摘要
采用图论方法对取代冠醚的构造、构型以及手性构型和非手性构型进行计数。为了便于计数，取代冠醚的构型、手性构型和非手性构型的计数采用平面模型，并利用Ｐｏｌｙａ计数定理求出其计数母函数，最后使用计算机计算，结果列表给出。
In the paper the graph-theoretical method is used to enumerate the numbers of constitutions, configurations,chiral and achiral configurations of substituted crown ethers.For convenience'sake,a plane model is applied in the enumerating of the configurations and Polya theorem is used to find out all the counting generating functions.The numerical results are given by computer and tabulated.
