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。

Many Landuse planning data information have the characteritic of complicated data structure, more kinds of storage formates and far-ranging distributing.
