Considering the influence of fluid's viscosity and large amplitude sloshing, the 2-dimension coupling system composed of uncompressible viscous fluid and ideal elastic structure of rectangle aqueduct is studied by using ADINA to develop the models in this paper. Analyze the dynamic response of the rectangle aqueduct structure by large amplitude liquid sloshing. Under the horizontal harmonic excitations with different amplitudes, analyze the harmonic response of the rectangle aqueduct structure and fluid, include pressure on the tank wall ,free surface height and so on.

The β-CA of B.napus was located in chloroplast stroma and had the conservative motif Cys-X(subscript n-His-X2-Cys peculiar to β type carbonic anhydrases. In the secondary structure,α-helix, random coil,β-sheet, and β-turn were 39.88%, 39.27%, 16.31%, and 4.53%, respectively. The three-dimensional structure was constructed by homology modeling. The 3-D alignment of β-CA from B.napus and a monomer of β-CA octamer from pea showed that the 3-D structure of β-CA from B.napus could match well with the monomer. The alignment results Implied that β-CA from B.napus was a monomer of the β-CA octamer from B.napus.
