This paper introduces the Hua construction and presents the holomorphic automorphism group of the Hua construction of the fourth *** the Bergman kernel function,under the condition of holomorphie automorphism and the standard complete or- thonormal system of the semi-Reinhardt domain,the infinite series form of the Bergman kernel function is *** applying the prop- erties of polynomial andΓfunctions,various identification relations of the aforementioned form are developed and the explicit formula of the Bergman kernel function for the Hua construction of the fourth type is obtained,which suggest that many of the previously-reported results are only the special cases of our findings.

The symmetry energy at the time of the production of intermediate mass fragments(IMFs) is studied using experimentally observed IMF multiplicities combined with quantum statistical model calculations(QSM of Hahn and St cker).The ratios of difference in chemical potentials between neutrons and protons relative to the temperature,(μn-μp)/T,and the double ratio temperature,T,were extracted experimentally in the reactions of64,70Zn,64Ni+58,64Ni,112,124Sn,197Au,232Th at 40A *** extracted(μn-μp)/TTscales linearly with δNN,where δNN is the asymmetry parameter,(N-Z)/A,of the emitting source and(μn-μp)/T=(11.1 1.4)δNN0.21 was *** experimentally extracted(μn-μp)/T and the double ratio temperatures are compared with those from the QSM *** temperatures-,T,and densities,ρ,extracted from the(μn-μp)/T values agreed with those from the double ratio thermometer which used the yield ratios of d,t,h and α *** the two analyses of the differential chemical potential analysis and the initial temperature analysis end up almost identical relation between T and ρ.T=5.25±0.75 MeV is evaluated from the(μn-μp)/Tanalysis,but no density determination was *** the extracted T value,the symmetry energy coefficient Esym =14.6±3.5 MeV is determined for the emitting source of T=5.25±0.75 MeV.

Fractures have an extraordinarily negative impact on individuals'quality of life and functional *** or disability of fracture is a major health issue with important clinical,social,and economic implications.1 Mesenchymal stem cells(MSCs)play an indispensable role in the initiation of the fracture repair process including the formation of a callus which is replaced by new *** use of MSCs in the treatment of fractures is very attractive as they can reduce the time of healing and occurrence of nonunion.

In Eq. (1), A?? and Nln(N/A)+Zln(Z/A) originate from the increases of the entropy and the mixing entropy at the time of the fragment formation, respectively. n (p) is the neutron (proton) chemical potential. is the critical exponent. In this work, the value of =2.3 is adopted from the previous studies[1]. In general coefficients, av, as, asym, ac, ap and the chemical potentials are temperature and density dependent.

In 2014, the researchers of Nuclear Data Research Group at IMP have carried out their research work on nucleardata measurements, calculations and fundamental research in heavy ion reactions. Some important results havebeen *** experimental setup for ADS nuclear data measurement has been developed in PISA terminal of HIRLF-CSRat IMP. The first beam test experiments for the whole system of the experimental including detection system anddata acquisition system were done by using measurements of emission neutron, and charged particle identification,energy spectrum, yield and angular distribution for 400 MeV/u 16O bombardments on Pb andWtargets. At present,the experimental measurement of accelerator driven white neutron energy spectrum in the range of several MeVto hundreds of MeV was done for the first time in China. The experimental results show that the experimentalapparatus works well, and the experimental technique is reliable and correct[1].

Type I X-ray bursts are the most frequent thermonuclear explosions in nature,resulting from thermonuclear runaway on the surface of an accreting neutron star[1].The breakout reaction 14O(α,p)17F from the hot CNO cycle may have a prominent impact on the burst light curve and burst ashes[2].However,insufficient experimental information is available to calculate a reliable,precise rate for this reaction[3].We proposed to address the experimental investigation of the 14O(α,p)17F using Time Projection Chamber(TPC)[4].

The amidoximation process of commercial polyacrylonitrile fiber was studied. The results showed that it is possible to prepare a chelating fiber, which present high adsorption capability to Au^3+ and reasonable mechanical property,by the amidoximation of PAN fiber,with the increase of reaction time or agent concentration,the coversion of CN group in PAN increases rapidly at first and then increases *** the reaction temperature is higher than that at which the paracrystalline region in the fiber is destroyed, the conversion of CN group increases greatly,but the mechanical property of the fiber begins to be inferior.
