本文定义了键参数拓扑指数H_t~±。在一定条件下,H_t~±可转化为著名的Randic分子连通性指数的平方。并利用H_(11)相关了同构型杂原子分子的生成焓,晶格焓和反应截面等性质。
This paper defines the key parameter topology index H_t ~ ±. Under certain conditions, H_t ~ ± translates into the square of the famous Randic molecular connectivity index. The enthalpies of formation, lattice enthalpy and reaction cross section of H_ (11) related isomorphic heteroatom molecules are also used.
