| 1 | Theoretical and numerical research of wire array Z-pinch and dynamic hohlraum at IAPCM显示文摘Dense Z-pinch plasmas are powerful and energy-efficient laboratory sources of X-rays,and show the possibility to drive inertial confinement fusion(ICF).Recent advances in wire-array Z-pinch and Z-pinch dynamic hohlraum(ZPDH)researches at the Institute of Applied Physics and Computational Mathematics are presented in this paper.Models are setup to study different physical processes.A full circuit model(FCM)was used to study the coupling between Z-pinch implosion and generator discharge.A mass injection model with azimuthal modulation was setup to simulate the wire-array plasma initiation,and the two-dimensional MHD code MARED was developed to investigate the Z-pinch implosion,MRT instability,stagnation and radiation.Implosions of nested and quasi-spherical wire arrays were also investigated theoretically and numerically.Key processes of ZPDH,such as the arrayefoam interaction,formation of the hohlraum radiation,as well as the following capsule ablation and implosion,were analyzed with different radiation magneto-hydrodynamics(RMHD)codes.An integrated 2D RMHD simulation of dynamic hohlraum driven capsule implosion provides us the physical insights of wire-array plasma acceleration,shock generation and propagation,hohlraum formation,radiation ablation,and fuel compression. | Ning Ding Yang Zhang Delong Xiao Jiming Wu Zihuan Dai Li Yin Zhiming Gao Shunkai Sun Chuang Xue Cheng Ning Xiaojian Shu Jianguo Wang | 2016 | Matter and Radiation at Extremes2016，1，3： | 7 |
| 2 | Pharmacokinetics of H002, a novel S1PR_1 modulator, and its metabolites in rat blood using liquid chromatography–tandem mass spectrometry显示文摘A rapid and sensitive liquid chromatography–tandem mass spectrometry(LC–MS/MS) method was developed and validated for the simultaneous determination of H002 and its phosphorylated metabolite, H002-P and hydroxylated metabolite H002-M, in rat blood. H001, an analogue of H002, was used as the internal standard.Blood samples were prepared by simple protein precipitation. The analytes and internal standard were separated on a Zorbax SB-C18 column with a gradient mobile phase consisting of methanol and water containing 0.1% formic acid at a flow rate of 0.2 mL /min with an operating temperature of 20 1C. The detection was performed on a triple quadrupole tandem mass spectrometer with positive electrospray ionization in multiple-reaction monitoring mode.Linear detection responses were obtained from 0.2–100 ng/mL for H002 and H002-M, while 0.5–100 ng/mL for H002-P. The intra- and inter-day precision(RSD%) was within 11.76%, with the accuracy(RE%) ranging from –9.84% to 9.12%. The analytes were shown to be stable during sample storage, preparation and analytic procedures.The method was applied to determine the pharmacokinetics of H002 in rats, and a preliminary study showed that the pharmacokinetics of H002 correlated with its biological effect on peripheral blood lymphocytes. | Jiaqi Mi Manman Zhao Shu Yang Shuang Yang Jing Jin Xiaojian Wang Qiong Xiao Jinping Hu Yan Li | 2016 | Acta Pharmaceutica Sinica B2016，6，6： | 5 |

| 7 | Research on the calibration method of precipitation micro- physical characteristics sensor显示文摘In order to diminish the effect of the ambient light and CCD pixel non-uniformity to the Precipitation Micro-physical Characteristics Sensor,a modified calibration scheme was designed and calibration experiments in sunny,cloudy,night,different location of sample space were carried out. Firstly,the characteristics of particle images which affected by ambient light and different location of sample space were analyzed. Secondly,the relevance betw een particle image features and parameters of image processing were discussed. Finally,the parameter setting scheme were determined,the radium of median filtering algorithm is 3 pixels,the defocusing radius of point spread function( PSF) is 7 pixels,the radium of erosion is 3 pixels,and the binary threshold is obtained from the Area-thresh relationship. The results show that the new scheme could deal with the image calibration well,the average errors of equivolumetric diameter was 0. 041 mm with standard deviation of 0. 115 mm,and the average errors of the axis ratio was 0. 011 with standard deviation of 0. 085. The new scheme works well in the field observation too,the observed axis ratio is consistent with the empirical relationship that proposed by Beard. The relative error of accumulation precipitation is-3. 06% after calibration,w hich is improved 1. 94% low er than the initial one without calibration. | SHU Xiaojian GAO Taichang LIU Xichuan HU Shuai | 2015 | Instrumentation2015，2，3： | 1 |
| 8 | The proposal and realization on more exact modeling of COIL performance显示文摘The chemical oxygen–iodine laser(COIL)is the shortest-wavelength high-power chemical laser that has been demonstrated.The characteristics,such as good atmospheric propagation,short wavelength and excellent transmission through optical fibers,make the COIL a good candidate for high-power laser application.To model the complete COIL lasing interaction,a three-dimensional formulation of the fluid dynamics,species continuity and radiation transport equations is necessary.The computational effort to calculate the flow field over the entire nozzle bank with a grid fine enough to resolve the injection holes is so large as to preclude doing the calculation.The approach to modeling chemical lasers then has been to reduce the complexity of the model to correspond to the available computational capability,adding details as computing power increased.The modeling of lasing in the COIL medium is proposed,which is coupling with the effects induced by transverse injection of secondary gases,non-equilibrium chemical reactions,nozzle tail flow and boundary layer.The coupled steady solutions of the fluid dynamics and optics in a COIL complex three-dimensional cavity flow field are obtained following the proposal.The modeling results show that these effects have some influence on the lasing properties.A feasible methodology and a theoretical tool are offered to predict the beam quality for large-scale COIL devices. | Shouxian Li Xiaojian Shu Yanyi Du Hua Su Yan Li Zhen Yu | 2013 | High Power Laser Science and Engineering2013，1，1： | 0 |
