Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers. The coupling of hydraulic model with water quality model is built up. The combined model was applied to a large complicated river networks with numerical hydraulic structure which influenced by strong tide, storm and heave rain. Visualization of computational results is realized by means of MapInfo, which displays the computational results in fast, convenient and accurate way.

However, the synthesis of circular nanostructures remains challenging due in large part to the difficulty in preparing functionalized cyclic polymers.4 Furthermore, reliance on macrocyclization routes to cyclic polymers restricts attachment of large side chains or dendrons to postpolymerization, and an efficient route to cyclic hybrid architectures of high purity is yet to be realized.

然而，由于合成功能化环状聚合物的难度很大，使得环状纳米结构的合成具有挑战性。4 另外，依赖于大环环合路线的环状聚合物受限于无法在后聚合过程中增加大型侧链或枝状体，同时目前也缺乏一种有效地获得高纯度环状混合结构的方法。
