| 1 | Non-equilibrium between ions and electrons inside hot spots from National Ignition Facility experiments显示文摘The non-equilibrium between ions and electrons in the hot spot can relax the ignition conditions in inertial confinement fusion[Fan et al.,Phys.Plasmas 23,010703(2016)],and obvious ion-electron non-equilibrium could be observed by our simulations of high-foot implosions when the ion-electron relaxation is enlarged by a factor of 2.On the other hand,in many shots of high-foot implosions on the National Ignition Facility,the observed X-ray enhancement factors due to ablator mixing into the hot spot are less than unity assuming electrons and ions have the same temperature[Meezan et al.,Phys.Plasmas 22,062703(2015)],which is not self-consistent because it can lead to negative ablator mixing into the hot spot.Actually,this non-consistency implies ion-electron non-equilibrium within the hot spot.From our study,we can infer that ion-electron non-equilibrium exists in high-foot implosions and the ion temperature could be~9%larger than the equilibrium temperature in some NIF shots. | Zhengfeng Fan Yuanyuan Liu Bin Liu Chengxin Yu Ke Lan Jie Liu | 2017 | Matter and Radiation at Extremes2017，2，1： | 5 |
| 2 | Theoretical and simulation research of hydrodynamic instabilities in inertial-confinement fusion implosions显示文摘Inertial fusion energy(IFE)has been considered a promising,nearly inexhaustible source of sustainable carbon-free power for the world's energy future.It has long been recognized that the control of hydrodynamic instabilities is of critical importance for ignition and high-gain in the inertial-confinement fusion(ICF)hot-spot ignition scheme.In this mini-review,we summarize the progress of theoretical and simulation research of hydrodynamic instabilities in the ICF central hot-spot implosion in our group over the past decade.In order to obtain sufficient understanding of the growth of hydrodynamic instabilities in ICF,we first decompose the problem into different stages according to the implosion physics processes.The decomposed essential physics processes that are associated with ICF implosions,such as Rayleigh-Taylor instability(RTI),Richtmyer-Meshkov instability(RMI),Kelvin-Helmholtz instability(KHI),convergent geometry effects,as well as perturbation feed-through are reviewed.Analytical models in planar,cylindrical,and spherical geometries have been established to study different physical aspects,including density-gradient,interface-coupling,geometry,and convergent effects.The influence of ablation in the presence of preheating on the RTI has been extensively studied by numerical simulations.The KHI considering the ablation effect has been discussed in detail for the first time.A series of single-mode ablative RTI experiments has been performed on the Shenguang-Ⅱlaser facility.The theoretical and simulation research provides us the physical insights of linear and weakly nonlinear growths,and nonlinear evolutions of the hydrodynamic instabilities in ICF implosions,which has directly supported the research of ICF ignition target design.The ICF hot-spot ignition implosion design that uses several controlling features,based on our current understanding of hydrodynamic instabilities,to address shell implosion stability,has been briefly described,several of which are novel. | LiFeng Wang WenHua Ye XianTu He JunFeng Wu ZhengFeng Fan Chuang Xue HongYu Guo WenYong Miao YongTeng Yuan JiaQin Dong Guo Jia Jing Zhang YingJun Li Jie Liu Min Wang YongKun Ding WeiYan Zhang | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，5： | 4 |
| 3 | Structure modeling and spatial epitope analysis for HA protein of the novel H1N1 influenza virus显示文摘In recent months,a novel influenza virus H1N1 broke out around the world.With bioinformatics technology,the 3D structure of HA protein was obtained,and the epitope residues were predicted with the method developed in our group for this novel flu virus.58 amino acids were identified as potential epitope residues,the majority of which clustered at the surface of the globular head of HA protein.Although it is located at the similar position,the epitope of HA protein for the novel H1N1 flu virus has obvious differences in the electrostatic potential compared to that of HA proteins from previous flu viruses. | WU Di XU TianLei SUN Jing DAI JianXin DING GuoHui HE YunGang ZHOU ZhengFeng XIONG Hui DONG Hui JIN WeiRong BIAN Chao JIN Li WANG HongYan WANG XiaoNing YANG Zhong ZHONG Yang WANG Hao CHE XiaoYan HUANG Zhong LAN Ke SUN Bing WU Fan YUAN ZhenAn ZHANG Xi ZHOU XiaoNong ZHOU JiaHai MA ZhiYong TONG GuangZhi GUO YaJun ZHAO GuoPing LI YiXue CAO ZhiWei | 2009 | Chinese Science Bulletin2009，54，13： | 2 |
| 4 | Non-linear characteristics of Rayleigh-Taylor instable perturbations显示文摘直接数字的模拟方法被采用学习 Rayleigh 泰勒的非线性的特征在 200 μm 的脱离前面的不稳定的不安平面 CH 脱离目标。在模拟,古典电的热传导性被包括,并且 NND 差别计划被使用。从模拟获得的线性生长率同意 Takabe 公式。在脱离前面的密度不安的振幅分发为线性生长盒子被获得。Rayleigh 泰勒的非线性的特征不稳定的不安被分析,数字结果证明强迫的泛音的振幅分布与基本不安的很不同。泛音和他们的快生长的分布解释尖铁为什么发生在脱离前面的振幅的特征。数字结果也证明非线性的效果与两倍模式的阶段差别有关系起始的不安,和不同阶段差别导致改变的尖铁。 | Zhengfeng Fan Jisheng Luo | 2008 | Acta Mechanica Sinica2008，24，2： | 2 |

| 6 | Simplified methods to isolate,culture and purify olfactory ensheathing cells显示文摘Conventional methods for harvesting,culturing and purifying olfactory ensheathing cells are complicated,time-consuming,and poorly reproducible.Olfactory bulbs were detached from adult Sprague Dawley rats and olfactory ensheathing cells were isolated using shearing,dispersion processes.After the primary cultures reached confluence,the cells were purified using a three-step process.The olfactory ensheathing cells attached and grew rapidly.The purity of the olfactory ensheathing cells increased following the three purification steps,eventually exceeding 95%.These cells could be maintained for an extended period time in culture.This simple,inexpensive,reproducible method of harvesting,culturing and purifying olfactory ensheathing cells shortens the culture cycle and provides sufficient olfactory ensheathing cells of controllable purity. | Zhengfeng Lu Yixin Shen Peng Zhang Zhihai Fan Qirong Dong Min Wang | 2010 | Neural Regeneration Research2010，5，19： | 1 |
| 7 | An analysis of “eco-centric management” in China and methods to improve it显示文摘This essay focuses on the question “what does the evidence on environmental regulation and its implementation tell us about the extent of eco-centric management in China and how to improve it”. The first part will introduce eco- centrism, eco-centric management, and one major way to achieve eco-centric management in reality. Second, the environmental regulations of United Nation (UN) and China will be analyzed and compared to find out whether they are eco-centric. Moreover, the implementation of environmental regulation in China will be analyzed because regulation cannot exist without proper implementation. Three suggestions were given to improve eco-centric management in China: natural science research and public administration, environmental education, international cooperation. | Li Zhengfeng Zhang Fan | 2006 | Ecological Economy2006，2，2： | 0 |
