Topological index mW of valence electrons average energy level and its application

Enlightened by the topological index ()~mX of the Randic molecular connection the auther formed in this paper the topological index ()~mW of valence average energy level. Utilizing their zero and first order index and 16 kinds of alkali halides consisting of melting point,magnetic susceptibility , bond length ,and 20 kinds of alkali halides consisting of enthalpy of formation,ion hydrated energy; lattice energy,and 20 kinds of alklide-earth metal halides consisting of lattice energy ,and 19 kinds of metal oxides,metal sulfides,metal fluorides consisting of lattice energy, and 51 kinds of ion hydrated heat, and 80 kinds of ion standard heat of formation, the writer suggests some regression equations. Their related coefficient(index) different are 0.950 8, -0.989 3, -0.995 6, 0.986 0((0.986 4),) (0.981 7)(0.982 0), 0.996 5(0.996 9), 0.988 7(0.989 5), 0.994 9(0.995 4), 0.989 4and 0.981 0. meet the good and excellent standards. Hence the calculation gains better results.
