摘要
文章构建了拓扑指数 m M,采用 m M的 0、1阶指数分别与 2 0种碱金属卤化物的核间距、16种碱金属卤化物的熔点、磁化率、键长和 5 1种离子水合热关联 ,拟合的回归方程相关系数 (相关指数 )分别为 0 .9965 ( 0 .9966)、0 .944 2、-0 .9873、-0 .995 5和 0 .993 9,基本上满足优级或良级标准 。
In this paper,the topological index ~mM of average energy of valence electron orbit is formed. By utilizing the zero and first order indexes, the nuclear distance of 20 kinds of alkali halide,the melting point,magnetic susceptibility,and bond length of 16 kinds of alkali halide, and the hydration heat of 51 kinds of ion, some regression equations are suggested. The relative coefficient (index) of the obtained equations is 0.996 5(0.996 6),0.944 2,-0.987 3,-0.995 5 and 0.993 9,respectively,which meets the good and excellent standards. Hence the calculation results are satisfying.
