Study of Pre-equilibrium Fission Based on Diffusion Model

引用

Communications in Theoretical Physics 2006年第2期45卷 325-331页

作者： SUN xiao-jun ZHANG Jing-Shang College of Physics and Information Technology Guangxi Normal University Guilin 541004 China China Institute of Atomic Energy P.O. Box 275（41） Beijing 102413 China

In terms of numerical method of Smoluchowski equation the behavior of fission process in diffusion model has been described and analyzed, including the reliance upon time, as well as the deformation parameters at several nuclear temperatures in this paper. The fission rates and the residual probabilities inside the saddle point are calculated for fissile nucleus n＋^238U reaction and un-fissile nucleus p＋^208Pb reaction. The results indicate that there really exists a transient fission process, which means that the pre-equillbrium fission should be taken into account for the fissile nucleus at the high temperature. Oppositely, the pre-equilibrlum fission could be neglected for the un-fissile nucleus. In the certain case the overshooting phenomenon of the fission rates will occur, which is mainly determined by the diffusive current at the saddle point. The higher the temperature is, the more obvious the overshooting phenomenon is. However, the emissions of the light particles accompanying the diffusion process may weaken or vanish the overshooting phenomenon.

In pattern recognition,the task of image set classification has often been performed by representing data using symmetric positive definite(SPD)matrices,in conjunction with the metric of the resulting Riemannian *** this paper,we propose a new data representation framework for image sets which we call component symmetric positive definite representation(CSPD).Firstly,we obtain sub-image sets by dividing the images in the set into square blocks of the same size,and use a traditional SPD model to describe ***,we use the Riemannian kernel to determine similarities of corresponding subimage ***,the CSPD matrix appears in the form of the kernel matrix for all the sub-image sets;its i,j-th entry measures the similarity between the i-th and j-th sub-image *** Riemannian kernel is shown to satisfy Mercer’s theorem,so the CSPD matrix is symmetric and positive definite,and also lies on a Riemannian *** on three benchmark datasets shows that CSPD is both lower-dimensional and more discriminative data descriptor than standard SPD for the task of image set classification.

Measurement of the prompt neutron spectrum from thermalneutron-induced fission in U-235 using the recoil proton method

引用

Nuclear Science and Techniques 2019年第7期30卷 68-76页

作者： Tie He Pu Zheng jun xiao Key Laboratory of Radiation Physics and Technology Ministry of Education Institute of Nuclear Science and Technology Sichuan University Chengdu 610064 China Institute of Nuclear Physics and Chemistry China Academy of Engineering Physics Mianyang 621900 China

A measurement of the ^235U prompt fission neutron spectrum (PFNS) by the recoil proton method was performed at the Institute of Nuclear Physics and Chemistry, China. Details of the method, which include the calculation and validation of the response matrix, are presented. The PFNS for ^235U in the energy range 1–12 MeV, induced by thermal neutrons, was obtained. The measured spectrum in the low-energy region was in good agreement with previous work and the ENDF/B-VII library, except for minor differences. In the high-energy region, however, the relative height of the measured spectrum was greater, and an analysis of the experiment indicated uncertainties of 13% at 10 MeV and 24% at 12 MeV. Experimental results showed that the recoil proton method could be used to measure prompt fission neutron spectra. Some directions for future work are included.

作者： SHI xiao-jun ZHANG Shun-ming School of Economics and Management Beijing University of Aeronautics and Astronautics Beijing 100191 China China Financial Policy Research Center Renmin University of China Beijing 100872 China

This paper explores the existence of 3 equilibria for symmetric 2-individual 2-good CES/LES pure exchange economies. For certain parameterizations in the economies, we show analytically that there are no more than 3 equilibria. We generalize our analytical results of existence of 3 equilibria for a wide range of parameterizations. Then we provide examples of 3 equilibria and parameter zones of 3 equilibria for CES and CES/LES economies.

Expression and Purification of Recombinant MP-GFP Protein in Escherichia coli

引用

Agricultural Sciences in China 2011年第3期10卷 394-403页

作者： CHEN xiao-jun XU Han-hong Key Laboratory of Natural Pesticide and Chemical Biology Ministry of Education~South China Agricultural University Guangzhou510642 P.R.China School of Horticulture and Plant Protection Yangzhou University Yangzhou 225009 P..R. China

Guided pesticide is an unique compound resulted from the conjugation with carrier （amino acid, protein, sugars, etc） and the active pesticide ingredient. One of the attributes of the guided pesticide is its potential to accumulate at the site of the damaged points caused by pest or at the site of entry to the target pests, such as via inhalation, cuticular penetration, and oral digestion. Movement protein （MP） is a kind of protein coded by plant virus. A genetic fusion between green fluorescent protein （GFP） and movement protein resulted in the expression of a fluorescent fusion MP-GFP protein, which was fully biologically active in mediating the cell-to-cell spread of virus. In order to obtain a suitable carrier for a pesticide, fluorescent carrier MP-GFP was constructed. It was found that the recombinant MP-GFP protein was the inclusion body. The results indicated that optimized cultural condition for expression of recombinant MP-GFP protein was incubation at 37°C for 2 h and induction with 0.2 mmol L-1 IPTG （isopropyl-b-dthiogalactopyranoside） at 25°C for 4 h. MP-GFP protein was purified by using Ni-NTA resin. The expressed recombinant MP-GFP protein had both the fluorescence character of report GFP gene and moving character of movement protein. It could provide a guided carrier for studying the guided pesticide. It could also provide convenience for studying the delivery and distribution of the guided pesticide ingredients in the plant.
