatin riboside(ZR)and abscisic acid(ABA)were also used to evaluate the functional characteristics of flag leaves.Grain mass was negatively correlated with initial senescence rate(r_0)and duration of rapid chlorophyll loss(Chl_(loss)),whereas it was positively correlated with maximum senescence rate(r_(max)),average senescence rate(r_(aver)),persistence phase(Chl_(per)),total duration of flag leaf(Chl_(total))and inflection point cumulative temperature(M).Compared to Jimai 20,Wennong 6 had larger r_(aver),Chl_(per),and Chl_(total).The concentration of ZR was highest under the 6-BA×NN treatment,followed by the 6-BA×HN and 6-BA×LN treatments.However,the concentration of ABA showed the opposite trend.It was concluded that the staygreen phenotype Wennong 6 was associated with greater grain mass and altered cytokinin metabolism and could be classified as a functional staygreen type.Foliar application of 6-BA interacting with N at the NN level(240 kg ha^(-1))may be a beneficial strategy for improving grain yield of wheat by regulating endogenous hormones and the flag leaf senescence process.Increasing endogenous cytokinin promoted the transport of dry matter to grain. | Yongli Luo Yuhai Tang Xin Zhang Wenqian Li Yonglan Chang Dangwei Pang Xu Xu Yong Li Zhenlin Wang | 2018 | The Crop Journal2018，6，5： | 2 |
| 18 | Comparative study on the weight loss and lipid metabolism by tea polyphenols in diet induced obese C57BL/6J pseudo germ free and conventionalized mice显示文摘The role of gut microbiota in terms of host health is becoming increasingly important.In this study,the comparative effects of tea polyphenols(TPs)on weight loss and lipid metabolism on conventionalized mice(CVZ)and pseudo germ-free(PGF)mice(treated with antibiotics)were investigated.Our findings revealed that high fat(HF)diet considerably increased the body weight,total fat and upsurge lipid indices in CVZ mice but PGF mice were not sensitive to the effect of HF diet as CVZ mice.After the dietary administration of TP,body weight,perirenal fat and epididymal fat,liver weight,glucose(GLU)level,total chloestrol(TC level),high density lipoprotein-cholesterol(HDL-C)level significantly lowered in PGF mice as compared to CVZ mice group.However,the area of fat cells and triglyceride(TG)level were significantly increased in PGF mice.In CVZ mice,TP intervention resulted in a considerable drop in the Firmicutes/Bacteroides ratio as compared to PGF mice.The intestinal flora of PGF mice was severely reduced after antibiotic treatment,while TP administration restored intestinal diversity;the abundance of Akkermansia and Lactobacillus increased,whereas the abundance of Enterobacteriaceae and Prevotella reduced.Overall,we can assume that PGF obese mice administered with TP have less anti-obesity effects compared to obese CVZ mice. | Kashif Hussain Yingying Yang Jie Wang Hengjuan Bian Xi Lei Junjie Chen Qianying Li Li Wang Qingping Zhong Xiang Fang Yutao Wang Hong Wei Yigang Tong Zhenlin Liao | 2022 | Food Science and Human Wellness2022，11，3： | 2 |
| 19 | Large-area surface-enhanced Raman scattering-active substrates fabricated by femtosecond laser ablation显示文摘A rapid and simple approach to fabricate large-area surface-enhanced Raman scattering-active(SERS-active) substrates is reported.The substrates are fabricated by using femtosecond laser(fs-laser) direct writing on Silicon wafers,followed by thin-film coating of metal such as gold.The substrates are demonstrated to exhibit signal homogeneity and good enhancement ability for SERS.The maximum enhancement factor(EF) up to 3×10 7 of such SERS substrates for rhodamine 6G(R6G) at 785 nm excitation wavelength was measured.This technique could demonstrate a functional microchip with SERS capability of signal homogeneity,high sensitivity and chemical stability. | ZHU ZhiQing YAN ZhenDong ZHAN Peng WANG ZhenLin | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，9： | 2 |
| 20 | Study on the downhole permanent low frequency pulsating water injection technique显示文摘Waterflood technique with pressure fluctuation, especially with low, ultra low frequency, changes the continuous water flow into the flow with pressure fluctuation, and can prevent contamination precipitation, formation plugging and Jamin effect. It also can prevent the plugging of water injection well, decrease the pressure of waterflood and increase the rate of water injection. On the basis of the existing eccentric injection mandrel, used the energy storage character of air energy accumulator and the pressure switch character of pressure control valve, fixed the plunger valve for pressure control on the position of blanking plug, then developed one new injection mandrel with low frequency character, which can inject water continuously with low, ultra low frequency. Water fluctuation produced during the water injection affect the formation directly and is useful to break down, prevent plugging and augment injection. | WANG Zhiming QI Zhenlin XUE Liang | 2009 | 石油钻采工艺2009，31，1： | 2 |
