In this paper, various boundary value problems of hyperelastic shells are considered. It is assumed that the storede-nergy function W（x, F） of the material,of which the shell is made, satisfies polyconvex conditions proposed by Ball[2].Existence of minimum points of the total energy of the shell in suitably chosen function spaces, and in suitably chosen finite element spaces is proved. Convergence of the finite element solutions is proved under certain regular conditions on the minimum points and some additional assumptions on W（x, F）. A Gradient type computing scheme for solving the finite element solutions is given, and global convergent result is obtained.

This article examines the effect and affect of historical representations in wartime Chinese theater and cinema,as well as the interplay between the two media.With the burgeoning of late Ming stories on stage and on screen,the fall of the Ming became a“chosen trauma”that connects the nation's past with its historical present.However the traumatic fate of the nation was never the actual subject of representation,but served to enhance the affective power of tragic-heroic figures.Focusing on A Ying's Sorrow for the Fall of the Ming,one of the most popular wartime historical plays,the paper studies the narrative structure,performance style and adaptation strategy of the play to demonstrate how patriotic spirit was foregrounded as the key to national survival.It was through the audience's resonation with the characters'passionate speech on stage and on screen that individuals,emotional attachment to the nation was consolidated,both horizontally across space and vertically through history.

119 Karst Springs, all with electric conductivity of less than 500 um/cm, discharging two carbonatic aquifers in Zagrosides of Iran are chosen and studied. The results indicate that the lithology of each Unit is well reflected in the chemistry of springs and the overall mineralogical composition of the aquifer can successfully be reconstructed from the hydrochemistry of the springs using a mass balance approach. The comparison of the chemistry of springs reveals that the significant difference are due to the dolomitic nature of one of the studied aquifers.

L. A. Fialkow proved in 1977 that σe（A）∩σe（B）≠φ(（σe（·） denotes Wolf essential spectra of operators）if A is quasi-similar to B on the Hilbert space H, denoted by A～～B. He further proved in 1978 that σ?（A）∩σre（B）≠φ if A～～B. We denote the non-semi-Fredholm domains of operators C\ρS-F（·） by σe0（·）. We shall give our result Theorem 1 which is a generalization of L. A. Fialkow’s.

Photooxidation of Hypocrellin A in neutral organic solvents has been studied in detail in our laboratory. The photooxidation product was Hypocrellin A-peroxide which was obtained by the interaction of Hypocrellin A in excited state and oxygen in ground state. Recently it was found that both photooxidation product and mechanism of the reaction
