摘要
给出原子结构拓扑指数（Ts）的定义．用它可表征各原子及其离子结构．结果表明，Ts与镧系元素的14种理化性质具有良好的相关性．由Ts建构的分子连接性指数（kmX），对无机物的，△fHm,U的预测结果优于文献方法．
Topological index (Ts) of atomic structure is defined as:T, not only presents solivlty for 1lo atoms and their ions but also has an excellent correlativity with 14physico-chemical properties (P) of lanthanide. The molecular connectivity index (7X) which is set up with T. predicts a,he and U of inorganic compounds, and the results are even more ideal than those of the literature method.
