    In nonsmooth optimization,the study concerning the theory and application of second-order analysis of nonsmooth function has drawn much attention.Lemaréchal,Mifflin,Sagastizabal and Oustry(2000) introduced the UV-decomposition theory,which opens a way to define a suitable restricted second-order derivative of a convex function f at nondifferentiable point x.The basic idea is to decompose Rn into two orthogonal subspaces U and V depending on x,so that the first approximation of f in U is linear,and f's nonsmoothness near the point is concentrated essentially in V,and obtain second-order expansions.This paper mainly applies the UV-decomposition theory to a series of nonconvex function.Using the method of penalty function,the paper discusses the definition of the UV-decomposition of the penalty function,and the first-order and second-order expansions of the penalty function.

    Heat transfer in upward flows of supercritical water in circular tubes is numerically investigated by using the commerical CFD code FLLUENT.The numerical results were compared with the well-recognized experimental results of Yamagata.Five tubulence models were selected to carry out numerical simulations and the results of RNG k-ε model give a better prediction to the heat transfer than the other models.The comparison of results for different y+ showed that y+ which is no more than 1 would gives a better prediction to the heat transfer.The deviation of results for y+=0.1 is confined to 13%.The heat transfer performance for different heat flux was compared using RNG k-ε model with y+=0.1.The results showed that in the region with high specific thermal capacity and low heat flux the heat transfer would be enhanced.However,the impact of enhancement is weakened with the increase of the heat flux and the deterioration would occur at the critical heat flux.

    The vibro flagellin of Vibro alginolyticus and Vibro harveyi was pxtracted and then detected by high-speed centrifugal,cycles of differential centrifugation,vertical slab gel electrophoresis,western blotting and electronic microscopy identification.The result shows that the experiment has  already separated the purificated flagellin of Vibro harveyi and the original flagellin extracts of Vibro alginolyticus succesfully.The purification of Vibro harveyi has three clear protein lines by SDS-PAGE (relative molecular weight are 39.7,41.9and 42.7 KDa).Transmission electronic microscopy discovers that the protein assumes classical filamentous.This suggests that the flagellar filament of Vibro harveyi is made up of three subunit of flagellin whose molecular weight are 39.7,41.9 and 42.7 KDa respectively.The original flagellin extracts of Vibro alginolyticus have five to nine protein lines by SDS-PAGE,and the protein whose molecular weight are 36.8 KDa have remarkable immuno-genicity.

    Objective  To explore the effects of Astragaloside on cardiomyocyte apoptosis and the expression of telomerase in adriamycin (ADR)-induced cardiomyopathy in rats.Methods  Male SD rats weighing about 250 g were used to establish the model of Adriamycin-induced Cardiomyopathy，then randomized into groups:Astragaloside group，ADR group，control group and control+Astragaloside group.Apoptotic cardiomyocytes were detected using the terminal deoxynucleotidyl transferase mediated dUTP nick end labeling method (TUNEL).The expression of telomerase was determined by TRAP-PCR-ELISA method.Results  Compared with control group，ADR group had significantly higher index of apoptotic cardiomyocytes (P<0.05).The apoptotic index in Astragaloside group was less than that in ADR group (P<0.05)，however significantly higher than that in control group and control+Astragaloside group (P<0.05).The expression of telomerase in Astragaloside group was significantly higher than that in ADR group(P<0.05)，however significantly lower than that in control group and control+Astragaloside group (P<0.05).Conclusions  Myocardial apoptosis is an important mechanism of adriamycin-induced cardiomyopathy.Astragaloside therapy can inhibit cardiomyocyte apoptosis in adriamycin-induced cardiomyopathy，partly because it might increase expression of telomerase.
