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 girl looked longingly at the water jug, and as she was about to drink some, an old passerby suddenly entered begging for water. He was unfathomably thirsty, and could not walk anymore.

女孩用渴望的眼神望着水罐，接过来正想去喝时，突然从门外进来一过路的老人讨水喝，并且老人也是渴得厉害，都快走不动路了。

Under the unstaggered grids, the continuous equation is replaced with the elliptic different one of the pressure, which is derived by the finite-analytic method, and a modilfied new SIMPLER algorithm is proposed to be used as an equal-order pressure-velocity coupling scheme. A simple procedure is applied to determine the cell-face velocity independent of the under-relaxation factor used in solving the momentum equations.

The used behaviors /PATTERNING as a design strategy:By translating or imitating the accreting appearance of the nature,this project's main idea is to represent and struct a system of the biotope.On the first site, I use the strategy to observe the using behavior and walking routes in the environment,then the working system is bring naturally.The second site,I exploit all relations between water system and activities of daily livings to construct the scales of systemic types and new-used behaviors.It is an open system for a particular area.

惯性行为 PATTERNING as a design strategy：旨在藉由转译或模仿自然生成物的生成现象，再现且建构其在群构系统模式，在第一个基地所采取的策略是观察周边环境之使用行为及动线生成，衍生的系统顺应而生，第二个基地则是利用水系统与人们生活的各种关系，去建构系统的型态比例关系及新使用行为，是一种区域性的开放系统。

指出由于水垫塘中气泡被带入水体深处，使得水体存在溶解度梯度，溶解度沿着水深方向增加，深处水体能溶解更多的气体，在水流的紊动掺混下，高浓度的溶解气体被带入到较浅水深处，造成部分水体TDG过饱和。
