Topological index ^mK of Orbital Average Energy and Its Application

In order to predict some physical-chemistry properties of alkaline halides, the topological index ^mK was proposed.The corresponding 0,1 index of ^mK was fitted in with the F center energy band,lattice energy,standard entropy and the internuclear distance bond length of alkaline halides.Some regression equations were also suggested,and their related coefficients(multiple correlation coefficient) difference is 0.990 3,0.998 6(0.998 8),(0.991 8) and 0.996 6(0.996 6),respectively.
